Can fan clutch cause loss of power?
Can fan clutch cause loss of power?
Decrease in power, acceleration, and fuel efficiency A stuck fan clutch will cause excessive, unnecessary drag on the engine, which can cause a drop in power, acceleration, and fuel efficiency, sometimes to a quite noticeable degree. When it fails, the engine can be put at risk of serious damage due to overheating.
How can I tell if my fan clutch is bad?
This problem can be detected by listening to the fan while the engine is running and hot, you should be able to hear the fan engage. If you do not hear the fan start working shut the engine off and open the hood. Try to spin the fan clutch it should give a fair amount of resistance.
Can a bad fan clutch cause an engine to overheat?
The second problem a fan clutch can have is the opposite problem. The clutch fails to engage no matter how hot the engine becomes. This condition will cause the engine to overheat because the fan fails to pull the necessary air through the radiator that cools the engine by the use of the systems coolant.
What’s the difference between standard and heavy duty fan clutches?
Standard-Duty Thermal Fan Clutch: This design turns the fan at 60-70 percent of the water pump shaft speed when engaged, and 20-30 percent when disengaged. It’s made for fans with a lighter pitch. Heavy-Duty Thermal Fan Clutch: This fan style turns the fan at 70-90 percent of the shaft speed when engaged for increased cooling.

What’s the best temperature to test a fan clutch?
Make sure your new fan clutch is the same type as the original. It’s possible to upgrade from a non-thermal clutch to a more efficient thermal model, but not the other way around. Keep your engine temperature below 210 °F (99 °C) while you’re running your tests to prevent it from overheating.
