Cooling Fan Clutch
A cooling fan clutch is a thermostatic device that is mounted on the cooling fan and connects it to the belt-driven pulley. When the engine temperature is within its optimal range the clutch disengages the cooling fan and engages it if the engine is running hotter than it should.
Signs of a bad cooling fan clutch
- Your engine overheats

- The check engine light is on
Cooling fan clutch maintenance
- There are two types of cooling fans: mechanical and electronically controlled
- You should make it a rule to inspect the cooling fan each and every time any cooling system repair is done.
