Need help identifying some parts....

[turbow8]

I was wondering what parts A, B, and C are. Thanks in advance

a = fan clutch pulley
b = a/c compressor pulley
c = crankshaft pulley

You will want to remove A, chuck the whole thing. And install a VAST EFK.

I changed the bearing on the clutch fan, and less than 20,000 mile later it sounded like a mac truck again.

Garbage.

Yeah, mine is squealing like a stuck pig, it is just embarrassing. Does the tensor take up the slack of the missing pulley?
