1999 Ford Ranger XL Shows Hot
Hello Everyone;
Thank you for allowing me to post my issue.
I hope I am posting in the proper area, if not, please excuse my ignorance and place it in the proper forum.
I have a 1999 Ford Ranger, 4x2, 189,000 miles, 6.0 4.0L engine.
I had to replace the odometer from a salvage yard not long ago, but my issue is the "Cold/Hot" Temp Gauge shows almost on "H". I changed out the Coolant today along with the Thermostat. I thought I had the issue resolved because it gauge initially started about halfway between C and H, but I guessed wrong. It eventually went all the way to H.
Can anyone provide me with some recommendations of where to go next.
Thank you again for the opportunity to post.

On the lower intake just above the thermostat housing you will see two temp sensors screwed into the intake.
One will have 2 wires, that is the ECT sensor only used by the computer.
The other will have 1 wire, this is a temp sender only used by the dash board gauge.
The 1 wire sender is the one you want to test.
Engine cold, key on
temp gauge should be at C(cold)
remove the 1 wire from the sender, unplug connector
gauge should drop to below C
Get a piece of wire and push it into the connector make contact with the 1 wire
Ground the other end of that added wire, to engine or battery negative
Gauge should move all the way up to HOT
If above happens exactly this way then wire and gauge are fine, replace temp sender, make sure parts guy doesn't give you the 2 wire sensor, you want the 1 wire SENDER.
If gauge shows above C when engine is stone cold then yes, your wiring in the dash is the problem
