What could be the problem with a 2001 22 L Sunfire that has a burnt oil smell at startup and idle but no smoke in the exhaust and an increase in coolant temp of approx 10 degrees?

You probably have an oil leak somewhere around the top of the engine. Valve cover gasket, leaking head gasket. When the engine warms up, it cooks it off and you smell it. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info

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

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.

Bad head gasket? Oil mixing with coolant?

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.

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.

User Avatar

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

User Avatar

Sounds like bad head gasket.

User Avatar

headgasket leak and exhaust gas is getting into the coolant

User Avatar

Exhaust system. Usually manifold near port(s).

User Avatar

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.

User Avatar

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.

User Avatar

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.

Not necessarily, adding duel exhaust will not increase the performance of a mower. It would require the exhaust port to be bigger and require a bigger pipe to be used.

User Avatar

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.

User Avatar

it makes you exhaust louder or " meaner " and some say it causes an increase in horsepower
