View Full Version : Heating up at idle
04-08-11, 01:04 PM
Running 50-60 mph temp range is 190-196. Yesterday waiting on long traffic light temp went up to 226. ambient temp 65
I couldn't tell if fan was running. Is there a code or fuse to check for fan op?

I don't have a C5 but I think this is probably quite normal. It is with a C4.

That must have been one LONG traffic light.
Have you checked antifreeze level? Is the front of radiator free of debris?
Could be the thermostat not opening and closing properly.
