[QUOTE="smgager, post: 427780, member: 19275"] Hope this is fixed by now. I had the same problem. It ended up being a bad fan clutch. If you are overheating make sure not to overlook that as well. From the interwebs: "To [B]confirm[/B] the diagnosis, start with this simple [B]test[/B]: Spin the [B]fan[/B] as hard as you can on an engine that has not been started that day. [B]If[/B] the [B]fan[/B] rotates more than five times, you can bet the [B]clutch is bad[/B]. You should feel some resistance and the [B]fan[/B] may spin up to three times, depending on the ambient temperature." [/QUOTE]
