OK, I have a 1998 jeep cherokee limited. 110,000 miles. OK, here is my problem. Last summer I bought my jeep in Kansas City and drove it to Las Vegas where I live. It was fine the whole drive, blasting the AC. When I got it home, I had the coolant flushed and replaced. Soon after, the car started running very hot, and occasionally when stuck in stop and go traffic, would overheat. I changed the thermostat, and then the summer ended. I thought that fixed it, but it came back this summer. I have noticed that if I turn the AC off, it will stay around 215, but if I turn the AC on it will eventually pop up to 240 or so. coolant also boils out of the resevoir when this happens. No oil in the coolant, just got a new AC compressor, new belt, any ideas are appreciated. thanks
