99 ford escort running hot . i replaced the thermostat. flushed the radiator . had the synsors checked . no leaks no noice. is it my radiator?


You may need your radiator rodded and cored. But, before you do that check the relay that controls when your electric fan engages to pull air through your radiator. The sensors that control the electric fan are usually in the side tanks on the radiator. This sensor heats up and tells the fan when it needs to make the electrical connection to engage the fan to cool the radiator coolant. I would probably bet that is what is malfunctioning. They are a relatively inexpensive part. Good luck.

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.

Electric fans do not work do you have any ideas my car runs very hot fans never seem to come on


Electric radiator fans? Just a guess but it could be the water thermostat. They are very inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. This is the function of the thermostat which is inline to the water pump and allows the engine to warm up before cooling through the radiator then when the fan thermostat on the radiator heats up the electric fans will run. You might be able to squeeze the upper radiator hose to feel if pressure is building up or water is flowing.
