Hi, my temp gauge stoped working from what I understand is that the temp sending unit is bad, I know it is located on the left side cylinder head somewhere between #1&3 cylinders but I cannot find it and Im not sure exactly what it looks like. Any help and or pictures would be greatly appreciated.

 

Could be a few things...Check your actual gauge in the car first, could be bad..Check the wire connected to the sending unit is not loose...I had that problem once, my gauge would not read..reconnected the wire and bam she worked again....Was a loose connection

 

#1 and #3 cylinder are on drivers side of vehicle, thier is only one sensor/sending unit there..should be pretty easy to see...

 

usually looks like this

Thanks, Ill check it out tommorow, and i did have my dash apart to do my speedo cable but the temp gauge still worked after that.

 

ok I found the sending unit and the wire is not connected at all and the metal tab with the hole in it sticking out isnt there , looking at the wiring diagrams it says its a dark green wire but once again i cant seem to find that wire

 

check along the frame rail, under the steering shaft, and along the firewall...look for a loose wire. It is all alone for like 10-12" before it enters a wire loom

 

Thanks, ill be sure to look for it

 

There were two different styles of sending units used during the generation, and the change wasn't a consistent-year change, like the data says, so you could have either style.

If yours doesn't look like the one in the link IROCmonkey posted, then it probably looks like this one:

The sender in my '87 is original, and it's like the later style in the link I posted.

 

That is exactly what mine looks like and i found the clip, it was strange at first because i was expecting a spade type connector, havent had a chance to see if it works yet, the car is still on a lift at school just finished with other misc. wiring diff oil change ,wheel bearings, brakes and many other things
