Q: 6.0 powerstroke blowing white smoke on start up and coolent Reservoir keeps going empty after three weeks

asked by on

6.0 keeps blowing white smoke on start up and coolant Reservoir goes empty after about three weeks it runs perfect but I want to make sure it isn't something major wrong with it

My car has 2300000 miles.
My car has an automatic transmission.

Hi there. What you are describing is an indication of a coolant leak inside the motor. Typically this is a major issue caused by a blown head gasket. When oil and coolant mix together, white smoke is typically expelled out of the exhaust. The best way to verify this is to check your oil on the dipstick. If it is milky or foamy, then unfortunately, this is a major repair that will need to be fixed by a professional engine repair facility.
