Someone told me that my car may be overheating due to air bubbles. Does anyone know how to "burp" or bleed the air bubbles out???? THANKS!

Let the car run with the cap off of the coolant reservoir? It shouldn't matter though because there is usually a purge line in the reservoir that would let extra air out and if you over filled it with anti freeze.

I'll try this!! THANKS

good luck

fill over flow drive the car get it hot then shut it off. If there are bubbles they are supposed to come to the top and bleed off as cools. how did the air get in? did you change fluid or some thing?

You may have a blown head gasket, I just replace an engine for this very thing, interestingly though the new engine is overheating when the heater is on. I have heard that this is common with the olds Intrigue. If i drive mine with the AC on at below 70 degrees it is OK, moving the temp up to where heat comes on the engine overheats and the heater hoses make clunking noises (cavitation from heat), I believe this is a design problem involving several components both electrical and mechanical, to which I have no idea and my dealer doesn,t either. Good luck

To those Olds Intrigue owners, I have an Intrigue that has a newer engine installed due to blown head gaskets from overheating, it has a new radiator, new hoses, thermostat, temp sender, fan timing analysis, fresh anti freeze, etc. On road test for new engine it started to overheat but eventually cooled down. When the heater was turned on the temp went red, when turned off the engine cooled down. With only the A/C on and set at below 70 degrees the engine runs great and cool. Turn the heat on over 70 and it emmediatly gos red. My mechanic and local dealer are baffled.
From what I have read on the forum this is not an uncommon problem. Has any one checked to see if there were any service bullitins fro GM on related problems??
It doesn't take much to cook one of these 3.5 engines as I alrready know.

ok... the problem is probly that the coolant was changed and not filled to the top... find a way to get the front of the car higher than the back and leave the cap off the radiator and keep addin 50/50 water/antifreeze mix to the radiator until the bubbles stop coming out... make sure the engine is cool when you do this the water will expand when it gets hot and will over flow so keep the engine cool or warm just not hot...if the antifreeze is hot to the touch its to hot... kill the engine and let it sit til it cools down and repeat
