I have a 1995 ford escort 1.9 4 cyl. that the cooling fan will not turn off. I replaced the temperature sending unit that is supposed to control the fan, and I had the relay checked and it was OK.

    The fan goes off when the key is off, but when I go to start the car when the engine is cold, as soon as the key gets to the on position the fan comes on. It should not come on until the engine starts and reaches operating temperature.

Check the connection on the relay to ensure that they are making a good connection, there is sometimes a problem with corrosion at these connections, pull the relay and look at the connector end, is there any evidence of burning or melting? if so replace it. Hope this helps, let me know.

Cooling fan wont turn on

you are expecting the wrong temperature unit to control the fan. The temperature sender unit controls the temperature gauge and the temperature sensor unit controls the fan operation. It allows current to go to the ECM and when a pre set temperature is reached the ECM activates a relay and the fan starts . Two completely different units to do two different jobs so if it is doing what you say then there is a possibility that the wires are crossed or shorted.

How to install a coolant temp sensor in a 1995 ford escort

The coolant temperature switch and fan control switch are located sie by side, mounted in the steel portion of the heater hose that runs from the thermostat housing to the firewall, it is underneath the air intake tube and the ignition coil pack, mounted to the back of the cylinder head. Either drain out some coolant or be very quick, and you can unplug and unscrew each switch from the hose and replace it with a new one. Make sure the engine is cold. After replacing make sure to check the coolant level add as neccessary. The single wire connector switch is for the guage, and the other is for fan control. Hope this helps, let me know.

How to install a coolant temp sensor in a 1995 ford escort engine 1.9 liter

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Locate the coolant temperature sending unit on the engine.
  2. Disconnect the sending unit electrical harness.
  3. Drain the engine coolant below the level of the switch.
  4. Unfasten and remove the sending unit from the engine.
  5. If the same sender is to be replaced, remove and discard the O-ring. To install:
  6. If reusing the old sender, install a new O-ring.
  7. Coat the new sending unit with Teflontape or electrically conductive sealer.
  8. Install the sending unit and tighten to 18–22 ft. lbs. (25–29 Nm).
  9. Attach the sending unit's electrical connector.
  10. Fill the engine with coolant.
  11. Start the engine, allow it to reach operating temperature and check for leaks.
  12. Check for proper sending unit operation.

Replaced cooling fan ,cooling fan relay, and 40 amp fuse. Fan still won't come on. Any suggestions? 1995 Ford Escort w/ 1.9 liter engine.

Did you check the parts before replacement? Check if there is power supply to the fan when engine is hot and the fan should start. Also check the temperature sensor or the automatic fan switch located below the radiator, it may be faulty.
