Why is white smoke coming out of my exhaust pipe?
If you continue to see white smoke coming out of the pipe after the engine has had a chance to warm up or while accelerating, then your coolant might be leaking internally. 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.
Why is my car blowing black smoke when I accelerate?
If your vehicle is emitting black smoke from the exhaust, it means that the engine is getting more fuel than air. A correct fuel-to-air ratio is necessary for an engine to operate normally. White smoke on the other hand is associated with engine burning coolant.
Where does the white smoke come from in a car?
The best way is to check inside your cylinders and spark plugs. If the car is combusting coolant, it will clean the cylinders. So if no of the cylinders is cleaned, but the car is still burning coolant, it must come from after the combustion chambers, like from the EGR cooler.
What does white smoke from a diesel engine mean?
Broken Fuel Pumping Injection. If you have a diesel car, then diesel white smoke indicates that the fuel pumping injection timing has stopped working. This pump is responsible for pumping diesel into the cylinders of a diesel engine.
Why does my car have white smoke coming from the exhaust?
The main cause of smoke from exhaust when accelerating is due to a burning coolant or transmission fluid problem. When the white smoke is as a result of transmission fluid, it means that the car engine is likely absorbing excess fluid from the vacuum pipe or hose which is what makes it produce white smoke.

Why is white smoke coming out of the tailpipe?
If the problem is with transmission fluid, it means that the engine is taking fuel through a hosepipe, and this is what leads to white smoke coming out of the tailpipe when you press on the pedal. One way to identify this problem is you will get a burned oil smell every time you accelerate.
Is it possible for a fuel filter to produce white smoke?
Yes. If the fuel is contaminated with water or some other foreign material it is possible that it will produce white smoke. The best way to test the fuel is to pull the filter and put it in a clear glass. Wait a few minutes and see if there is any separation. Can air in fuel cause white smoke? Yes. This is another common cause of white smoke.
Another cause of white smoke is leaking coolant. The leakage will be noticeable when the smoke is visible while driving the car. Furthermore, there will also be a sweet smell coming out of the exhaust pipe. Don’t let this fool you as the sweet smell is a cause for concern.
Why does my car have a white smoke smell?
If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell. In this situation, you can pressure test the cooling system if the coolant is low or the engine has been overheating. If it does not, your vehicle is mostly having a leaking gasket.
Why does the exhaust smell like burnt oil?
The exhaust will also have a burned oil smell. If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell. In this situation, you can pressure test the cooling system if the coolant is low or the engine has been overheating.
What causes the smoke to come out of the tailpipe?
If oil were to ever leak out of your piston rings or valve seals, then it would flow into the internal combustion chamber along with the fuel. Once the fuel and oil get mixed together, it will cause to come out of the tailpipe. The color of the smoke will actually be blue-ish but it will appear to be white smoke to some people.
Why do I have white smoke coming from my exhaust pipe?
White smoke from the exhaust pipe on startup, idle, or acceleration tells us that coolant or water is getting vaporized in the exhaust pipe. You can also carefully smell the water or smoke from the exhaust; if it smells sweet, it’s most likely coolant, and in this case, you have a bigger problem.

Why does my exhaust have a sweet smell?
Internal coolant leakage is another cause of white exhaust smoke. In the introduction to this section we mentioned that when the coolant leaks into the combustion chamber, the white smoke produced has a sweet smell.
What to do if your exhaust pipe is leaking?
If you suspect that your EGR cooler is faulty, you may have to get help from a mechanic to diagnose it properly. The best way is to use a coolant leak tester and to take the EGR pipes off to see if you can see any coolant is entering the exhaust pipe. 3. Bad Head Gasket/Cracked Cylinder Head
