Q: White smoke comes out of Tailpipe.

asked by on

There is white smoke coming out of the tailpipe, and the car is sluggish when switching gears.

The combustion process gives off a small amount of water, so the white smoke could be from condensation in hot exhaust gases, particularly in cold weather.

In extreme cases, a head gasket rupture causes coolant to leak into the engine (often accompanied by a "sweet" smell) causing thick clouds of white smoke to spew. Coolant in the engine inhibits some performance, which may explain the lack of power.

I would suggest hiring a trained technician, like the ones at YourMechanic, to run a diagnostic to determine the source and cause of the white exhaust smoke, and recommend any necessary repairs.
