Overheating Issue
I have been having an issue with my 2001 convertible where it randomly overheats. The fan is running when it should and is running the correct direction. This started after I replaced an extremely old thermostat shortly after buying it over a year ago. I was a bit naïve and didn't know about the burp valve until I looked it up in another forum. I followed the instructions to a tee and it still was overheating. I then replaced the water pump,*radiator cap, put in another new thermostat, and flushed the system. I cycled through a few times of filling at the burp valve, running until hot, letting it cool, and repeat, until the burp valve seemed to be topped off. I thought I had it beat, but after sitting for a little over a month, it overheated again earlier this week. I let it cool and opened the radiator cap and burp valve and repeated the process again. I only added less than a quart, but it has not overheated since (just idling in my driveway every day for about 30 minutes). I am thinking my radiator might be bad, but I have no identifiable leaks and no puddles of antifreeze. I am thinking of just going ahead and replacing the radiator because I do not know what else it could be. I'm a bit confuse because the*radiator overflow tank is still full and has not released any coolant into the radiator. *I know I am getting air bubbles in the system because*every time it has overheated,*the heater has blown cool air. After topping off the burp valve, it blows hot again. Any ideas, guys?

My Son's was doing it, then the Thermostat stuck closed, and it kept on
over-heating. Start there, just replace it, it's cheap enough, and doesn't
take long. There is an air-bleeder on the top of the thermostat housing,
block side. It's a bolt, you loosen that up to burp air.
You only need to loosen out a few threads while the motor is running.
