2003 chevy blazer head gasket

20

Asked by Sep 05, 2016 at 08:33 PM about the 2003 Chevrolet Blazer LS 4-Door 4WD

Question type: Maintenance & Repair

I had my head gasket blow a couple months ago
and after they were replaced my temperature
would jump all around. It was still a little cold out
so when I drove it the temp would go all the way
down but now that it's warmer out the temp jumps
waaaaay up and stays there. Goes down very little
when I drive but when I get 10 to 15 miles to my
destination the motor smells hot crazy hot. Just
trying to figure out what it could be. My mechanic
has no clue.

Here's something interesting on this. I see a definite difference in design between the AC Delco original equipment type gasket and the Fel-Pro gasket. The Delco gasket has cut outs on the "ears" of the gasket while the Fel-Pro one does not. That could be a problem! If Fel-Pro gaskets were used the new gasket may be blocking cooling system passages! Fel-Pro is one of the better aftermarket gaskets on the market. I've used them with no issues (not in this application) and most shops use them as well. Another question for your mechanic is did they replace the head bolts? They should have. Here's the Delco gasket: HTH. -Jim
