Hello all,

My temperature gauge is dead. I got the car like 8 months ago and it hasn't worked from the start. She runs fine, no problems and the heat works good too, just the temp gauge is dead.

Do I just need a new coolant temperature sensor?

Any thoughts.

Jason

yes, but you need to replace the coolant "sender" on the right side of engine. There is also a coolant temp sensor, so do not confuse the two.
 






The single wire one is for the gauge. The 2 wire temp sensor is for the computer.

Yes, the one that looks like this

Thanks, I'm still new to mechanics, so I don't understand, I'm gonna check my Haynes Repair Manual to see if I can figure it out and do some homework.
 












Ordered, 16 bucks with shipping, not bad.
 


















ok on My 93 the temp sender looks like the one pictured abaove, with a small threaded type stud for a wire connector to slide onto

Here is one from a later model. Although the connector is different, yours is still in the same location

Thanks Turdle for the picture, big help. Using my original picture, I put a new arrow of where I think your pointing too. I think this location is it, or somewhere around this area. I'll get a better picture tonight.

Here is a bare manifold. I have too much junk

Red arrow is ECT sensor. It helps the pcm calculate fuel ratio. This is not the problem sensor.



Green is Coolant sender, which is the gauge sender. This is the one you want

Here is my engine. I have a different looking cable to the sender, as I am using an aftermarket gauge. These will show you where your sender is though.

Nice :D
 






Thanks for this thread guys... it's helped me out a lot in understanding where the temp sensor is at.
 






I changed the temperature sender a few weeks ago, I needed a deep socket 18mm (i think) to get it. Quite a bit of coolant came out, but temperature gauge still not working, battery level gauge also dead. Maybe I need a whole new gauge cluster?? or perhaps try to replace the other component, the temperature "sensor"?
 






I might be in the same boat here soon... i am about to replace my "sender" to see if it fixes it... hopefully i'll have good news :O

Before you throw money at the sending unit, you should make sure the gauge and the wireing for it are working.

Its an easy test. Just take the single wire that goes to the sending unit and ground it. If the gauge and wiring is good it will peg the gauge. If it doesn't move you have other issues to fix before you change the sending unit.
