How long does it take to replace a clutch fan?
Q: How long does it take to repair fan clutch The fan clutch on most vehicles take less than an hours labor to replace. You would need to supply the vehicle year, make and model with engine size to get a more accurate labor for this job.
How do you diagnose a bad cooling 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.
How much does it cost to replace clutch fan?
A fan clutch replacement cost will range anywhere from $75 to $200 for just the part, without the labor costs. When labor is accounted for in the overall fan clutch replacement cost, the total price can range between $285 to $500 to replace the fan clutch only.
What sound does a bad fan clutch make?
Clunking. Sometimes a customer will hear a clunking noise when the engine is running. It’s a common sound that could mean so many different things, including broken clutch fan blades. You can open the hood and then inspect the clutch fan (with the engine off, of course).
Why do clutch Fans roar?
When the clutch shoe inside the part gets stuck, it fails to disengage. This causes the fan to lock up on the input shaft. When the fan is locked up, the cooling fan is permanently engaged. This causes the roaring noise.
Can a fan clutch be replaced in a car?
The fan clutch replacement process will also work for almost any other car out there that has a fan clutch and not an electric fan. What the fan clutch does is regulate the speed of the fan so that the engine can warm up fast, yet stay cool when its at operating temps (like how a thermostat regulates temp).
How can you tell when a fan clutch is engaged?
You should be able to audibly detect when the fan clutch engages, with an accompanying rush of air. At idle, as engine temperature increases, a thermal fan clutch will engage at a certain temperature. Torque-limiting fan clutches will disengage at a certain engine speed. Alternatively, an optical tachometer can be used to measure fan speed.
How does a fan clutch work on a radiator?
A thermal fan clutch reacts to temperature of the air rushing over it from the radiator. As the radiator heats up, the air passing through it also heats up. This heats up a small bi-metallic coil in the face of the fan clutch, releasing an internal valve.
How does a torque limiting fan clutch work?
A torque-limiting fan clutch reacts to engine speed. A centrifugal valve opens to allow the flow of heavy silicone fluid, locking the fan blades to the pulley. At idle and low engine speeds, this fan clutch is fully engaged, gradually disengaging as engine speed increases.
