you have a leak in a hose or your radiator itself. Look for antifreeze dripping from under car while engine is running and hot enough for the fan to kick on.
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.
That smoke is steam. You have a leak in the radiator or a hose. Take it to a mechanic.
the engine will overheat!for a start ,and the dash water temperature light will come on!there will be steam coming from the radiator...
It is so cold that steam is coming of it.
A bad heater core / it needs to be replaced
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
Well if you get a box with purple steam coming out of it as a gift flying around the screen, then its a Piece of Cloud. But originally there is no box like that!Fizzysweete
Steam radiator valves should always be fully open, or fully closed. Steam enters the radiator from the boiler, and fills the radiator. The air vent shuts, having sensed moisture inside the radiator. The steam then cools, condenses to water, and drains from the radiator. If you leave a valve partially open, then the steam enters easily, because of the pressure. But, the water has a difficult time draining, so the radiator can collect it, and steals it from the furnace, which needs it for resupply.
Cooling system leak or engine overheating and steam escaping from the radiator cap.Cooling system leak or engine overheating and steam escaping from the radiator cap.
It's steam from boiling coolant (or water) coming out of the overflow hose connected to the top of the radiator just below the level of the cap.
There are plenty of ways a car can break down without the radiator being a part of the cause. As for the reason you'd see steam from a radiator, it would escape if there was a leak in the radiator or the hoses, or if the cap was opened. The contents in a radiator are very hot - hot enough to produce steam.
That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
