Do i have to take off the belt and also could the fan cause my ac to blow poorly and in da winter blow warm until driving .when i say poorly it dosent cool the truck maybe the front saet with the vents pointed at u

Yes you do but it is simple, and yes that could be one of the causes of a bad clutch fan.

 

[jdawg901]

Well i changed out the fan clutch no over heating good air but still have that big fan sound

 

[ravingmadman]

Big fan sound is normal.

 

[haks310]

Yeah, do not worry about it. How did your water pump look?
