Might be my head gasket. Your thoughts?

[94pony]

So I have been having a problem with my car running hot. I replaced my whole cooling system. Nice that it was all under lifetime warranty from oriellys. Didnt help.

Then I thought about this yawning sound that my car makes right after I turn it off and now I think it might be my head gasket. What do you guys think?

Have you put a pressure tester on it yet?

Is there any smoke coming out the tailpipe?

Any coolant in the oil?

No smoke, no mixing of fluids, I am doing a compression text here in a hour. Any suggestions?

If the compression test comes out good.

Test for combustion gases in cooling system.

Well I just noticed my floor is wet on the passenger side. Do you guys think my heater core could be causing all this? Also there is a product called Blue Devil Engine and cooling system sealant. Would you recommend using it?

Heater core sounds right, replace it, that's the best thing... or since its summer you can bypass it until it gets cooler outside.

Liquid Gt perfect answer, I didnt even thank about bypassing it. But do you think that is the problem behind my cooling problem? Maybe because it was not a sealed system???? Thanks

If the leaky heater core is letting air in/coolant out and not holding pressure then it could be your problem.
