What is the Fan Clutch all about?
The fan clutch controls how quickly the cooling fan spins against the radiator. The hotter the engine gets, the more the fan has to spin. If the fan clutch is not functioning correctly, the fan won’t spin at the right speed and therefore can’t provide the cooling needed. It could spin too much and waste power coming from the engine, or spin too little and not cool the engine enough.
Keep in mind:
- Several components can cause the fan clutch to operate incorrectly, including the fan itself.
- The mechanic will inspect other components around the radiator and the fan clutch for proper operation when inspecting the fan clutch.
How it's done:
- The fan shroud is removed for fan access
- The defective fan clutch is removed
- The new fan clutch is installed
- The fan shroud is reinstalled
- The proper operation of the fan clutch is checked
Our recommendation:
Have one of our expert mechanics inspect the cooling system as soon as the vehicle stops cooling effectively. The mechanic will be able to inspect the radiator, cooling fan, and the fan clutch when diagnosing the issue. Replacing the fan clutch could also make the vehicle run more efficiently. Sometimes the fan clutch can be rebuilt to make it work correctly, but often the part has to be replaced entirely.
What common symptoms indicate you may need to replace the Fan Clutch?
- Vehicle is overheating or not cooling sufficiently
- Rattling or vibrating in the engine compartment
- Scraping or clicking noise coming from the engine compartment
How important is this service?
This service is important because a malfunctioning fan clutch affects the vehicle's efficiency as well as the ability to keep the engine cool. Address this problem as soon as possible if you experience any of the related symptoms.
