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.
The smoke may be because you are overheating the engine. There are several causes for this. Check your fluid level in your radiator. Make sure it is full. Check your thermostat. Change it if it is weak. Check your radiator cap. This needs to be the correct one for the engine. Check all moving parts for your water system. Like the water pump, hoses and fittings.
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.
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.
overheating of the engine.
Blue smoke is caused by engine oil being burnt by the engine.
Either another blown hose, or blown radiator. It could also be the antifreeze burning off of the engine.
If you nicked the oil pan it could cause it to smoke from engine area. Is the smoke coming from the exhaust or engine bay? If exhaust, then I highly doubt it was caused by the curb incident.
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.
Your water pump might be broken or your thermostat might need to be replaced. You obviously don't have a leak so somehow the fluid isn't moving through the engine. If the thermostat is broken it will not let fluid into the engine and then the engine will overheat and the radiator will release smoke.
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.
car overheats and produces steam/smoke. may crack engine block or head.
This engine could have burnt rings in it. There also could be an old leak which is running down on the manifold which would cause the engine to smoke.
The main cause of motorbike smoke is when the diesel is being burned and used in the engine. This smoke causes pollution to the environment.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
leaking head gasket
when it get really humid or very cold
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.
Not usually. If the rocker arms are loose because the cam lobes are worn down, that could be an indication of a worn engine, which might have bad rings or loose valve guides, which would cause an engine to smoke.
This is not that uncommon. Some oil is so hot that it will start to smoke. The smoke can escape through this opening to the engine.
That smoke is steam. You have a leak in the radiator or a hose. Take it to a mechanic.
Moisture in the exhaust, or a cold running engine.
