Why does white smoke come out of my car AC?

The odorless, white steam or smoke coming out of your air conditioner is probably excess water stored in the heater box. Commonly, it is a sign of a restricted drain hole that needs cleaning. The steam or vapor collected during the process of condensation could have made its way out when the air hit it.

Accordingly, can I drive my car with white smoke?

White smoke. And if you drive a petrol car and see white smoke, it's really not good news. It could be that either the cylinder block or head are cracked, or that the head gasket is leaking. If the head gasket is not fixed immediately, it can spell the death of that engine.

Beside above, why does smoke come out of my car AC? Fog or smoke coming out the air vents is caused by cold dry air coming in contact with warmer, more moist air near the air conditioner. If the air temperature near the unit is below the dew point, this causes water vapor to form in the air and condense into water droplets, thus causing the fog or smoke.

Likewise, people ask, how do I fix white smoke from exhaust?

Follow these steps if your vehicle discharges an excessive amount of white steam:

  1. Inspect the intake gasket. An intake manifold evenly distributes the coolant or combustion mixture to each intake port in the cylinder heads.
  2. Examine further to check the head gasket.
  3. Look for any crack in the cylinder head.

Is white smoke from exhaust bad?

White smoke can be nothing to be concerned about if it's thin, like vapor. This is probably the result of normal condensation buildup inside the exhaust system. This kind of smoke disappears quickly. However, thicker smoke is a big problem, and can be caused the engine burning coolant.
