What is causing thick white smoke from exhaust Geo Tracker?
Thick white smoke is caused when coolant gets into a cylinder and from there into the exhaust. It is a sign that if it is not fixed real soon, you will blow or burn up your engine.
Why is there still white smoke coming from your exhaust of a 1993 Mitsubishi Diamante when you just had the engine replaced?
Typically, white smoke after sitting over night is just steam from condensation or moisture in the air. However, thick white smoke while at operating temp is an indication that you are burning anti-freeze. You may have a blown head gasket if this is the case. Over filling oil can cause a white/blue smoke as well.
