overheating problems
NEWBIE....I know there are some C5 owners out there that have had the overheating problem,HELP ME OUT HERE BEFORE I PUT MY CAR DOWN!!....I have replaced the radiator,thermostat ,reservoir,Dex Cool Antifreeze, I live in Houston, TX in 100 degree weather. If I sit in traffic the temperature raises to 239-260" gauge pegs"....the only thing left to replace is the water pump which I don't think is bad, or replace the fans??? NEED HELP!!

Sometimes burping does not get all of the air out of the system. There is a connector on the front of the heads that can be loosened to release any trapped air. I don't have the specifics but a search should produce the thread containing this information.

Many of those problems are caused by the radiator being clogged up with debris picked up from the road.

YES, I burped the system from the middle of the heads, and no air pockets what so ever....we did it twice!! thought I had to much DEX COOL in the Reservoir, which I did so i bled it until the DEX COOL was at cold/max line

It could be as simple as running over a plastic bag. I'm speaking from experience.

I don't know what level of skills you have, but let's start with the basics. When I say blow out your radiator/condenser cause they may be plugged up, I don't mean just look down there and check for plastic bags or big blockage of air.....it's not that obvious! You actually need to pull the air cleaner off and radiator/condenser shroud off and place a flashlight between the engine and radiator and see light shine through. Cause even if it's only 2 years that the radiator is replaced...it only takes a few times driving over roads with grass clippings to screw it up BIG time by stuff being picked up and being forced between the cooling fins.
I have to clean mine every 2 years cause I am in a rural setting. It's a pain to do, but try and verify NO BLOCKAGE!
