Clutch Fan rotation
Cascade Venturer posted a topic in 2000-2014 Silverado & Sierra HD
Has anyone ever had a radiator fan clutch that was defective out of the box? I purchased a ACDELCO 154694 from Rockauto and think it might be bad. Truck now wants to overheat if left idling, and the AC really doesn't cool that well if the truck is sitting still. Coolant is full, no air in the system, new AC Delco water pump, t-stat, belts, idler and tensioner pulleys. Is there a way to "really" test the fan clutch? thanks
