    Did you not have dexcool in before ?

    Regardless of the type of coolant, (even if you used gator aide) would not have anything to do with what is coming out of the exhaust unless you have either a cracked cylinder head or a blown cylinder head gasket. You need to have the system pressure tested and possibly have a cylinder leakdown or compression test done. If you find any coolant in the engine oil do not run the engine.

Dexcool antifreeze cannot be mixed with any other antifreeze except the new all makes all models antifreeze. If you mixed it with green or any other antifreeze it becomes toxic & will eat away from the inside out. Try flushing it all out, but it sounds like you blew a head gasket & may have hurt other cooling system components.

Hi there i have a 1997 Nissan Hardbody 1 tonner 2.7 turbo diesel it is pushing oil through the exhaust and its blowing white smoke what could be the cause ?

You probably need a new head gasket and other gaskets. Oil and probably anti-freeze are leaking in to the engine works. The white smoke is almost always caused by anti-freeze.

05 Nissan Altima 4.2l replaced valve cover, gasket, and spark plugs looks fine with no leaks and engine runs fine,now I have lots of white smoke at start up which goes away once engine is warm.

White smoke indicates water going through your engine or condensation in your exhaust. If it is a lot of smoke you probably have a small leak in your head gasket that seals back up as the engine warms and the materials expand. It will get worse as time goes on. If it's just a little smoke that doesn't last long it's probably condensation in your exhaust, especially if it's cold outside. Condensation is caused by the air cooling down in your exhaust after you shut down the engine.

03 nissan altima has white steam always coming from the exhaust pipe. car runs and drives good. just dont know while it always steaming like it still winter.

Could be oil smoke, it's white with a slight blue tint. If the engine was not properly maintained or abused, the piston rings can wear. Worn piston rings might allow oil from the crankcase to pass into the combustion chamber; there, it will be burned and pushed out the exhaust.

Smoking exhaust ( thick smoke)

More then likely the muffler and the catalytic converter is full of oil give it some time it may clear out. Good luck.

Loosing power white smoke

white smoke is caused by water entering or anti-freeze entering cylinder. if in radiator or recovery tank, it will look like a chocalate milkshake. check on oil dipstick for traces of water or anti-freeze. possible causes, head gasket, intake gasket, etc. check close for a bad gasket.

White smoke from exhaust

Is the car sluggish at high speeds? If so, your head gasket might have gone out.

Fill up your overflow bottle to the full mark and check the coolant level in about 5 days.(drive it normally as if nothing is going on) If the level is down, your head gasket is gone. How about the check engine light , is it on?? post results.
