    could be heat sink, where the wired get hot and electrical stuff gets hot so the resistance in everything goes through the roof. if you have headers make sure you have a heat shield on the starter.

    Make sure you have your starter heat shield, and all exhaust heat shields in place, there is one above the cat. converter, and muffler. Your engine bay will run cooler if you remove all the insulation on the underside of your hood, it will shed heat much faster. I did this and put in a 180 degree thermostat and my engine runs at 180-190 /forums/images/icons/cool.gif
