White smoke out of car

What causes a car to emit large amount of white smoke? Why would my car is blowing out white smoke? What does it mean when a car blows 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. One reason for white smoke is very common and completely harmless. 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. White smoke can be a big problem or not, depending on the thickness.

The white smoke is the result of normal condensation which builds up inside the exhaust system. Internal combustion engines burn a mixture of air and gasoline to move the car. The afterburn gases consist of hydrocarbons which are harmful to the environment.

The good news is, white smoke alone is not an indicator of this problem. Along with the white smoke , you will be able to smell a sweet odor. Sometimes, you can also see that the coolant reservoir level is low. 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. 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. Regrettably, you may be faced with having to purchase a new engine.

When you start the car , the engine heats up, and these water droplets are emitted as white smoke. However, the white smoke persists it could mean that the coolant is leaking to the combustion chambers. A damaged head gasket or cracked engine block leak coolant.

If the smoke smells sweet or you detect the odor of antifreeze there could be a problem even if you do not see any white smoke. White Smoke 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. In some cases, the white smoke may be caused due to a deteriorated coolant in the radiator. If the coolant has run out , then it will lead to the engine overheating.

Another problem is when your car has a coolant leak. 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.

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. Condensation can turn to vapor, providing what looks like white exhaust.

But excessive white smoke likely means coolant is leaking into the engine combustion chambers. If you notice that your car is blowing white smoke. 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. 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.
