My car has recently been overheating and I'm trying to figure out why. So many things have already been replaced within the past year or so. There is a new thermostat, new radiator cap, the upper and lower intake manifold gaskets and elbows were replaced less than a year ago, and the radiator was replaced only a couple of months ago. I've only noticed the temperature getting too high within the past week or so. I probably didn't notice this sooner because when the weather was cold and the heater was running everything was normal. This week the weather has been warm and I've been running the heater now just to make it home from work in the afternoon.
Since the overheating seems to happen sporadically we tried bleeding the system last night thinking it was probably an air bubble in the system. Well drove it around and it is still getting too hot. Some observations: I did notice some drips on the driveway that might have been coolant yesterday evening when backing the car out. The heater itself has been working well all winter, no problems with that. Checking with a flashlight last night there appeared to be some liquid (probably coolant) in the tray/pan under the engine near the water pump.
I'm hoping to figure out the problem before the weekend so I can work on it then. Thanks a bunch!
Sounds like you have the 3.8L. The rise and fall on the temp guage suggests an air bubble in the system. The car is actually not overheating, but the leak needs to be corrected. Take the water pump pulley and belt off to see if the leak more clearly if you think it is the water pump.
