95 Escort radiator fan switch????

[Retired-1]

Aloha! This is a 95 Escort wagon LX 1.9L and the radiator fan is not coming on and the car is overheating. (When the engine is cool the ac would turn on the fan, but when it got hot, it would not.) I was told here to jumper the fan and it does work with direct voltage. Big Mahalo to "hummbug"! You saved me over $150 so far!!!! So I took out the relay and called the local auto parts store. They say it could be either the switch or the relay. Where is the switch and when I do find it, how do I get it out or off??? Any tricks to it? I have a Chilton manuel on this car but it does not say. Is there a way to test the switch and the relay? (The fuse appears to be ok.)

I believe your radiator fan is controlled by the engine coolant temp sensor. The sensor sends a signal to the PCM, which turns on the relay to the fan. The engine coolant temp sensor should screw into a water jacket on the engine, probably in the cylinder head. Good luck with it.

FYI: Engine coolant temp sensor: Located under/near coil pack, along the heater hose inlet which is attached to the thermostat housing on the right side of engine. There is a metal unit there between two hoses. The sensor is attached on this metal "bridge". There is a small sending unit next to it that goes to the dash indicator.
(If you have the CHILTON manual, see page 3-27 for pic.)

I was told by Napa employee to unplug the unit and jumper the connection with a wire. If the fan came on the sensor was faulty. The fan did come on. Tried to remove sensor via bolt and was unable to budge it. Oiled it and got strong neighbor and he failed also. Needed deep end socket. Took it to local Goodyear garage and asked them to try and remove it. I informed the mechanic that it should probably be removed by taking the hoses off on each end. That meant removing the ignition coil pack first as you canNOT get to the release clamps on the hose. He said he wanted to try first and he put too much torche on it and broke the seal of the metal housing clip attached via a weld. (Don't ask a Samoan for help when you don't want too much strength!)

The problem with this location is there is nothing to really get a good grip on for leverage, and the fact that it is held in place by hoses on each end. It bent and then broke seal, which caused fluid leak. Now the garage has the car.

I'll keep ya'll posted.

I know the hose clamps you are talking about. They are not designed to be removed. I hacksawed mine when I replaced the hoses then put regular hose clamps back on. While you have this off it might be a good time to put new hoses on.
