Q: Exhaust gases in coolant

asked by on February 11, 2016

I have exhaust gasses in the coolant.

Exhaust gas in the coolant usually means one thing a blown head gasket. If you look at the dipstick and see a milky substance in the oil then you have definitely blown your head gasket. I would recommend taking the vehicle to a shop to have the car fixed. If it is going to require removing the head, then it will probably need an entire rebuilding of the engine.
