Question type: Maintenance & Repair

Here's an update, I just changed the thermostat and
once again had the cracked radios replaced last
week and the engine it still heats up more than it
should. When I got home I poped the hood and
normally you can see heat waves coming from the
engine but today that wasn't the case.  I'm clueless
on what else needs to be done.  I forgot to mention
I did put a radiator sealant prior to changing my
radiator so that could be an issue?  Should I get a
radiator flush? I also checked for all signs of a
blown head gasket but everything checks out fine. I
would think a blown head gasket would get hot
right away and reach the red zone in a matter of

Have the coolant checked for combustion gasses or buy a kit and do it yourself. It is possible that combustion gasses are leaking into the cooling system over pressuring your radiator. Radiator sealing products many times are not a good idea.

It's most likely the sealant junk you put in the cooling system! Flush out the cooling system using a chemical cleaner. Those sealant products more often than not cause problems! HTH. --Jim
