If the plug appears melted, likely you will need to at least partially destroy it to get it off. Sometimes a little wd40 will help. Make sure you draw a picture of where the wires go so if you do damage it you can still attach the wires without the plug. If you need to do that use heat shrink tubing or tape around each connector to prevent any possibility of a short to ground.

All newer models have electric fans,you have sensors and relays that tell the fan to turn on and off,you can test if your fan is dead or your sensor or relay.from your fan follow wire until you find a connection plug,usually about 20 inches from fan. disconnect plug and run two jumper wires to your battery. this will tell you if fan is problem. continue following wires to find sensor, use test light when engine is running and getting hot to see if power is making it to sensor.if it is your sensor is not sending power to fan. if no power is making it to sensor, check fuse box on firewall of engine compartment for fen relay some models have 2. Or you can hook the fan up to constant power when car is running via the fuse box under dash, or hook fan up to a toggle switch mounted to your dash, either way you need to run new wires from your fan

Radiator fan not working


temperature sensor bad, replace that doesn't work, fan motor may be bad, if you disconnect the electrical connector of the fan, and jump wires from the positive and negative of the plug to the batterys +/_ to see if the motor runs, or not. then you'll know which is bad, motor or sensor.

How do I change the engine radiator fan motors on my 2001 Buick Century?


  • Remove the passenger side kick panel using a Phillips head screwdriver. Pull the rug back from under the blower motor to allow enough room to drop the blower motor without the rug interfering.

  • 2

    Disconnect the electrical plug from the blower motor. Pull the rubber vent hose out of the blower motor.

  • 3

    Remove all the Phillips head screws securing the blower motor to the housing. Drop the blower motor straight down.

  • 4

    Install the new motor in reverse order of removal

Cooling fan burned up


Get a new fan motor and blade from GM or from an aftermarket supplier.

GM parts are usually better than the aftermarket ones, though for fit and functioin.

May also look into checking the relays and harness. If the terminals of the fan show they are getting current, then the motor will have to be replaced if not turning or obviously burnt.

Good luck on this repair.

Inspect/Replace

CAUTION
The fan that draws cool air across the radiator can be driven by either a belt or electricity. Rotating fans can be dangerous. Some are controlled by an automatic switch and can start unexpectedly. When working on electric fans, keep in mind that electric cooling fans should be disconnected when working around them.
When replacing a radiator fan motor, always refer to the vehicle's service manual. The following is a general guide for cooling fan replacement.

  • Disconnect the negative battery terminal at the battery. This is necessary on vehicles using electric fans, but some vehicles may require the relocation of the charging system components.
  • Drain the cooling system.
  • Loosen or remove the hose clamps, then remove the upper and lower hoses from the radiator.
  • Disconnect the transmission cooling lines and plug them off, if equipped.
  • Disconnect the electric fan motor connector, if equipped.
  • Remove the fasteners attaching the fan module to the radiator.
  • On some vehicles equipped with air conditioning systems, it may be necessary to discharge the system. This is the case if the radiator and condenser can not be separated in the vehicle.
  • Remove the upper radiator cross member or mounts.
  • Disconnect and plug the air conditioning lines at the condenser, if needed.
  • Remove the radiator and fan module as one unit if possible.
  • Separate the fan module from the radiator.
  • If required, separate the radiator from the condenser.
  • Remove the old fan module.
  • Install the new fan module onto the radiator.
  • Reattach the fasteners attaching the fan module to the radiator.
  • If equipped, connect the electric fan motor connector.
  • Reinstall the radiator.
  • Refill the cooling system.
