I have a 99 F150 4.2 liter. temp gage show redline but engine is not over heated. let it run in my garage for 20 min in the red and then I shut her off and turned her back on; gauge went to normal position. fuses look good. I cant seem to locate my temp sending unit though. there is a plug to the right of my thermostat housing but can locate where the unit is!!!!
I looked in a service manual and only saw a temperature sending unit on the 4.6L...it is located on the front of intake on the right hand side.
The 4.2L has a head temperature sensor on the rear of the left hand head. I am sure someone else will be of more help.
