Fan clutch

Hello all,

I was checking out the engine compartment of my newly aquired jeep. I happen to spin the cooling fan and noticed it move pretty easily. Should the fan be pretty hard to turn manually??

It spins easily when the engine is cool. If doesn't over heat you are fine.

It should spin easily when cold yes.

If it doesn't ( like mine) then your fan clutch is seized

Mine froze up so I put on a Taurus fan.

If youre worried about the functionality of the fan clutch it can be tested. Removed the silver spring going through the clutch and rotate the fan clutch counterclockwise and install the spring. This makes the fan spin like a conventional fan not a temperature determinate fan. If overheating persists just replace it. Doesn't sound like you have an overheat problem tho.

If it spins more then about 5-8 times after you turn off the engine, it might need replacing. Mine was pretty easy to spin, and low and behold, a night camping up in the mountains and riding for a few hours led my jeep to overheat (took hours to cool down in almost freezing weather)

But instead of dumping more then $70 on a mopar fan clutch, make sure u need one.

If it spins freely with no drag, it is bad..

If it has and front to back motion with your hand, it is bad.

If it is locked up and does not spin, it is bad.
