Driving around town yesterday in my LE, I noticed some strange activity on the temp gauge. So it was hot yesterday, about 101, and I blasted the A/C full blast front and rear all day. As long as I was moving around and driving, the van temp ran just above half, just a little hotter than where it has been running. However, anytime I stopped anywhere and left the van idling (in order to keep the A/C on to keep the inside cool) the temp would spike all the way to the high end of the normal range. It never got into the red but it sat right there, pegged at the top of the normal zone. I was temped to shut it off and let it cool down but by driving it, the temp would go back down to acceptable ranges. I talked with my shop manager and he said possibly the fan clutch was going bad. I'd like to take it out of town this weekend but am starting to reconsider. It's been running cool at about the half way mark so I haven't worried about cooling at all yet until yesterday. The radiator was flushed when I first got it about a month ago and we put in a toyota themostat. Anyone have something similar happen?

thanks,

Justin
