If this happens only when engine is cold it is a normal condition If this hasppens when engine is at normal operating temperature it may be a sign of head gasket leakage Check to see if oil is getting into coolant or coolant getting mixed with engine oil
Clear or blackish water coming from exhaust is very common and is nothing more than condensation from the metal heating up. If you have white smoke with a sweet smell then you may have an issue, but I think your fine and just seeing condensation.
Leak in exhaust system perhaps exhaust manifold being sucked in through air intake (grid at lower end of windshield)
Oxygen sensor
1-2 located by the exhaust manifold
on the rear exhaust manifold hard to get to
Check your coolant level.
U have a blown head gasket,cracked cylinder head or cracked block.. The white smoke is from water getting into the Exhaust system.
Two. One on the bottom of the exhaust manifold and one after the catalytic converter on the exhaust system.
A 2002 Chevy Cavalier 2.2 liter has a total of 1 oxygen sensor located in the exhaust manifold. It constantly monitors oxygen levels in the exhaust to allow the computer to make mixture adjustments.
There are 2...On the exhaust manifold and after the cat. converter
Removing the exhaust from a 2002 Cavalier is not too hard as long as no bolts are rusted. Start by unbolting the exhaust at the engine. Remove all exhaust clamps. Unbolt the pipe joints and pull the sections from under the car.
That would be the O2 sensor located in the exhaust system after the catalytic converter.
