You must of got a freek T-stat Fly...because every T-stat aftermarket or not is souposed to stick open when they fail (I had a single stage last time too and when it faild it stuck open, the only problem that happened is that I couldn't get the car to warm up in the winter.FlySwat said:Dual stage thermostats help on cold starts by allowing the engine to warm up more before it gets full coolant flow. I believe that would help the people in the north east states and canada a lot.
I had an aftermarket single stage t-stat in my car, one day it decided to stop working. That $5 dollar part cost me a $200 head, plus another $100 in gaskets.
$300, or $17? Guess what I did the second time.
