You have a blown head gasket. Open your radiator while the engine is running. You should find exhaust coming from it.
Usually the engine is burning coolant.
Could be getting into engine. Check tailpipe emissions for white smoke.
Vehicle likely overheated, or for some other reason, the head gasket has been breached, allowing coolant to be burned in the engine. The coolant is consumed, appearing as whitish smoke emitting from the tailpipe.
It could be transmission fluid or coolant, or a problem with the catalytic converter.
If you are getting white or grey smoke out of the tailpipe , especially when the engine is warmed up , you have coolant getting into an engine cylinder from a bad head gasket or warped or cracked cylinder head
Oil in coolant? Coolant in oil? Excessive white smoke from tailpipe when vehicle is at normal operating temperature? Engine miss or skip?
Coolant in the oil, low compression on the cylinder where the gasket is blown, air bubbles in the radiator, sweet smell at the tailpipe, white smoke at the tailpipe, especially at startup, & loosing coolant with no apparent leak.
white smoke out tailpipe.............coolant in engine oil looks like a chocolate milkshake
Sounds like you have a coolant leak.
Blown h20 seal in engine or turbo !!
your truck is likely leaking coolant due to a blown head gasket making white smoke and coolant smell
