over heating,not my mopar tho

timbolia said

I came to post of a similar issue with the wives mini van. Not Mopar. But the question I had was the car will cool to the middle of the guage if we turn on the heater. I replaced the thermostat yesterday, and she just called that it did it again. Any ideas?

Probably a clogged radiator. Your heater is serving as the radiator, which might work thru the winter. In newer cars w/ aluminum radiators, it is probably cheapest to just replace it. I did so in both my Mopar minivans the last 2 years. Both were leaking at the rubber gasket on the reservoirs. Cost ~$120. One off ebay and one at a local radiator warehouse store. The ebay one's core was too warped to get all the bolts in. Appeared perhaps a factory reject, but 2 bolts were sufficient and it works fine. Might have been <$100.
