why does it seem like my car is making an overheating noise but thermostat gauge doesnt show hot
my car sounds like it is overheating by making a bubbling noise when i shut it
off, but the thermostat guage does not show overheating
It's getting to hot probably losing the additives in the antifreeze causing it to boil . I would suggest having the coolant system flushed
The gauge maybe faulty, you might want to install a manual gauge temporarily just too make sure, the other thing is it could be a blown headgasket, it is making too much cooling system pressure and it is venting and that is causing your sound.
Head gasket failure, exhaust gas exiting out into the cooling system, Replace head gasket, get it pressure checked for cracks and if good have it resurfaced and use new gaskets.
