your truck is likely leaking coolant due to a blown head gasket making white smoke and coolant smell
Losing coolant with no apparent leaks, White smoke out the exhaust that has a sweet smell to it,
white smoke from coolant usually indicates oil in coolant,this usually means a blown headgasket
White smoke indicates coolant burning, usually accompanied by a sweet smell. It is possible to have a blown gasket and have no coolant in the oil, the leak is probably only present while the coolant system is under pressure and all of it is being burned in combustion.
Most likely wore piston rings or valve seals. Answer 2: It's really common it's a leaking/cracked head gasket. White smoke is often caused by coolant entering the combustion chamber. So check ur coolant levels and even smell the smoke to see if it smells like evapourated coolant (a dirty water sort of smell).
The main part of diesel fuel is kerosene, which produces thick black smoke, and gives that smell that is commonly associated with diesel. most likely if it is white smoke, it is antifreeze, if it has a blue tint to it, it is oil. the smell of burnt diesel is rather strong so it could cancel the burnt oil smell, or on the other hand it could be coolant, because burned coolant doesn't have a strong smell. I would check your coolant and oil levels, and check your coolant for having oil in it.
Engine oil mixing with coolant and/or coolant mixing with engine oil.Losing coolant but don't see any leaks. White smoke (steam) coming out the exhaust that has a sweet smell to it.
White smoke. Means water/coolant in your engine. Most likely you blew the head gasket, if you smell oil and see white smoke.
is there a sweet smell? Does the coolant level drop in the overflow tank and/or the radiator? if so, you might be looking at a bad head gasket. if there is slight white smoke(usually condensation) and no loss of coolant, then it is normal. once the engine (and exhaust system) gets hot, there should be no more smoke.
White smoke indicates a blown head gasket, the smoke is coolant burning
White smoke coming from your tail pipe often indicates an issue with your coolant. The smoke comes from burning coolant. The engine sputters and white smoke is likely an issue with the head gasket.
Check the coolant level. Is there a sweet smell to the white smoke from the exhaust? Sounds like either a blown head gasket or a cracked head.
