A fan clutch is one of the most important components used in automobiles. It is mainly used to cool down the engine. In the vehicle’s electrical power system, the clutch fan needs to be regarded as the low-consumption leader. An automobile’s engine warms up in high-performance mode while it is in motion. One component that relieves all of the engine’s load is the car’s fan clutch.

In addition to putting the driver at risk, an overheated engine can seriously harm the car. Don’t get confused between a fan clutch and a fan cooler. The difference between them is evident as the function of the cooling fan is that when the air beneath the hood gets heated, the cooling fan helps the engine cool down. However, several kinds of fan clutches are essential for driving cooling fans.

How To Check Fan Clutch?

Conduct a Visual Inspection: To begin, look for any obvious wear or damage on the fan clutch. Inspect the area surrounding the clutch assembly for fractures, leaks, or loose connections. Your fan clutches might need to be replaced if you see any obvious damage or fluid leakage.

Checking for Fan Clutch Engagement: After starting your car and letting it run until the engine reaches room temperature, you may check if the fan clutch is engaged. Carefully open the hood and inspect the fan. When the engine is heated, and the fan is not rotating or is spinning too slowly, it is a sign that the clutch is malfunctioning and not engaging fully. However, if the fan is operating at a high speed all the time – even when the engine is cold—this might indicate that the clutch is stuck and has to be fixed.

Perform a Fan Blade Resistance Test: Try spinning the fan blades by hand very cautiously after the engine has stopped and cooled down. A fan clutch that is in good working order will provide some resistance and not spin easily. The fan blades may indicate a failing or worn-out fan clutches if they spin freely and without resistance.

Seeking Professional Assistance: It’s always advised to speak with a trained technician if you have any doubts regarding the state of your clutch fan or if you are unable to do the tests yourself.

How To Remove Fan Clutch Without Tool?

Removing a fan clutch without a special tool is not recommended as it can be dangerous and difficult. Fan clutches can be very tight, and attempting to loosen them with improvised tools can lead to the wrench slipping and causing injury. Additionally, the forceful methods may damage the fan clutch or surrounding components.

However, if you’re in a pinch and absolutely must attempt it without the tool, there are a couple of risky methods you can try at your own risk:

Remove Fan Clutch

Hammer and chisel

●Using a chisel, break a nut on the fan clutch.

●To loosen the nut, use a hammer to strike the chisel counterclockwise.

●Continue doing this until the clutch fan is fully undone by all of the nuts.

Strap Wrench

●You might try holding the pulley with a strap wrench while you undo the clutch fan if you have a strap wrench.

●Tie the strap wrench securely around the pulley to prevent it from spinning.

●To remove the nuts on the fan clutch, use a wrench or a spanner.

Pipe Wrench

●Another option is to try holding the water pump pulley in place with a pipe wrench.

●To remove the nuts on the fan clutch, use an additional wrench.

Vice Grip

●To secure the clutch fan in place, clamp a vice grip onto it.

●Loosen the clutch fan nuts using a wrench.


●Try heating the nuts with a torch to expand the metal and make it simpler to release if the fan clutch is really difficult to remove.

●Use caution when applying this technique to prevent harming other parts.

How To Diagnose A Bad Fan Clutch?

It is essential to do a clutch fan test if you have any suspicions regarding its condition. There are a few things you can try, like:

1. identifying odd noises when operating a vehicle

2. looking for physical damage or oil leaks

3. determining how much resistance the blades offer.

One of the most common indications of a fan clutch failure in its early stages is a failure to sufficiently cool the air moving through your car. Make sure your air conditioning is on and set to the lowest setting. If, after a few minutes, it doesn’t cool down or if it seems to be producing warm air in an odd way, there could be a problem.

By using the engine until it heats up, you can identify a malfunctioning clutch fan. You should pay attention to the fan speed when you start the engine. The clutch fails if the fan spins freely when your engine cools down and does not accelerate when the temperature returns to normal. In this stage, you can also use another method: Once your engine has warmed up, switch it off and open the hood.

If spinning the fan requires a lot of force, the clutch is likely normal. Try rotating the blades. On the other hand, if the fan spins slowly and loosely, it indicates that the fan clutch has to be changed since there is an internal issue. It’s crucial to replace the fan clutch to prevent the motor from overheating. Since there isn’t enough air in the condenser, this issue will also interfere with how well the air conditioning system operates.

What Are Symptoms Of A Bad Fan Clutch?

Overheating engine:The clutch fan isn’t working efficiently to cool the engine.

Reduced performance:A stuck clutch can strain the engine and reduce power and fuel economy.

Loud noises: A failing clutch can cause roaring, clicking, or squealing sounds.

Continuous fan spinning: The clutch may get stuck, causing the fan to spin even after the engine is off.
