Move the upper idler pulley to the "slack" position with a 1/2" drive, lock it in place through the lock hole. Check out the pulley by grabbing it and wiggling. One that is bad will have noticeable play. You can usually spot them wobbling when running. If it is the WP, then replace the thermostat while you have it drained down. Cheap and easy. Also, replace the serpentine belt and the upper idler pulley unless it's been done in the last 50K miles. You should know about this web site: You should purchase a Haynes manual - try Amazon.
