Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating.
What does white smoke from the tailpipe usually indicate?

Bad head gasket symptoms
- White smoke coming from the tailpipe.

- Milky white coloration in the oil.
- Engine overheating.
Can bad spark plugs cause smoke?
Spark plugs will not cause the motor to smoke, good or bad. Whitish gray smoke sounds like a fueling problem.
Can bad gas cause white smoke?
The fuel injector is responsible for injecting fuel into the internal combustion chamber at the exact right time. If you were to have a bad fuel injector, then it would cause white smoke to form because the proper amount of fuel did not enter the chamber at the right time.
Is it safe to drive a smoking car?
It depends on the source of the smoke. If the smoke is from engine oil dripping onto a hot exhaust manifold, you could end up with an engine fire. Smoke is serious so the bottom line is unless you know exactly why it’s smoking there is no other prudent course but to just not drive the vehicle until it’s repaired.
Can low oil cause smoke?
Generally, blue smoke is caused by oil seeping into the engine and being burned along with the fuel. Your engine will be low on oil, as well. Note that if the exhaust is grayish, it is more likely to be caused by an incorrect fuel-to-air ratio, as your engine is burning “rich” – too much fuel is being combusted.
What causes engine to smoke on startup?
Usually it’s due to worn piston rings or wear on the cylinders themselves. The valves sit right on top of the cylinders and when the seals are worn out, oil leaks into the combustion chambers and burns together with the fuel. Sometimes after a car has been parked for a while, blue smoke is noticeable on start up.
