My cooling fan on my 96 T-Bird with a 4.6 is not working. I have replaced the thermostat and the temp sensor with no luck. I find that when I disconnect the cable connected to the temp sensor, the fan will work so it is not the fan itself. My temp gauge is running above normal and I have had a slight loss in coolant but no visible leaks. Any ideas?

This happens when the head gasket blows or the engine coolant temperature sensor is not working right. Here are two guides to help us see whats going on also the location of the temperature sensor.

Check out the diagrams (Below). Please run some tests and get back to us.

Thank you galletta61 for your reply. I had checked the engine fan fuse in the high current fuse box and it is good. Then I did the head gasket test and it tested positive so its off to the shop for a $900.00 repair :( thanks for your help though.

Hi, I've got a 1995 Ford Thunderbird LX with the 4.6 engine, 87,000 miles. The cooling fan does not come on at all, not even with the A/C on. It does come on at high speed when it's supposed to, but the car runs hotter than it should when driving in town. Could this be a bad fan relay, and if so, is it part of a module? I've heard ICRM and CCRM, but I don't know where it is located or if the relay can be replace by itself or as part of a module. Please help! Thanks

What I meant to say is that the fan does not come on at LOW speed when it's supposed to. The high speed does come on at 220 degrees.

1997 Ford Thunderbird cooling fan stopped working. Couldn't find a relay. Put a toggle switch to manually turn it on when running. Does it have a relay or what can I do to fix it? I would greatly appreciate your help.

Engine Cooling problem
1994 Ford Thunderbird V8 Automatic 130000 miles

i have been working on my 94 ford thunderbird Lx and as of a few weeks ago I took it to the machanics and he said it was in good condition with the exception of the steering rack, how ever when I turned the car on yesterday the fan did not turn on. What are some possible reasons for the radiator fan not to work?

Fans do not operate at all times, if you mean they didn't come on during after reaching proper temp. Then the problem could be many things. First check fuses and cooling fan relay(s). If OK test engine coolant temp. Sensor. If OK as well then need to test the fan motors.

Did you check for voltage and ground at the fan wiring connector when the fan should be running? Maybe the fan motor is faulty? Did you try to peck a little on the side of fan motor, when it should be running? Don't get caught in the fan. If it takes off, check the wiring connector, if ok, suspect the fan motor is faulty.

Can you check applicable trouble codes? Some of the national brand auto stores will check codes for free. If you want to check codes yourself, at the least, you need an obd2 code reader.
