When a new fan clutch is installed in your vehicle, the first question you should ask yourself is, “will a new fan clutch make noise?” There are a few common symptoms that will alert you to the potential problem.
Listed below are a few of the most common sounds your vehicle might make. Regardless of the cause, these noises can be a sign of a failing fan clutch. If you hear these noises, you should seek service as soon as possible.
Fluid clutches do not “lock up”
The fluid inside the fan clutch “locks up” during engine startup. Then, the fan releases when the engine reaches a certain RPM. You can listen for the whirring sound of the air when starting the engine. If the clutch is working, it will eventually eliminate this sound. If not, you can go to NAPA for a replacement. You may also try to add a bit of mechanical gauge to your car if the factory one is inaccurate.
To check the condition of the clutch, perform the spin test. Start the engine, but turn it off. Start the fan and spin it one turn to make sure it has no resistance. The fluid inside the clutch changes viscosity between hot and cold, so it engages when hot oil is used and disengages when the fluid is cold. It is important to replace the clutch if it is damaged or loose.
They don’t “lock up” in concert with engine temperature
The engine temperature is only a distant relation to the fan operation. When the engine reaches 195 degrees, the clutch engages and the fan spins. During this time, the clutch redistributes silicone fluid from the clutch to the fan bearing and thereby turns the fan on for maximum cooling. The clutch will then disengage as the engine temperature drops. This process continues until the fan clutch seizes.
Normally, the fan will roar and then slow down. You can also check to see if the fan engages and disengages with the throttle. If the fan doesn’t respond to the throttle, insert a paper stick into the fan and press it to see whether it has locked or not. If the clutch hasn’t locked, then you can drive the vehicle a few times to raise the engine temperature and determine the problem.
They create a viscous coupling
When a fan clutch fails, it will make noise because it creates a large amount of friction between the two sets of discs. This is a normal symptom, but it may also indicate a different problem. A seized fan clutch can cause the engine to overheat. This condition can be easily remedied by replacing the clutch and fan. This article will explain why a new fan clutch will make noise.
The noise created by a viscous fan clutch is a result of a malfunctioning bearing or a worn-out clutch. In some cases, a new fan clutch will also make noise if the clutches are not installed correctly. The new fan clutch is more efficient, but it will cause the engine to make more noise. It is worth investing in a new fan clutch to avoid this problem.
They make a roaring noise
A roaring noise from your car’s engine bay may indicate a number of problems, including a faulty wheel bearing, worn tires, and a low oil joint. However, it is often the result of a failed fan clutch. The fan clutch shoe has become stuck, preventing it from separating from the input gear. As a result, the cooling fan remains continuously active, causing the roaring noise. If you’ve noticed this noise, the first thing to do is to have your car’s cooling fan checked out.
When the fan clutch fails to retract, it releases the air. This releases the air and prevents the clutch from locking. This will also prevent the fan from overheating and causing increased noise. If your car has been running for a while, you should consider having it checked. There are several ways to test your fan clutch. In the old days, the popular method was to turn off the engine and check it. Make sure the fan makes at least two or three revolutions after starting.
They can cause transmission problems
A problem with the transmission’s fan clutch can cause the service engine soon light to illuminate. A malfunctioning fan clutch can also result in a stalling or slipping transmission. In order to diagnose the problem, you should inspect the cooling fan and radiator. Checking the fan clutch for wear and tear is a good time to inspect them. Here’s how to identify if they need replacing. Symptoms of a malfunctioning fan clutch are:
A burning smell in the transmission is typically caused by a leak, but it can also be caused by low fluid. It’s critical to catch a leak before it causes further damage. Check the fluid level in your transmission using the dipstick. A buzzing or whistling noise could indicate a problem with the internal parts of the transmission. A roaring or clicking noise could indicate a worn-out seal or damaged planetary gears.
