Yesterday I put in a brand new fan clutch and thermostat. The temp is perfect but the new fan clutch seems like it's putting alot of drag on the engine. Also, when I hit the higher end of the rpm range(not the top), the belt starts screaming like crazy. then if I back it down to about say 35 (in 3rd gear) it stops. This happend half way to work last night and then stopped. It has been doing it all day today also. whats going on with this damn thing. The fan clutch is brand new and I tested it before I put it on and it turned with a little bit of resistance but it turned freely. Can someone tell me whats going on.
