White smoke coolant leak

In this case the coolant would end up being heated in the combustion chambers and blown. 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. Coolant leaks When the coolant is heated up, it will produce white smoke. The most common cause of white smoke from the engine bay is a coolant leak that is leaking on a heated part like the exhaust manifold. Open the hood and check for any noticeable coolant leaks.

Excessive White Smoke From Exhaust When the smoke emitted is thick, white and billowing, this usually points to a crack somewhere within the internal combustion engine which is allowing coolant or oil to leak out of the areas they should be contained within. The coolant is then being burne producing the thick white smoke. 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. 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.

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. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Check the brake fluid level in the brake master cylinder. The seal in the master cylinder can leak brake fluid into the brake booster. The vacuum hose to the brake booster can then suck the brake fluid from the brake booster into the engine where it burns and causes a white smoke out of the exhaust.

My car started blowing lots of white smoke out of the exhaust and I started having. 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.

Suggest for the sake of your wallet to not start or drive the car until you have someone knowledgeable take a look at what’s going on. The indication is apparent when white smoke appears while the car is running, but not when you start it. The reason for this type of white smoke is due to burning coolant that somehow got mixed up. If you are losing coolant out of the degas, then you may well have a bad EGR cooler.

A bad EGR cooler will also cause white smoke. A few days ago I noticed my coolant tank was almost empty, so I know there is a leak somewhere and I believe the coolant is what is burning and causing the smell and smoke. No problems, no noticeable leaks , no coolant loss.

Left car sit until tonight. I cleaned up the only coolant I still saw, puddle under intake manifold. Took car for minute drive, no problems, until I was backing into the garage.

Then white smoke from exhaust and under the hoo no smell this time, and a lot less smoke than last time. If the white smoke is coming from the engine compartment, then you are leaking coolant from radiator, hose or gasket. It usually leaks on the exhaust manifold and produces white or grayish smoke with a sweet odor.

You can check the same under the hood. Once that happens, the oil will become contaminated. The first sign of having contaminated oil is white exhaust smoke coming out of the tailpipe.

As this continues, the white smoke will begin to have a sweet odor smell that won’t go away. Mercrusier 4MPI with approx 7hours. Recently I noticed white smoke with a smell of coolant. This happens when I start the engine not necessarily after running. Also small oil seepage from corner of gasket on hea only very slight seep and no coolant leaking anywhere.

If the smoke is from the engine, then pressure testing the cooling system for leaks may locate the leak. I then noticed white smoke coming from under the hoo and as I went to pull the car off the road the engine died. Now today I picked my car up and added some coolant , hoping it was a simple hose leak.

Also, if the leak is large enough, you may get water in your oil as the coolant seeps past your piston rings or if there is a gap in the gasket between an oil passage and the water jacket. The color of the oil on the dipstick also looks normal. No unusual noises in the engine compartment. Sometimes, white smoke coming out from your car exhaust may also indicate a coolant leak. With the car still on, listen to any humming sound that might be coming from the front part of your car.

If your radiator system has a coolant leak , then you will be able to hear some sound coming from this part.
