Where is the temp gauge sending unit on an '87 F150 4.9L I6?
Where is the temp gauge sending unit on an '87 F150 4.9L I6?
My truck is an '87 F150 4.9L Straight 6
I know there is a sending unit (2 wires) on the thermostat housing, but is it the one for the gauge or for the computer?
My temp gauge is not working at all and I ohmed the sending unit in the thermostat housing and got 47K ohms cold and 3.2K ohms @ normal operating temp- is this a normal range.
I've already swapped out the ammeter/temp gauge set because the old ammeter gauge wasn't working either, but is now. The temp gauge still doesn't work, but I don't know if I'm checking the proper sending unit (the one on the thermostat housing).
