White smoke from truck exhaust

In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time. First is normal condition (so you don’t have to panic ) and the second is a not so normal condition which should be fixed as soon as possible. The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating.

A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. If the white smoke coming out is in volumes, you should stop the car immediately and call for emergency roadside assistance, including a tow truck. Heavy volume of white smoke means the engine is dangerously overheating. This kind of smoke disappears.

Why is there white smoke coming out of my exhaust? What does black, blue or white smoke from exhaust mean? The engine will burn oil when oil reaches the combustion chamber.

The combustion chamber is the air space between the bottom of the cylinder head and the top of each piston. If your truck is a diesel and produces white smoke while warming up, this is completely normal. Diesel trucks also produce smoke during the cleaning exhaust filter operation.

If this is the case, there is nothing wrong with your truck. Some white exhaust smoke is normal, especially when you first start the car. But excessive white smoke likely means coolant is leaking into the engine combustion chambers.

Condensation can turn to vapor, providing what looks like white exhaust. Smoke clears up while driving and does not reappear while stopped and idling (like stopped at a light). If I park for a few minutes then, come back and start it white smoke reappears until i start driving. You can smell the coolant in the exhaust.

If it is doing it on start up,you probably have a deterioating head gasket. IT usually one of the corner cylinders if the engine has not been overheated)It allows coolant to seep into cylinder ever so slightly and on start up burns up thru exhaust. You may commonly see white smoke coming from the exhaust on cooler days upon starting. Also it stalls when Idle.

My car has an automatic transmission. I can tell you exactly what causes the white smoke. The most common reason for white smoke from the exhaust pipe that is condensed in the exhaust pipe. Steam is emitted by condensation in exhaust pipe which is seen at exhaust emission. It sounds like you have coolant coming out the tail pipe as well.

You have internal engine damage. White smoke is a result of burning coolant. It may be a head gasket but needs to be confirmed. A shop can do this by performing a leak down test on each cylinder to determine if a gasket has failed.

Last week we got fuel from a brand new place and the next day while unloading (hopper bottom) there was a lot of white smoke coming from the exhaust. It was a cold morning so I thought it was starting to gel up. When I left it smoked real bad but ran great. The smoke escaping from your tailpipe is actually steam and will appear more gray than white in color if examined closely.

The water is the result of an accumulation of that same steam as it makes its way through the exhaust system and out of the tailpipe where it condenses from its gas form back into liquid. Depending on the moisture content in the air, the white smoke could be condensation being burned in the exhaust , or in the cats.
