Blue smoke at startup, that clears up within a few minutes is normally cause by worn valve seals. Blue smoke that continues is oil burning. Black smoke is fuel burning from an overly rich fuel mixture. White smoke is normal at startup, especially during the winter, but if it does not dissipate rapidly, it can be a sign of coolant entering the combustion chamber. If it is coolant, it will smell sweet, you will be loosing coolant, and this is a sign of serious trouble. Usually a blown head gasket or cracked/warped head. First is what you call smoke BLUE, BLACK, or like FOG or STEAM ??? Black smoke usually fuel Blue smoke usually oil Steam/Fog usually water or coolant Now , the big question is whats the cause? Flooding fuel injector?, Worn piston rings?, Blown head gaskets?
in the exhaust system
Look on the exhaust pipe ahead of the catalytic convertor for a spark plug sized sensor screwed into the pipe. On a 1988 Cheyenne it is located on the left side of the engine on the exhaust manifold.
It should have 2 and they are screewed into the exhaust system/Pipes.
where is the transmission censor located on a 1997 Chevy cheyenne truck
A Chevy Cheyenne and Silverado are the same its just that they changed the name in Mexico from Silverado to Cheyenne
Sounds like a head gasket problem. Better run a compression check.
Yep
I believe 1998 was the last year for the cheyenne option package.
most 88-98 Chevy pickups are basically the same. the only difference between yhe cheyenne and silverado is the trim.
Cheyenne is a designation of a trim level that is the next step up from w/t.
GMC Sierra
What engine?
