Cooling fans do not turn on and car overheats on a 2001 Chevrolet Malibu. What is the problem? I have checked the fuses and they seem OK. Could the problem be the thermostade?

Relay Driven Dual Cooling Fan Diagnostics cooling sensor ,which one ? car overheats how are you determining this ? temp gauge ?

Try removing the cooling fan relays one at a time in the underhood fuse block , If they go off and stay off after you put the relay back replace it

turn ac off then the fan will go off make sure ac button if you have one isnt pushed inwait a minute fan should turn off does temp gauge inside car raise in temp after running a while

SOUND LIKE COOLING FANS NOT RUNNING CHECK AND SEE DOES COOLING FANS TURN ON WHEN ENGINE OVERHEATS IF NOT CHECK COOLING FANS FUSE AND RELAY IF BOTH CHECKS OUT GOOD HOT WIRE COOLING FAN.IF IT WORKS.PROBLEM COULD BE COOLANT TEMPERATURE SENSOR- PCM- AND OPEN OR SHORT IN WIRES.IF COOLING FAN DONT WORK WHEN YOU HOT WIRE IT PROBLEMS THE FAN MOTOR.

new radiator fan relay also? If not replace that relay too

There are also relays usually in the engine compartment that control them, check that

Check the cooling fan, its sensor, the relay, the fuse. On most cars the fan is not needed on the highway, but engine overheats it it doesn't switch on inside the city. Also, clean the system with a special liquid according to the directions on the can and use coolant after that, water causes corrosion. While pouring/filling/cleaning, keep the heat switch on max heating to allw circulation via the heating radiator.

replace coolant sensor connector?if so can u get a thermo lazer gun to check the block temp? this will tell u if the gauge is incorect,,,go ahead a bleed all the air out of cooling system and see if that does the trick

okay pull the temp sensor connector ( disconnect it) and turn car on if the fans run then its the temp sensor.... part # wt3000.
Theres also 3 relays that turn the fans on in the fuse box cooling mode fan relay @15 which is part number 7234. and cooling one # 1 which is 3604, and cooling fan #2 which is 7236.
I have the same car...give me a fan clutch cooling system anyway of the week. simple and efective no problems.

i had that trouble it was the temperature sensor that was defective thanks pierre
