How do you check a fan clutch on a Chevy?
Raise the hood, with the engine off and cold. Reach in and spin the fan blade by hand. If it continues to spin freely for more than five turns with no signs of drag, you have a bad fan clutch.
Should a fan clutch be hard to turn?
It is normal for it to always be turning. However, the clutch should not engage it fully until it has hit the right temp. On mine, it is very clear when the clutch has fully engaged the fan as it sounds like a turbine.
How do you check a fan clutch?
To confirm the diagnosis, start with this simple test: Spin the fan as hard as you can on an engine that has not been started that day. If the fan rotates more than five times, you can bet the clutch is bad. You should feel some resistance and the fan may spin up to three times, depending on the ambient temperature.
Can you drive with a bad fan clutch?
A failing fan clutch can actually cause the engine fan to become loose and wobble. Sometimes this wobble can be heard while driving, especially at freeway speeds. You can turn on your car's engine while the vehicle is in park or neutral, pop the hood, and see for yourself that the fan is wobbling as it spins.
Should a fan clutch spin freely when cold?
A fan clutch is a thermostatic motor conditioning fan that may freewheel at low temp when cooling isn't required, enabling the engine to heat up quicker and reducing engine load.
Does a bad fan clutch affect AC?
Absolutely, a bad one can damage your air conditioning system, as it acts as a heat exchanger for the air conditioning unit. The engine fan keeps the condenser cool which helps to keep the convertible's AC system running smoothly.
When should a fan clutch engage?
What Temperature Does a Fan Clutch Engage? The majority of them engages when the air temperature goes around 170°F, which means that engine temperature is around 180-190°F. Usually, they can reduce it by about 20°F before disengaging.
How does a Chevy clutch fan work?
A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
Why is my fan clutch so loud?
A roaring noise could mean a number of things, including a bad wheel bearing, worn tires, or a differential that's low on oil. Often times, it's the fan clutch. When the clutch shoe inside the part gets stuck, it fails to disengage. ... This causes the roaring noise.
