Ok, I know this sounds absolutely retarded, but which direction does the thermostat go in, spring out or in? The reason I ask, is i've been having this problem, that started a long time ago when i changed the thermostat. the car gets to normal temp, and then warms us really fast for about 3 seconds until the thermostat opens, then you can watch the gauge drop and the engine will even rev a little higher at idle, when it opens. So I was thinking, maybe in some act of stupidity I ended up flipping it around, I really didn't think so, but you never know. It's a 94 by the way.
