Boiling Sound It's actually a 93 GS 300. My car is making a boiling/bubbling sound when I turn it off sometimes. The car is not flashing any lights or warnings that it is running hot. It is running just fine. What do you think?

It's probably excess coolant purging into the overflow tank, and if so, is nothing to worry about - that's what the overflow is meant for.

I smell antifreeze and when i turn off truck radiator bubbling


The bubbling sound in your radiator sounds like boiling water, An overheated engine. The smell is likely the vapors from the boiling water. Could have a blown head gasket or a cracked head as a result, but let it cool down for a couple of hours and check the coolant level, add if necessary and try it again If it doesn't bubble it should be ok

Coolant tank boiling


Look for a stuck closed thermostat first. Then make sure there is enough water in the radiator. Next look at the exhaust pipe. Is it black or a shade of tan? Is there steam coming from it when the engine is running? Compression gases getting into the water can mean a bad head gasket or worse a crack in the head or block.

Coolant bubbling in resevoir


I assume the coolant is not actually boiling and that the coolant is bubbling even when the engine is relatively cold. If so this would indicate a blown head gasket. Exhaust gases are escaping from a cylinder into the coolant passageways at the head gasket junction
