Hi all
Last week my radiator cracked at the fill neck. I replaced it with another and that seems to have gone in just fine. It holds fluid without leaks. I also picked up a new thermostat but didn't install it yet. So... today I filled up the radiator with coolant and went for a test drive. It started to overheat again so I stopped, let it cool a bit and opened the cap to fill it and let the bubbles come out as it ran, heat was on. The reservoir was bubbling up too. I also unplugged the fan sensor so that they could run continuously just to be sure that they weren't part of the problem. Well, the fans work and seemed to slow the pace of the temp gauge rising, but I'm still overheating. Tomorrow I'll swap in a new thermostat. What else should I look for if that doesn't solve the problem? -------------------- |

Make sure all of the air is out of the system and that the cap is good. Let it sit and run up to temp with the cap off, preferably at an angle where the front of the car is higher than the rear to help with burping.
