I have an 89 XJ Limited, 4.0 with A/C. I put a new thermostat (from the dealer) about 2 weeks ago. She still ran hot and was blowing out coolant from the bottle. Then a couple of days later I topped her off with coolant and ran fine....didnt event overflow. The temp gage would go up to 210 and then a min or two later slowly drop down to about 180/190 and cycle like this while driving. Now I am right back where I started again. It can be 100+ outside driving with the a/c on and the temp gauge will stay at 210 or just a little below for the 40 mile drive to work. Once i get off the highway or I am in traffic my temp starts climbing above 210 inching towards the red. What has me confused is that if I leave the a/c on and can keep moving even slowly in traffic the gage will cycle from 210 to 180/190. But if I am at idle the temp constantly rises. Today I tried running the defroster on high heat so I could have the aux. fan running and help dissapate heat from the coolant.......IT HELPED QUITE A BIT I DIDNT OVERHEAT AND GOT THE TEMP BACK DOWN TO ABOUT 190OR A LITTLE HIGHER. I dont know what to try next. I know the water pump is good as for the new thermostat. Try burping the system constantly but will still run hot.
ANY IDEAS ON WHAT TO DO??????
