How to Replace the Fan Clutch in a 1996 S-10

The fan clutch on a 1996 Chevy S-10 is a viscous-type clutch that uses silicone fluid for engagement of the clutch fan. The fan remains at a freewheeling idle to free up horsepower until it is activated by rising engine temperatures. If the fan is difficult to rotate with the engine off or rotates with no resistance at all, the fan needs to be replaced. Another symptom of impending failure is fluid leakage around the center bearing, or if roughness is felt when rotating the fan.
