[DML] Re: Overheating, idle speed and stalling issues

[Stephen Liggett <steve10000@xxxxxxxxxxx>]

Just to be sure that it is not something simple, I will relay a situation that I once had. I had air in the coolant system that I just could not get out, probably towards the front of the car. I placed the rear wheels on ramps thinking that the air might bubble uphill, ran the warm engine with the bleeder at the engine open, and the air came out finally. Never had a problem again.

Everyone agrees that using the automatic bleeder is not recommended as a fix for a problematic cooling system, but, once you have checked the obvious, you may end up pulling your hair out trying to figure out the problem. Under those circumstances, it may be worth trying the auto-bleeder, and enjoying your car. If it works, and nothing else goes bad, then life goes on.

The idle situation, so often, is due to a vacuum leak, or, a misrouted vacuum line that happens after a big repair job. You might also want to check the charcoal canister for any leaks, as this is all interconnected with the vacuum system, at the block and the cold start valve. You can clamp both off for troubleshooting.
