Have the cars cooling system tested at a reputable shop . The test you want to have done is a LEAK DOWN test which will give you a good idea where this problem is. Often this problem is due to a leaking head gasket.
You will notice the coolant reservoir level low with no signs of leakage, as the condition advances you may notice white, sweet smelling exhaust coming out the tail pipe and worse, engine coolant mixing with the engine oil.
catalytic converter converts some oxides to water, so water not a surprise in and of itself. Is there Antifreeze in your exhaust moisture? are you sure it is antifreeze? are you loosing coolant reservoir level at a measurable rate? Coolant only gets into exhaust by way of the cylinder head developing a leak. from the cooling jacket into the exhaust port of a cylinder. if it was leaking into the combustion chamber, you would have coolant in your oil, and the plug would be fouled with scale. possible to attempt a leak seal with K&N Metal Block Seal, if and ONLY if the leak is NOT into a combustion chamber. Or do the right thing and get the head repaired. Or, have your intake gaskets checked for leaks. On the 3.4 the intake gasket can leak coolant into the engine.
If your exhaust is getting in your coolant, you have a reeeeeeeeeeeeaaaaaaaaaaaaaaaaallllllllllllllllllyyyyyyyyyyyy major malfunction.
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.
If the coolant reservoir is low or empty, I would say you have a bad head gasket.
Bad head gasket? Oil mixing with coolant?
If you mean water expansion reservoir then a blown head gasket can allow exhaust gasses or oil to pass into the water jacket.
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
Sounds like bad head gasket.
No.
It is located under the Coolant reservoir. First remove the air intake filter box and boot, remember to remove the 2 wire harness attached to the box assembly. Looking underneath/behind the coolant reservoir you will see a 5/16 steel line stemming up from the exhaust manifold along side the head. You will need a 25mm wrench and a 16mm wrench to turn opposite each other. Remove the wire harness from the EPS. When removing the old sensor be careful not to damage the steel line. That's it!
