I have a '97 Ranger 4X4 Supercab STX with 4.0 & 5spd. Recently, the temperature gauge has stopped working. I suspect it is the temperature sending unit. I guess i could go out and buy the CHilton's or Haynes... but then again, that's why you are all here

Can anyone tell me where I might find this little devil underhood?

Thanks & hello to all from a newbie to this board!

rangersvt It should be located smewere around your stat aera
posably on the housing

 

On my 95 4.0 it is close to the thermostat outlet on passenger side of engine, in intake manifold. Looks like a brass bolt with a single wire plugged into top of it. Mine sticks out at an angle.

I bought one at Oreillys for about 3 bucks- Borg Warner brand. Works fine.
I did have a hard time getting a socket to fit it. As I recall none of my deep wall metric fit. I think I had one 11/16 deep wall that worked, but another 11/16 deep wall was too small. I am not at home to check and confirm my memory.

 

You will see 2 similar sensors, one is the coolant temp sensor for the PCM, it will have a 2 wire connector on it, the second one is the temp gauge sensor, and it will have a single wire connector on it. Are you sure the engine is getting up to operating temp???

 

Thanks for the replies... I do see 2 sensors... the single wire one on the pssenger side is at least accesible! The other looks like it would require the complete removal of the intake! Regarding operating temperature... I drove it about 40 miles yesterday with temps in the low 40's here in Portland, OR. I thought that should have been warm enough to stir the coolant around a little!
