My car has white smoke coming out exhaust

Why is my car blowing white smoke? 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. What would cause white smoke? If white smoke continues to come out of your exhaust while the car is running, there are other issues at fault.

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. 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. 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. The truth of the matter is that there are a few things that can cause white smoke , but a blown head gasket is. When everything’s working properly, this exhaust is colorless. But if something is amiss, you’ll see a cloud of smoke coming out of the back of your car. Color can point to the cause of exhaust smoke.

As a car owner you expect something to come from the tailpipe. When I start my car for the first time every day, I have white smoke come out my exhaust usually for about a minute or two but it runs fine after that. If you see white smoke coming out of the tailpipe, that smoke means that your car has a leaking cylinder-head gasket or a cracked head gasket. If there is just a leak in the gasket, the problem should be relatively easy and inexpensive to fix, but if the problem is a cracked head gasket, chances are the repair will be a lot more complicated and expensive. However, it can also indicate a more serious issue if the coolant or gas is the moisture being burned off.

If the smoke disappears shortly after starting, there is likely no problem, but if it continues, it means that water or coolant are in the combustion chamber. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. White smoke is caused by coolant or water coming out the tail pipe.

Keep an eye on the coolant level in the radiator in any event. Let us know how it goes or if the problem persists. If white smoke starts to escape immediately, water begins to drip as the car warms up, and your exhaust smells of antifreeze, there is a coolant leak inside your engine.

Perform two final checks by opening your radiator (when cool) and look for oil floating on the water, and pulling your dipstick and looking for a milky emulsion (antifreeze mixed with the oil) on it. Lots of white exhaust smoke on start up is usually a sign of a head gasket problem. If the leak is very small, or leaking into adjacent cylinders, there may not be much smoke upon starting up, and yet still enough coolant may be pulled into the combustion chamber(s) to produce a strong sweetish exhaust smell. Lots of Blue Smoke When Starting Cars (not Diesel): Bad Valve Seals. If you see blue smoke coming out of exhaust after you have parked your car for a while and the engine is not a diesel, the probable culprit is Bad Valve Seals.

It should reduce or even disappear after the car becomes reasonably warm. 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. When you park your car under extremely cold conditions, the car becomes too cool, its air shrinks and starts producing moisture. Open the hood and check for any noticeable coolant leaks.

The car has a strong order of raw fuel and is blowing white smoke out of the tailpipe, and the stutter is strong enough to shake the steering wheel. The white smoke is the result of normal condensation which build up inside the exhaust system. This kind of smoke disappears quickly.

However, thicker smoke is a big problem, and can be caused the engine burning coolant.
