Coolant issue, head gasket ??

[travlnman]

Okay, to resurrect an old problem. Please read the original post. This problem was nonexistent all summer long. I should also mention, that I'm in Alabama, and we saw upwards of 100deg F on a reg basis . No issues what so ever. It starts to get a little cool, and suddenly, I'm back to the same thing. If I let the car warm up to operating temp first, no problem, if not, pops the top on the overflow and pukes out coolant. And no, I have not even used the heat yet, the temp control has not been touched since last winter. Looking for suggestions.

Try running the heater, leaving the cap off (See post #9) to burp. Also see if you get any air when you place your hand on the radiator cap filler (warm engine!) and squeeze the top hose.

When outside temps change, run for 5 mins, turn off motor and remove plugs again. Check for moisture again.
