Car overheated white smoke

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. White smoke : Water condensation or antifreeze has mixed with the fuel supply. 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. If smoke is being release then this is indicative of a problem. HOWTO looks at all the possible reasons why white smoke is coming from your exhaust pipe. The white smoke and overheating is usually a sign of a blown cylinder head gasket. When the car overheats for an extended period of time or is low on coolant (causing the temperature to rise), the severe heat can cause the cylinder head gasket to become compromised which causes oil to leak into the coolant and water to leak into the engine.

When I was driving home, there were tons of white smoke coming from the rear. The car already failed smog test and about to retire. You said white smoke was coming out from the hood area behind the engine: You could have a leaked manifold gasket.

The cause could be a faulty water pump If the pump is not working well the coolant and or water is not being forced through the system well enough to keep the engine cooled thus creating overheat. You are making a serious mistake by waiting. 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. My car started blowing lots of white smoke out of the exhaust and I started having. 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. 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. Is there white smoke coming from the exhaust and is the car idling poorly? If so, coolant may be getting into the combustion chamber. On cold winter days, it is common to see white smoke from exhaust pipe as soon as you start the car.

With the car cooled down, it may be driven to a convenient place and examined for damage. If the car begins to run hot again, shut it down and have it towed. Does the car still run?

That is always a good sign. Cars that have electronic systems will automatically lose power and come to a complete stop when the temperature gets too high. Your problem is one of them.

If the smoke is blue and comes from the exhaust, you have an internal oil leak. If you find yourself checking the level and adding fluid on a regular basis, something is amiss. You may also find that your car has been overheating.

This overheating is caused by the coolant leaking into the fuel, and it may manifest itself long before you see your first whiff of white smoke from the tailpipe. I checked and my fan doesnt come on. Have you checked for a leak in the cooling system? Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.

One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating. When that happens, the coolant could overheat and cause the car to shut down. Smoke can also come from an electrical system malfunction, serpentine or drive belt that is damaged or electrical wires. If the engine is not overheating or the car is not having any symptoms, like running rough, it is probably a good idea to have a professional mechanic come to your location and complete a smoke coming from engine inspection. What does WHITE smoke from my exhaust mean?

Even a small leak in the coolant can lead to overheating and serious risk of. I thought it was the excess water that had gotten onto the engine that was now boiling away. The next day, I started the car but it ran very rough, like it was misfiring, and then it died.
