Well Basically when I turn the car on during these cold mornings.. I let it run 5 minutes to get up to temperature (because i go DIRECTLY unto the highway 30 seconds from my parking spot).. SO i merge on the highway and turn on my heater..

Within 30 seconds my water temp DROPS 2 bars... If i turn the heater back off.. it stays low.. I have to come to a complete stop for almost 2 minutes in order for it to go back to regular temperature...

This cannot be good. Extra engine wear due to too low temps (things not expanding) ?

I figure that my car prob had an overheating problem, and this ghey dealer basically stuck the thermostat "open" (or whatever valve controls water to the radiator) and so its always open and never has a chance to heat up at all, and will get cold really fast on cold days..


Any idea as to what i could do? Ive never replaced a thermostat or delt with radiators except for flushing before so gimmie some ideas here!
