One of two conditions is responsible for white smoke blowing out of your exhaust. 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. If you the white smoke consistently comes out and the sweet odor smell is present, then it is definitely a problem with your coolant leaking. In transmission fluid case, the engine is sucking the fluid through a vacuum hose, which leads to the color white from smoke.
The exhaust will also have a burned oil smell. One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant , it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust. 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. In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector.
Now this isn’t always the case, but after some trouble shooting we’re usually the go-to shop when diesel drivers need refurbishe rebuilt, or new injectors.
