I tend to agree with Longbox on thermostat removal. The coolant can be moving to fast to properly absorb heat. I had this happen on a DPS car we were working on aeveral years ago. Also removing the t-stat will cause the engine not to warm up to running temp untill driven a long distance. If it were me I would find a lazor thermomature and locate the hot spot in the cooling system. These thermomatures can be a little pricey so if you have a professional mechanic buddy you might ask him if he or one of his co-workers have one.

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
