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.
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.
Can you have black smoke and white smoke?
A: Yes. Besides white smoke, you can have black smoke, blue smoke, and gray smoke. Each of these colors indicates a different kind of problem. Black smoke indicates that gasoline has flooded the combustion chamber instead of the coolant that causes white smoke.
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 do I have white smoke coming from my radiator?
Make sure you are monitoring the coolant level in the radiator/reservoir. If the white smoke is exclusively from the exhaust pipe, a leaking cylinder head gasket would be a suspect. In this case the coolant would end up being heated in the combustion chambers and blown out the exhaust as the engine starts.
