You may commonly see white smoke coming from the exhaust on cooler days upon starting. WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include Faulty or damaged injectors Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway).

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. As this continues, the white smoke will begin to have a sweet odor smell that won’t go away.
