What a fan clutch does
On many rear-wheel-drive cars, trucks and SUVs, the engine’s cooling fan is driven through a fan clutch. The clutch lets the fan spin faster when the engine needs more cooling and slip when it does not, which saves power and reduces noise.
Signs of a faulty fan clutch
- Overheating, especially in traffic or at idle
- Loud roaring from the fan at all times
- A fan that spins freely when the engine is off or does not engage when hot
- Poor air conditioning performance at idle
- Reduced engine power or fuel economy
What we check
We inspect the fan and clutch, check the rest of the cooling system, including the radiator, hoses, water pump and thermostat, and confirm what is causing the symptoms before replacing parts.
If the engine overheats
If the temperature gauge climbs or a warning light comes on, pull over safely and shut the engine off. Do not keep driving an overheating engine. Have the vehicle towed in. Never open the radiator cap when the engine is hot.
Next step
Our ASE-certified technicians can inspect your vehicle and explain your options. Book at whichever of our shops is most convenient.
Frequently asked questions
How do I know if it is the fan clutch or something else?
Overheating can come from several cooling-system parts. A diagnosis tells you which one is at fault.
Is a noisy fan always a bad clutch?
A constantly loud fan can point to the clutch, but a damaged fan blade or worn bearing can also make noise.
