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!

did a quick check..no rolled up wire under the batter tray...actually no wires under the battery tray other then the enclosded harness. I didn't lift the car up to try to find a sender.

If 1.8s did not have a temp sender then how did you know if you were overheating? There is no temp indicator in the gauge clusters...and the 75 1.8/2.0 owners manual only shows 1) oil temp gauge in the console or 2) oil temp gauge in the dash....this last one showing optional and is located where the parking brake "flasher" light is. Mine definitely doesn't have the latter. So the only temp indicator is the one in the console.

Guess I have to go jack up the car and crawl underneath.
