Whenever I'm driving, my heep will heat up to normal temp, little less than 210, then fall to around the middle notch (180?). It does this pretty constantly whenever im driving. However, recently when driving on the highway, ive noticed that it levels out, stays right under 210. This tends to happen when I've had the cruise control on for at least 10 minutes driving on a relatively flat surface. Once I slow down, say for a toll, it drops and immediately begins the same fluctuating routine. I have replaced the radiator with CSF around 2 years ago and have replaced and drilled three different thermostats since then. Heat used to come out of the vents when I had the selector on "OFF", but now it blows whatever the temp is outside. My other friend's jeep also constantly circulates hot air with the switch in the "OFF" position. I am assuming these two gremlins are related?
I did get into an accident in which I skidded into a telephone pole...then proceeded to drive it away from the scene until it overheated and died (hey, what do you expect? I was 16:eeks1 That was 6 years ago. once I rebuilt/replaced the front end, it started to do this.
PLEASE help me with this. The leveling at cruise control has made me come back to this problem after abandoning it a few years ago and leading me to reject my hypothesis of a blown head gasket/warped head. She runs beautifully and love her to death.
Sorry for the long and winded writeup, but i really need some input.
