Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello, Eddie here and I will do all I can to help. When you say "bleed the air out" Does the cooling system get air in it while the engine runs? Also, Does the coolant smell like fuel or have that combustion smell going on? Headgasket can leak between the combustion chamber and a coolant passage, so you may not notice an milkshake in the oil, and you may not notice any real smoke out the tailpipe either. A block test would confirm this, where coolant vapors are pulled into a test liquid, and if the liquid changes colors, (usually blue to yellow or green) that means hydrocarbons are in the coolant. Let us know. Thank you.
Alright I follow you, does it smell like combustion at all? like the oil dipstick is what it will kind of smell like sometimes when the head gasket has failed.
Take the radiator cap off of it, and smell the radiator cap. A block test is what you need really, but sometimes you can smell that combustion in the coolant.
If it's doing that, then I believe you will find it has blown a head gasket, overheating, coolant bubbling up out of the radiator as soon as it starts, that means air is getting into the coolant, and the only place it can get into the coolant at is the headgasket. I believe you will need a new headgasket to fix it. I hate to be the bearer of bad news there. But unfortunately you have all the symptoms of a blown headgasket.
Another way to tell, is if you can find a shop with a 4 gas analyzer like the old analyzers we used to use to inspect cars with when we stuck the sniffer in the tailpipe. Some shops have them, then you put the sniffer over the radiator cap open and you can read hydrocarbons in the coolant that way.
Alright, thank you. Best of luck with it.
