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.
Sounds like a sticking thermostat. When you say "the engine isn't hot", you mean "the radiator isn't hot", right? Because if the temperature gauge says overheating, your engine ishot
Blown head gasket.
look for antifreeze coming out of the radiator as the engine warms up after a cold start.
Consider replacing your radiator cap . .
Check your heater hoses, that's where the water ciruclates into the heater from the water pump.
That smoke is steam. You have a leak in the radiator or a hose. Take it to a mechanic.
The coolant is pumped from the thermostat housing into the top of the radiator but not until the thermostat opens.
you should find it attached to the radiator & the water pump. if it is missing, that's where you should put the new one. radiator at the front of the vehicle, engine behind it, water pump on front of engine, with hose, or short metal tube coming out of the bottom of it. the radiator will also have a hose or short metal tube coming out of the bottom of it also,(the radiator should also have another hose coming from it at the top)
Remove the bottom radiator hose. Put a garden hose into the top of the radiator. Allow the garden hose to run until the water coming out of the bottom of the radiator is clear.
no, they are not related. tiny bubbles that make the radiator "foam up" is the result of exhaust gas leaking into the radiator. causes are blown head gasket, cracked cylinder head or cracked block. hth
heater core needs replacement
appearance, reappearance, coming, replacement, reaction
Drain the radiator. Leaving the drain plug open, run water from a hose into the radiator and continue to flush until the out coming water is clear.
If there are lines coming from the transmission to the radiator, it has a cooler in the radiator. If there are lines from the transmission to an external heat exchanger, that would be an auxiliary cooler.
because there is a crack in you engine and its runing over in to it
Overheating due to coolant going to the reservoir and not coming back to the radiator because of the bad cap.
your thermostat is inline with your radiator.. its in a junction coming off the bottom radiator three hoses plug into it.
easiest way is to fill radiator and look and see where fluid is coming out, but Im sure you thought of that. The best way is to plug the ends of the radiator up with some type of rubber stopper then insert blow air through the drainport while holding it under water. Wherever the bubbles are coming from is where its leaking.
no,their must be a leak inside your radiator where the trans lines are screwed in. The water in the radiator is to help keep trans fluid that passes thru radiator cool. should have no water coming out of trans lines.
Open the radiator drain and let drain into a catch basin. Run water through the radiator by filling through the radiator cap with a hose till the water coming out is clear. Fill through the overflow bottle if there is not a radiator cap present.
There are two major signs that the car radiator is broken. One sign is that the radiator will not hold fluid. Another sign is that there is smoke coming from under the hood of the car.
Find where the fluid is coming out and repair/replace it.
Bad thermostat, fans not working or coming on when they are supposed to, bad waterpump, bad radiator or radiator cap.
