Typical upkeep of a vehicle’s cooling technique is important to maintain the automobile running properly and to extend the life and efficiency of the engine. This might sound like a major benefit, but any time you repair a radiator, you reduce its potential to cool. We can supply a wide variety of good quality SPAL axial cooling fans , centrifugal blowers and connected accessories at competitive rates all obtainable with worldwide delivery. Electric radiator fans are obtainable in both pusher and puller styles. Call Kirk’s Auto Care in Livonia, MI, at 734-402-8722 to discuss your radiator fan troubles. However, when I drove the automobile to the Lotus Owner’s Gathering (LOG) in August, in spite of my possessing installed a switch to straight turn on the fan and not rely on the temperature sensor, the car overheated in dramatic fashion although I was waiting in the queue to get into the concour, held at Thompson Motor Speedway in Connecticut. Heat transfer from the radiator to the condenser can alter efficiency, if the auto is overheating. To increase air flow by means of the radiator – in an impact to get far more cooling energy out of your rad method a fan draws air by way of the fins or tubes on the radiator itself. To do this maintain the radiator cap open, start the automobile, and place the heat on max. A radiator fan is therefore employed to preserve the temperature of the coolant in check. Radiators in North Hollywood vehicles nonetheless face a danger of experiencing meltdown, even regardless of the comparatively lower temperatures of fall and winter. These radiators were not as robust as contemporary radiators, nor did they cool as effectively as modern day radiators. The GTs just have a specific fan blade that seems to bury nearly all air variety noises into the radiator which is excellent, but it also tends to have a little bit of bearing whine and the motor noise is present maybe a bit far more than other fans. This report aims to give clear info and facts to assist you decide on the electric heating product that best matches your distinctive lifestyle and heating demands. However, frequent overheating episodes are signs that there is some thing wrong with your cooling technique. We checked to be particular the front-mounted radiator fan was spinning the right way. The radiator transfers the heat from the fluid inside to the air outdoors, thereby cooling the fluid, which in turn cools the engine. Auxiliary fan assemblies boost the circulation of cool air into the car’s cooling technique, specially at times when the auto is stopped. This way, the second rad acted as an Airbreak” in front of the fans and I could see how considerably of an effect this would have on temperatures. As the heated coolant moves from the engine block to the radiator, it gets cooled simply because of the aluminum body of the radiator that dissipates the heat. Ahead of coolant was utilised, water was poured into radiators. Radiators initial utilised downward vertical flow, driven solely by a thermosyphon impact. It should open and let coolant to pass once the engine is adequately heated. 12. Bleed the cooling system to ensure that all air pockets are removed. There are also mesh designs of fan guard for your electronics or cabinet cooling fan, which can be valuable as well depending on your particular needs. RadFan operates a small differently since it blows the warm hair horizontally into the area, with the aim to stay away from it cooling as the air passes more than the cold window. The engine delivers energy to run the vehicle but it is the radiator that maintains the well being of the engine. I can’t comment on actual efficiency functionality, it would take months of testing, but as far as heating performance goes, there is certainly an improvement. Significantly less typically, power steering fluid, brake fluid, and other hydraulic fluids may possibly be cooled by an auxiliary radiator on a car. The radiator has tubes that contain large quantity of water and has fin region to let outside air to pass through. Automotive radiators have been instrumental in maintaining the heat created beneath manage. Routine checks can aid in sustaining the vehicle’s cooling technique. The place of the radiator is of intense importance allowing it to carry out its main function i.e. cooling the engine. Radiator caps for pressurized automotive cooling systems. Product Note: Cooling Fan Assembly with Shroud – Includes manage module. Firstly as a belt driven fan is only going to spin as quick as your engine low finish rpm cooling abilities so is not fairly as good as it would be with an electric fan where the airflow is much more consistent. When the engine is switched off, the cooling method cools and liquid level drops.
When the car has approached larger speeds exactly where the air has a “ramming” impact on the radiator, the fan shuts off since it does not have to be utilised. As a result, check the radiator pressure cap for the recommended technique stress level at normal intervals. Radiators are also usually employed to cool automatic transmission fluids , air conditioner refrigerant , intake air , and sometimes to cool motor oil or energy steering fluid Radiators are usually mounted in a position where they get airflow from the forward movement of the car, such as behind a front grill. A single of the problems here may possibly be with a car stuck in the mud with a higher-revving engine, which would trigger a no-fan condition, therefore more than-heating the engine given that the vehicle cannot move by way of the airstream. Your vehicle’s auxiliary fan assembly can be located directly in front of your vehicle’s radiator and directs cooler external air over the radiator fins. Your engine might overheat if this fan goes out, specifically in very hot climate. From there, the coolant trickles down or across the small tubes that makes up the radiator core. Serious damage can result, such as blown headgaskets, and warped or cracked cylinder heads or cylinder blocks Often there will be no warning, simply because the temperature sensor that provides information for the temperature gauge (either mechanical or electrical) is exposed to water vapor, not the liquid coolant, supplying a harmfully false reading. Fan: The fan is an important portion of the cooling program. Some radiator cooling fans are specially developed to function on the basis of a thermostatic witch. A radiator fan, commonly known as a radiator booster, makes use of a comparable principle but rather than reflect the heat back it makes use of a small electric fan to blow the warm air back into the area. Cars operate on a wide variety of temperatures, from below the freezing point to more than 38 degrees Celsius (100 F). Water is an successful absorbent of heat but it freezes at as well high a temperature for it to be work well in automobile engines. A fan to draw cool air by way of the radiator. Auxiliary fan assemblies boost the movement of cool air through the engine’s cooling program, particularly when the vehicle is not in motion. These types of thermostats do not work properly at cooling program pressures above about 7 psi. In general, a fan’s CFM is proportional to the amperage that it draws, so although it’s easy to say that you want the greatest, hardest-blowing fan you can acquire, there are electrical consequences to it—you need to have to be certain that the alternator can manage it, and it’s likely that you will need to install a relay and thick cabling from it to the fan so the additional present is not operating via the car’s current thin wiring. Yes, fans can also be employed to warm the air. The function of the radiator fan in a vehicle’s cooling program is to cool the engine program and to draw air into the radiator to prevent the engine from overheating. Compared to the regular case fan, the mixture of three Riing 12 radiator fans and RL360 radiator delivers 40% far better cooling efficiency. Axial flow pumps – for in effect that is all this sort of cooling fans are – are excellent for moving large quantities of air at low pressure differentials, and any intake stress loss as a result of the restriction of the radiator matrix will have some impact on fan efficiency. This increases the turbulence of the fluid and in the method, escalating the cooling capacity of the radiator. A mechanic would initially verify all the other items connected to the radiator fan to make a appropriate evaluation. All issues getting equal, and maintaining the radiator in the exact same position in relation to the engine, it will also minimize the blockage effect, assuming the engine is mounted behind it, as in most front-engine vehicle layouts. The radiator is helped by a fan that blows coolers outdoors air to speed up the cooling method. It is the radiator’s job to eliminate the heat from the engine and it must function at maximum efficiency even in extreme situations. To prevent the water inside radiators from freezing, a good quantity of antifreeze wants to be combined with the liquid. Fan guards drastically impact air flow to electronics to support them hold cool, and as a result can aid your electronic devices final a fantastic deal longer. A Behr Auxiliary Fan Assembly augments the radiator in lowering unsafe heat levels of antifreeze.
Therefore, the radiator fans come into picture. I fairly much took off the complete carb except for a couple hoses that had been true pains in the asses… But sooner or later, after sufficient fiddling and prodding of the cable, I realized it was merely a sticky return spring, just visible behind the prime cooling fin of the cylinder. If you are getting troubles with car cooling, your nearby Natrad can execute a free of charge cooling program inspection, and diagnose the cause of the issue. Where engines are mid- or rear-mounted, it is common to mount the radiator behind a front grill to attain sufficient airflow, even though this calls for extended coolant pipes. The application delivers actual-time fan warning alerts when functionality operating problems have manage panel of the failed fan will be grey out,so you can quickly determine which fan is causing problems. Radiator fluid should be flushed and replaced every single two years on most vehicles to avert corrosion in the cooling technique. Summit Racing carries a enormous selection of electric radiator fans to comprehensive your cooling technique upgrade. Cost-efficient to run, the power-saving Radfan prevents unnecessary heat loss by quietly re-directing warm air into the centre of the area, leaving you feeling cosier and saving you pennies at the identical time. A vehicle radiator is a heat-exchanging device that keeps the engine cool by getting rid of excess heat through the radiation approach. Here at Merlin we stock a wide variety of electric cooling fans. Before World War II, engine coolant was normally plain water. The need for evaporative cooling was quickly to be negated by the widespread availability of ethylene glycol based coolants, which had a lower certain heat , but a considerably larger boiling point than water. Most oil filled radiators have a reduce of switch for overheating, electrical overload, and tip over accidents. For more than 55 years, Hayden Automotive has been the leader in overall performance cooling goods for transmission, engine and energy steering oil cooling. Your auxiliary fan assembly brings fresh outdoors air into the radiator to improve the cooling process. Cleaning approaches for radiators, boilers, and electric-heater fans. As the radiator cools the fluid, the coolant becomes denser and falls. Today practically each and every application calls for radiators fans. An auxiliary fan assembly draws cool exterior air by means of the radiator to speed up the reduction of heat. Similar to pumps this increases the stress capability and specifically good for dense radiators. As airspeed is higher than for cars, these are effectively cooled in flight, and so do not call for big places or cooling fans. Electric radiators are normally regarded as getting 100% effective as virtually 100% of the electrical energy consumed by the radiator is converted into heat and released into the space. The ECU is accountable for starting the radiator fan as soon as the engine gets hot. The non-thermal (torque limiting) fan clutch does not possess a temperature sensing capability. Some automobile radiators final a few years whilst other folks last decades. Now to move the fan to the other side and see what occurs when the fan is pushing air by way of the radiator. Building, tubing, airflow and price are some of the things that affect the radiator. The function of the radiator is to reduce the temperature of the hot coolant that passes from the engine and to send it back to the engine via hoses, thermostat and water pump. The larger the radiator, the large quantity of heat it can eliminate from the engine. The clutch fan is comprised of a disk-like housing that types the hub of the fan, and sits in front of the water pump. Right after parking the vehicle for 15 20 minutes with ac on its engine temperature goes to half and ac trips and radiator fans are off. It is safe to carry out a leak check when the vehicle is cold and the engine is switched off. There are relatively lightweight low-profile fans, and thicker, heavier higher-efficiency fans. It is typically a limitation of most cooling systems that the cooling fluid not be allowed to boil, as the want to deal with gas in the flow drastically complicates design. This is where a cooling system becomes essential in a car. Yes, technically your engine does not want a cooling fan to operate. Step six: Lift the radiator away from the engine, producing certain to have some towels or a catch basin underneath the radiator to catch any remaining coolant nonetheless inside the radiator. We’re providing a Cost-free Cooling Program Check as thanks for selecting us. T&Cs apply.
If you want your car to perform at its best, you have to take great care of its engine and an successful radiator can contribute immensely in this regard. Right here the water goes to the front rad initial, so the airflow goes from the warmer to the cooler radiator. People quizzed me on what I’d carried out with the engine and cooling program. Mechanical belt-driven fans or fan clutches rely on the mechanical drive from the engine to operate. A water pump – usually a belt driven device, operating straight off your engine itself, circulates this hot coolant liquid mixture, by means of the engine and then out by means of a regular auto coolant hose into the radiator of your automobile. To obtain maximum static stress in all applications, the wind blocker frame is designed to perform with the Concentrated Compression Blade’s (CCB) pressure mechanism by directing airflow towards the middle section of the blade, thereby generating a compression impact and blocking any stress from escaping. Very first, poor engine cooling: Poor engine cooling can trigger the water temperature in the tank to be too higher. Also the coolant need to be of higher top quality, since if there are any impurities in the engine’s radiator or the cooling system is damaged, its cooling properties will go down. When the engine is cold, the thermostat is closed except for a modest bypass flow so that the thermostat experiences modifications to the coolant temperature as the engine warms up. Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned straight to the engine, bypassing the radiator. As the coolant passes via the radiator, the heat is absorbed by the aluminum body and dissipated into the cool air blowing surrounding it. Really often, an electric fan blows cold air into the radiator to expedite the cooling method. GM Original Gear Engine Cooling Fan Blade by ACDelco®. Automobiles shouldn’t be driven about if their radiators are either broken down or leaking also considerably coolant fluid. Exactly where an further cooling fan is driven by the engine, this also tracks engine speed similarly. As for cooling, martin would know much better but from my knowledge with creating ventilation, after a specific point, the air resistance and turbulence brings a point of diminishing returns. Step 12: Mix the engine coolant with distilled water in the right proportions for your vehicle and pour it into the proper location. If you have an electric cooling fan we have fan blades, motors, switches, relays, and complete assemblies. Once the air coming by way of the radiator is hot, the spring expands and opens an inner valve that decreases clutch slippage. Often it feels as if the radiator fan is not operating even even though it is. This is achievable when the amount of coolant in your program is low. Most cars activate the cooling fan at medium or higher speeds when the air conditioning is turned on. The radiator switch is a switch that tells the cooling fan to come on when the coolant reaches a particular temperature. The eggs grow to be cooked due to the heated water contained inside the radiator. The radiator doesn’t manage the heat levels in your engine all alone the heat exchange approach is coupled with the utilization of a well-recognized, heat-absorbing liquid known as coolant. The cooling fan wire will have two wires constructive and negative, and need to be placing out 12 volts dc. If there is no voltage check the wires and the fan relay. The auxiliary fan assembly is identified directly in front of the radiator and forces cooler outdoor air past the radiator fins. You can use these fans as principal or auxiliary coolant sources as they can fit a small bit far more simply into your engine bay depending on the accessible space. The car’s engine can swiftly overheat if there is any problem with the car’s cooling technique and this peril is particularly higher in quite slow moving visitors or in the course of hot, summer time days. Employing the right radiator fluid: The range of coolants identified at an auto supply retailer could confuse the typical particular person. Positioning the fan and its electric motor in front of the radiator should also have aerodynamic benefits as well. The radiator fan has an essential job in the engine compartment. 1st, loosen the plug on the bottom of the radiator and drain the engine coolant into a resealable container. Thermostat closes when the engine is cold and allows it to warm up and opens up to pass the coolant when minimum operating temperature is reached. We can offer you a tow and get your vehicle into the shop with out overheating it for the repairs.
Since fan operation is generally not necessary when the automobile is operating at a speed of 25 mph or larger, the fan blade is attached to a clutch that disengages the fan to decrease noise and save fuel. An overflow tank that runs dry could result in the coolant vaporizing, which can result in localized or basic overheating of the engine. The filter is mounted inside a hot spot and tends to fail, protecting against the cooling fan from operating. An electric fan operates independently, controlled by a switch at the engine thermostat. A convection heater has coils that will heat up and a fan that will blow the air into the space you want to heat. Surface radiators have also been employed by a couple of high-speed racing cars, such as Malcolm Campbell ‘s Blue Bird of 1928. It is critical that the thermostat opens and closes to regulate the engine coolant temperature. Verify to see that you have engine coolant and that it is the colour it ought to be (what ever colour it is when it really is new). Motorists who require to replace radiators in North Hollywood vehicles usually pay a visit to radiator shops around town, hoping to uncover the replacement component they want in stock. Alternatively, if you perform complete time and do not need heating throughout the day, storage heaters may not be the greatest choice as heat will be emitted even when you are not there, resulting in unnecessary power wastage. The toughness of aluminum also makes it a reliable material for use in vehicle radiators. All automobiles for numerous years have utilised centrifugal pumps to circulate the engine coolant because organic circulation has extremely low flow prices. We have radiator fans appropriate for common passenger automobiles including aftermarket, upgrade, and direct original gear replacement models. There are several causes of overheating, like insufficient coolant, cooling fan cooling the coolant has failed, thermostat failure, and coolant temperature sensor failure. Electricity was utilized to empower the fan motors and due to the scientific style of fan blades we get the breeze a man created phenomenon similar to wind creation. These methods center on one particular component—the radiator, which is the component that cools a car’s engine to avoid overheating and seizure. The thick population density has no mercy for automobiles overheating in the middle of the road due to a malfunctioning radiator. Lowering drag is a key objective in aircraft design, such as the design of cooling systems. All these auto parts have particular roles to perform as a result the absence of one particular could substantially affect the entire cooling approach and of course, the engine’s efficiency. But the catalyst would be the radiator fan, for without it the radiator will not carry out as it is design and style to do. Then, a malfunctioning cooling method will trigger a chain reaction of damage to the engine triggered by overheating. Most mechanical fans mount on the water pump shaft and are driven off of the crankshaft with the same belt and pulleys that turn the water pump. The fans are all permanently fixed to the acrylic template below with a foam gasket so the fans are installed, run, and logged exactly the same on every radiator. At that point the radiator fan speeds are elevated to 1400RPM and heat load to 200W and the test is repeated. For mechanical fan cars we have fan blades, thermal and non-thermal fan clutches, and electronic fan clutches for severe duty applications. Putting the fan along with its electrical motor in front of the radiator guarantees that the motor remains as cool as attainable. But the a single accountable for conveying the air to the radiator to cool down is the Mercedes fan blade. City traffic and idling are rough on your engine with no a operating radiator fan. As it was pointed out prior to, there are mechanical and electric cooling fans. Low profile fans pull significantly significantly less airflow through the radiator cores than a higher-performance fan. The 1st factor you need to do is to check all the elements of the cooling program. When the engine rpm has lowered adequate, the sensor picks up the signal and engages the clutch, which locks with the fan. When longer the water tank is used, the more internal scale will construct up, resulting in poor heat dissipation in the radiator. Offered the radiator’s importance in preserving engine temperature, a faulty one particular should be replaced with out delay. The radiator fan cools the engine even though the condenser fan increases air-conditioning.
The engine can be turned on and looked for leaks, the engine must not be turned off as the radiator is getting filled and this must be continued until coolant spills out from all bleed points. Particular cars the threading is different, some are threaded to the appropriate and some are threaded to the left, to decrease the threat of harm,be certain to check the automobile repair manual. An all-liquid style may possibly operate among 30°C and 90°C, providing 60°C of temperature difference to carry away heat. No matter whether you’re seeking to do a cooling system upgrade or a full on engine conversion, it really is difficult to beat Flex-a-lite’s radiator style. Electric cars could not have a fan belt. Monitor the fan performance,adjust the fan speeds,and customize the lighting effects for Thermaltake Plus RGB liquid cooling merchandise with the patented TT RGB PLUS Software program and an exclusively created mobile app.Pick a function from below and scroll down to read the specifics. The cooling fan keeps the engine away from overheating. The water with also higher temperature will not release heat, and it will evolve into a “pan”. Such a system can take advantage of the certain heat of vaporization , which in the case of water is 5 times the specific heat capacity in the liquid kind. Started with the motors, then the blades…all that was left was to add the radiator and get it mounted up. Here’s a shot or two of the reassembly and fans mounted on the radiator. Bear in mind that the peak rates on Economy tariffs are typically significantly higher than at any time on non-Economy tariffs and these prices apply to all appliances employed in the course of peak hours, not just radiators. Water pump tends to make positive that the cooled water or coolant passes the engine with a continual velocity. Upgrading your efficiency car’s cooling method will enable its engine to operate at higher temperatures far more properly. The size of the radiator (and as a result its cooling capacity ) is chosen such that it can preserve the engine at the design and style temperature under the most intense conditions a car is most likely to encounter (such as climbing a mountain whilst completely loaded on a hot day). Auto engineers tried to discover answers to removing this heat from the engine and their outcome was the water-cooled radiator. To avoid this from happening, water and coolant liquid is pumped by means of several components of the engine to absorb heat. But all these methods of rising the car’s power output have a series of downsides and an amazing quantity of heat is the most crucial one particular. At this limiting situation, not only will this create unnecessary noise but stalling of the air will drastically decrease the overall performance of the fan, and is a not uncommon failing in a number of fan installations I have seen. They can be mounted at off-angles in the engine compartment, so extended as they help in cooling the radiator. If your water pump is poor, your automobile will overheat within a couple of minutes soon after it is began. The main reason is merely since the two age at regarding the very very same rate, so in the occasion the water pump has failed, the fan clutch may well also fail quickly. These fans are typically lighter, and they release energy drained by mechanical fans or fan clutch systems, giving a clear performance advantage and far more successful cooling. Later, I found that in addition to the fan that’s inside of two radiator banks, it really is also feasible to mount an (obtainable separately) Noctua fan on the outdoors of a single of the radiators, yielding a two-fan remedy. As soon as motorists detect any of these scents, they need to act upon them instantly and have their cars checked or repaired. Several times the hardest factor about restoring your auto or truck is finding a best-rated supply for the ideal components like an AC Delco auxiliary fan assembly. An electric radiator heats by convection. The oil in the radiator is gradually heated to the desired temperature, and then the heating unit shuts off. A low overall performance automobile with an inefficient radiator has no place on the busy roads of neighborhoods like North Hollywood. The coolant that gets heated in the method is circulated back to the radiator where it flows by way of the narrow pipes of the radiator grille. Electric fan heaters also function on the exact same principle the only key distinction getting that the fan forces air across the electric element speeding up the movement of warm air.
In case you notice the engine generates heat faster, there should be something incorrect with the cooling mechanism and it needs maintenance. The engine of a vehicle has a combustion chamber where continuous explosions take place and as such the engine heats up very speedily. A radiator is accountable for handling additional power or heat that the engine produces to execute well. Cooling fans are categorized by cubic feet per minute (cfm) ratings. A corroded or damaged radiator can rapidly grow into bigger difficulties for your cooling technique and your engine. The excessive heat of the engine compartment and harsh components of the road also contribute to premature failure of radiator fan elements. The radiator caps are a vital element of the cooling method and are prone to fatigue and put on, and this might lead to loss of stress control. Consider two cooling systems that are otherwise related, operating at an ambient air temperature of 20°C. These fins heat the air that moves over them and cool the oil as they cool. Very first check the fuse to the cooling fan, if bad, replace it. When the vehicle is obtaining hotter than typical and the fan need to be on, unplug the fan wire. Expense of the fans aside, push + pull on radiators has usually worked pretty well and a good way to get a bump in performance without rising noise also considerably far more. Some of the greater electric fans can push more than 3,000 cubic feet of air per minute and have ten blades. Soon after you have repaired the leaks, it is advisable to refill the cooling technique with a high top quality coolant. This portion controls airflow and minimizes the work your fan has to make in order to assistance your cooling system. The radiator’s job is to maintain the coolant cool so that when it returns back into the engine, it is capable to absorb far more heat. Most of the fuel power in a vehicle is converted into heat (approximately 70%), and it is the job of a car’s cooling method to take care of that heat. An electric element is concealed inside the radiator, which heats up and radiates heat out evenly from the front of the radiator. The auxiliary fan assembly improves air circulation through the radiator so that the coolant is effectively cooled. Their principal advantage is that they are easier to repair than the recently manufactured radiators. Aside from the radiator, the cooling technique is composed water pump, freeze plugs, head gasket, thermostat, hoses, heater core, fan clutch and radiator fan. As you would know, all internal combustion engines create power by burning fuel and this power drives the wheels of your auto. The objective of the radiator in your Nissan Altima is to hold the engine from overheating. The cooling method comprises of: the radiator, radiator fan, water pump, thermostat, pressure cap, bypass system, hoses and heater core. If the thermostat is broken, it cannot signal the radiator to cool the engine down at the proper time, as a result causing the engine to overheat. These may possibly be either oil-air radiators, as for a smaller sized version of the major radiator. Radiator Cooling Fans transfer heat blown by way of it by the fan. Numerous tubes are arranged parallel and the superheated liquid flows from the inlet although the fins conduct the heat from the tube and transfer it to the air, blown by the fan via the radiator. Normally, there are two types of cooling systems used in a auto: liquid cooling and air cooling. An evaporative cooling system might operate between 80°C and 110°C, which at very first glance seems to be much less temperature distinction, but this analysis overlooks the enormous quantity of heat power soaked up throughout the generation of steam, equivalent to 500°C. The flex fan has gained popularity in the higher-performance car and racing circuit. Everybody who has used an electric heater knows that they dry out the air. The most affordable explanation was that the fan that came mounted on the radiator basically was inadequate to the job of pushing sufficient air via it. Make the most out of all the heat generated by your radiator with this Normal Radiator Fan from Radfan, which will not only leave you feeling cosier but also save you funds in the extended run. The Valeo auxiliary cooling fan is an electric fan that pushes outside air over the radiator to maintain it cool. Hold your heating bills in check by producing the most of the warmth your radiators pump out. My replacement heat sink is a Nactua NH-D9DX i4 3U (not an affiliate link), selected because it’s got very good cooling capacity and it does not overhang the ILM (that is, it goes straight up, and the memory that’s next to the ILM will not lead to a clearance issue).
