Where is the Temperature Sending Unit located on a 4600 Ford

dmay2005 · Sep 13, 2014

I have been having trouble with my Ford 4600 tractor with the temperature gauge running into the red. Put a new thermostat on and that did help. I'm thinking about replacing the temperature sending unit but cant locate it. Can anyone help or offer suggestions. The tractor goes into the red after just 15 minutes of running.

Front of the head. Just to the right if the thermostat housing.

If your tractor was built before 1979, suspect a stuck voltage stabilizer. Does the fuel gauge read high also?

Is it a false indication, or is the tractor really getting hot? Keep in mind that you may have a head gasket leak. Symptoms: Gets hot very quickly. Small bubbles in coolant when it gets hot.

You can get a test kit for combustion gases in the coolant at auto parts stores. Costs about $40.

No the gas does not read high.

I'd still suspect a voltage stabilizer if you have a pre-1979 rig. Remove the dash with the wires still attached and turn the key on. Probe both terminals of the stabilizer (looks like a circuit breaker or flasher relay) with a test light. One should be hot all the time, the other should pulse on and off. If they are both on solid all the time (wait at least 30 seconds or so), stabilizer is faulty and this is why your temp gauge reads high.
