Black smoke chevrolet - 2008 Chevrolet Colorado 2WD

Yes

I'm assuming you mean smoke from the exhaust pipe. That depends.....white smoke or black smoke? Black smoke = oil burning. That would be due to engine wear and mean internal work needed. White smoke = coolant. Impalas had problems with the lower intake gasket leaking internally or externally as a result of the DexCool coolant breaking down the gasket. Replacement of the intake gaskets is the fix for that problem.

A compression problem check the psi on each cyclinder
Most likely a ring problem if blue smoke (Replace rings)
White smoke gasket problems
Black smoke carbon build up
A rebuild job is in order( heads)

white smoke head gasket blue smoke engine internal black smoke fuel related

if its dark black smoke and the tip of the exhaust is pretty black the car is running rich, too much fuel is being used, needs a tune, if the smoke was white or grey its too lean, not enough fuel, if the smoke is blue its burning oil, id say the car just needs a tune or service.

is there ther diesel fuel in the oil? an injector may have gone out black smoke means to much fuel,

pump may need recalibrating or a kit through it
or you may have a cracked turbo

Black smoke is unburned gas. If the car is running fine besides the black smoke, it's most likely the Coolant Temperature Sensor. The part is roughly $20 and an easy fix.

PS- I'm guessing your check engine light is on...

if u got white smoke then you need an overhaul and if u got black smoke then check oxygen sensor and tune it
