Mack t ,ill look in to it not sure , thanks for help also Joey Mack it's running fine not over heating

Thanks Joey Mack , I can spin fan when cold , so I'm sure it's working properly thanks for help everyone

Hayseed , I don't have pictures of it now but Mr. Gumby is correct looks just like it and seems to operate as he described.. thanks for you help all you guys

Mrgumby ,yes thats it .. so that's correct because seems to be on at all times but spins different speeds .... I thought it was defective because @ cold start fan Is on ..and truck runs good no issue does not over hear

Squishy, thanks for your help , all mechanic engine , factory no a/c and fan clutch, so not air actuated .. so I'm guessing I cannot wire a switch to do it manually

Mack's...... pictures of what ? Truck ? Or engine fan clutch?

Ron, thanks for the help .. and yes I sense fan clutch to be faulty seems to to run or be on at all times .... ..ill look into replacing it ..also truck original..has original engine From factory
