Sounds like your Head Gasket has gone bad, provided that smoke is coming from your exhaust. Replacing the Head Gasket is a major fix and should only be taken on by a more experienced person...
A way you can check is to open the cap on your radiator and start your car, after your car warms up and the thermostat opens the coolant level in the radiator should change. if you look in the radiator and see bubbles that's a problem and your head gaskets are bad. those bubbles are exhaust fumes that have leaked into the coolant system due to a bad head gasket.
If the smoke is coming from you engine compartment you could just have a leek in your coolant system and the coolant (anti freeze) is dripping on something hot and evaporating causing the smoke.
The car will over heat.
there might be a leak some where in a coolant line. or maybe you have a leak in your radiator.
if it is under the hood, it could be a small antifreeze or oil leak that when the engine is running the smoke is blown away, but when shut off it continues to burn off but is not blown away.
Antifreeze could be running out often due to a leak. It is important to inspect the radiator for small cracks or smoke.
It depends on how bad the leak is .If its a really bad leak to the point where the car is starting to overheat then no
You have to determine the source of the leak then decide on how to fix it.
cap is off
Internal engine antifreeze leak.
if the smoke is white and you've over heated the car in the past there is a good chance that you have blown the head gasket or even the heads sorry
it could be because you have an antifreeze leak and its just steam not smoke
The smoke is actually antifreeze mixed with air. The most common cause of this is a leaky heater core.
