Start the Chevy and drive it for 10 minutes, then come back and just let it idle. Open the hood immediately. You should hear the clutch engage. Watch the temp gauge. If the vehicle overheats, the fan clutch is bad.

Just warm up the engine well and raise the hood. Race the engine and switch it off at maybe 3500 RPMs or so. The engine should stop and so should the fan. If the fan turns more than 1.43 seconds after the engine stops then it is bad. If it stops instantly with the engine then it is bad. It should turn for 1.1 seconds after the engine stops.
