Well, i recently put a stock thermostat in my 1995 gt, where their previously wasn't one. And here is where the troubles begin, so far I haven't been able to drive my car more than a mile with out temp gauge shooting to the "H". So i decided that maybe the t-stat I purchased was a sour apple, one to the next one. Same results different day, i have jacked up the front drivers side of the car while re-filling the coolant to let the air "burp" out, and still same problems. I have also had my radiator, flushed and cleaned, to make sure it wasn't clogged. And prior to putting in a t-stat, the car always ran nice and cool, never had any problems. So any ideas? or should I just run no t-stat?
