coolant from exhaust indicates a blown headgasket or a cracked head on the engine. be sure that it is coolant and not just condensation coming from exhaust before you do repairs
Defective exhaust system.
In a 2004 Pontiac Sunfire, there are two oxygen sensors. One would be located in the exhaust before the catalytic converter. The other is located in the exhaust after the catalytic converter.
The price for a new exhaust system for a 1995 Pontiac Sunfire is between $110 and $253, depending on the brand chosen. The MagnaFlow is one of the more expensive brands.
If your exhaust is getting in your coolant, you have a reeeeeeeeeeeeaaaaaaaaaaaaaaaaallllllllllllllllllyyyyyyyyyyyy major malfunction.
An increase in cabin noise caused by the exhaust.
A blown head gasket could allow coolant to enter the combustion chamber from the water jacket. The coolant probably is running out the exhaust on first start-up. More often, you will notice the coolant being pumped out of the overflow as the exhaust gas pressurizes the coolant. You should look for this symptom when the engine warms up. Coolant in the exhaust on start-up and then the coolant overpressure overflow from the expansion tank or radiator happening together is almost sure indication of the head gasket failure.
I'm assuming your asking about the coolant purge valve, there is a pipe that runs right above the exhaust manifold, take a 6mm socket and turn c/clockwise half a turn while you are filling the coolant. Ahen coolant comes out, system is purged. Idle for 20 mins and observe temp and coolant level anyways, cause overheating those engines is not cool at all.
Bad head gasket? Oil mixing with coolant?
it sounds like your coolant over flow tank is leaking. it is a common problem with these cars. might also check your radiator for leaks or your exhaust for coolant, but if there is coolant in your exhaust that would mean blown heads
The temperature range of a car exhaust ranges from 500 to 700 degrees Fahrenheit. An airplane exhaust can reach temperatures of 1200 to 1400 degrees.
Sounds like bad head gasket.
headgasket leak and exhaust gas is getting into the coolant
Exhaust system. Usually manifold near port(s).
The upstream oxygen sensor is mounted in the exhaust manifold The downstream oxygen sensor is mounted in the exhaust pipe after the catalytic converter
Coolant leaking out from exhaust is bad news, probably a cracked head or bad head gasket or both. Be sure it is coolant that is leaking and not just plain water. Plain water is normal to drip out the exhaust, it's caused by condensation.
1) Your engine is overheating and the coolant is boiling. Or 2) Exhaust is leaking into the coolant, probably through a bad head gasket or cracked head.
You need a special tester called a block check. You fill it with a special fluid and then use it to suck fumes out of the radiator . if the fluid turns yellow it means there is exhaust gasses in the coolant.
If you are only leaking coolant into the exhaust and use the type with copper in it, then yes, it should stop the leak. If coolant is getting into the oil or exhaust is getting into the radiator then no, none of them will do any good.
Coolant getting into the fuel or oil.
The head gasket is blown.
If the smoke is coming from the exhaust then it's coolant. If its not turning over then it could be hydrolocked from a coolant leak.
Exhaust temperatures on a motorcycle can reach as high as 800f.
