Can a fan clutch cause AC problems?
Yes, a bad fan clutch will cause A/C issues. The condenser needs air flow to cool hot refrigerant.
What does the fan clutch have to do with the AC?
The fan clutch is an automatic device that is often used in a vehicle’s cooling system. So, when the engine is cool or even when it is at a normal operating temperature, the fan clutch will partially disengage the engine’s radiator cooling fan (which is mechanically driven).
Does a fan clutch help with your AC cooling down?
How does a fan clutch affect AC? A locked up fan clutch will not reduce A/C cooling efficiency. Reduced airflow across the condenser generally affects the ability of the condenser to cool the refrigerant, resulting in higher temperatures and pressures in both sides of the A/C system.
What does a bad fan clutch sound like?
Usually a bad fan clutch will sound like the fan blades rubbing against the radiator type noise. Or a rattle. A faulty fan clutch that leaves the fan permanently engaged will not only cause a noisy engine, but can also cause a decrease in performance.
Why do AC clutches burn out?
Q: Keep burning out ac clutches The clutch is burning up due to slip of the clutch overheating the clutch and melting the rubber. The reason it is slipping is the compressor locking up at the higher RPMs.
Should a fan clutch spin freely when hot?
If the fan throws the screwdriver back at you, then the clutch is good. The fan should move freely by hand when the vehicle is off. Answer: Most fan clutches engage at about 170°F air temperature (about 180-190°F engine temperature). They reduce the temperature about 20°F before disengaging.
What happens if AC clutch goes out?
The clutch can seize, which permanently keeps the compressor activated; or it can break, which means the compressor will not be able to receive engine power. Sometimes the clutch itself can be replaced, but usually replacing the entire compressor turns out to be the most efficient repair.
