stupid question....temp gauge and sender, temp doesn't register...where is sender? Options

[jim912928]

Ok, my temperature gauge doesn't register at all. Car runs fine, but I really don't want to run it long without knowing what temperature range I'm running in. So, I need to begin diagnosing this problem but first I'd like to know where in the heck the temp sender is located? I'm guessing it can only be 1) wiring, 2) gauge or 3) sender. So, once I find out where the sender is how do I test it?

Car is a 75 1.8l....again, as usual...thanks in advance!

That wire comes out of that main harness under the battery tray and passes through a grommet on the engine shelf (if it is there). You should'nt have to jack the car up. From the drivers side just in front of the wheel.... look 1/2 inch back from the engine crossbar. Basically look across the bar until you see the first sign of the engine. The "taco plate" is right there. If it has a temp sender in it.. you wont see it. The sender has a cover on it. Look for a single wire leading to the taco plate.

Only the 73 and 74 2.0's had a gauge for reading oil temp....opinions may differ... but this what I see day in and day out..
