White smoke from the exhaust is normally an indication of coolant entering the combustion chamber. Could be a blown head gasket or cracked head.
If the smoke is coming from the electric fan itself, then it needs replacing. It could be the smoke is steam that the fan is drawing from the radiator, and you have a coolant leak at the radiator.
A bad PCV valve can cause the engine to smoke. The valve is easy to change in most engines to correct the problem.
Look for a leak, if not white smoke from exhaust (going into engine)
No, any smoke is coming from the engine.No, any smoke is coming from the engine.
overheating of the engine.
It is very doubtful that it is smoke. It is most likely steam. Either there is a pinhole leak in the radiator allowing hot coolant to escape that then vaporizes into steam when it hits the atmosphere... or there is something spilled on the radiator that steams when the radiator gets hot. Have the radiator pressure tested for leaks.
Either another blown hose, or blown radiator. It could also be the antifreeze burning off of the engine.
Blue smoke is caused by engine oil being burnt by the engine.
Subaru 2.5 liter engine has a problem with head gaskets. If you have not had your head gaskets replaced, that is the first thing I would suspect.
You might have a blown head gasket or your engine block is cracked. Edit to add; The white smoke is steam. That means that your coolant got into your cylinders. A blown head gasket is the most likely cause, but a cracked engine block or warped aluminum heads are possibilities.
If you are getting exhaust smoke coming out of the radiator overflow, you need to replace the head gasket that seals the cylinder from the cylinder cap where your coolant runs through to cool the engine.
car overheats and produces steam/smoke. may crack engine block or head.
