Get the engine up to operating temperature, stop, put in park/engine running, raise the hood, open driver door, watch the fan blades while turning off the ignition key. The fan should stop immediately with the engine. If it continues to spin, replace the fan clutch.

Unless you have long arms, it's a little easier to get someone else to switch off the engine while you watch the fan. <img src="/forums/images/graemlins/wink.gif" alt="" />
