Have you checked for codes? Have you reset the codes?
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
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.
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.
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)
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
because there is a crack in you engine and its runing over in to it
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.
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.
