White smoke coming from car engine

Why would a car blow white smoke? What can cause white smoke to come out of exhaust? Why is white smoke coming from the hood of my car? What causes excessive white smoke from a diesel engine?

Leaking coolant is a leading cause for white smoke coming from the engine. The cooling system flows from the radiator to the engine block. Begin by checking coolant levels in the radiator. 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.

Then after about seconds to a minute, the white smoke should clear up. If this is the case then you have nothing to worry about. The oil filler cap in almost all the engines releases a faint whiff of smoke , which is a residue of the burnt fuel inside the engine. Older engines produce more hot spots, which make the car smoking under hood but not overheating.

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. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke ( steam ) is no longer seen.

Cars on a cold morning in the winter are going to generate a white vapor. This ordinarily goes away once the car engine is warm. If the white smoke still keeps coming out after the engine is nice and warm something may be wrong. There may be problems with the engine block , and coolant may be leaking in to the engine because of a leak in the head gasket.

Coolant is entering the cylinder and is being burned along with fuel. White smoke= blown cylinder head gasket. Over time your volume of engine coolant decreases hence the reason the reason you are refilling every few days. Also change the oil as well as you might coolant in the oil as well. You may commonly see white smoke coming from the exhaust on cooler days upon starting.

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. The white smoke could have been steam from a coolant leak. I’ve had that happen twice, one time on a Corolla due to a radiator that sprang a leak, and the other time on a Ford truck, a coolant hose burst.

My coolant seemed really low and he added some and I went on my way. With your engine being a V there is a. If your engine puffs out an occasional stream of white smoke , it could be steam coming from your coolant overflow tank. Leaking and burning transmission fluid and power steering fluid will also create a cloud of smoke similar to an engine oil leak, but with a slightly more chemical aroma.

Smoke rarely comes from the engine bay, and if it does, the issue is typically critical already.
