temp sender on 85 12a
I need a little help with the location of the temp sender. I know its located on the block somewhere near the oil filler, but I don't see it.

And for the hijackers. The one on the rad is for the emissions control computer.

BTW, I just added this thread to the FAQ. Now everyone will know all about the all-important temperature sensors.

Yes, that looks like the part BUT..... Quoted from this Mazdatrix page: Sensors, Senders, and Miscellaneous Electrical
"Note: A few years ago MAZDA changed the thread on the water temp sender in the rear side housing from the straight thread that they had used forever, to a metric pipe thread. All NEW rear housings have the new thread. It is essentially impossible to tell which you have with out looking at it. Most cars still use the straight thread. However, if the engine has been replaced with a FACTORY rebuilt, there is a small chance you have the pipe thread. The new sender will not read correctly in pre-80 cars"

I could have the wrong one, since there were but could it be missing from the car? The hole that is there is a little smaller than the part I have, so I'm not sure about the threads in the housing.

Well, the temp sender is broke off in the block, I tested the loose yellow wire with a test light and the gauge went up some, so it works. Anyway, anyone have any suggestions for technique, tools, etc. to get this thing out?

Mine broke, too. It's a pain in the *** to get it out, but like Carl said, an easy out will do it, but you're not gonna have a lot of room to work with.

Ok. Now here's an important question. I don't have a temp sensor in the block right now. Could I wire the temp gauge to the sensor in the back of the water pump housing? i.e. do they have the same resistance for the same temperature?

My recommendation is to put the correct plug into the water housing and run a new adapter for your temp sender where the stock one is located.
I'm not sure what the thread size is, but check this link just in case.

Upon doing some searching, might not have to worry about the location of the sender. Try this link, see if there are some answers in there that should help you.
