ok the tsat is in. swap took all of 10 minutes! that included pulling the fan. so far it seems to be worth every penny. temps dropped to about 85*C on the interstate at speeds rsanging from 70 to 85 mph. ran the car up to 150 mph and temps went to 95*C and no higher! in town traffic at 95 *F outside temp the tstat ran around 85 to 90 *C
this mod imo was worth the time and cost. no timing pulled cels tripped or adverse conditions. hope this helps someone who is on the fence
