84 Spider Dumb question of the day

[RickU]

Per the suggestions on this board I want to ground my Water temp sensor as a first step in troubleshooting my guage that is always at "12 '0clock" . Can someone tell me or show me a pic of which sensor this is. I see a number of them and can not figure out which is the water temp sensor. Thanks much !!!!

It is mounted up by the thermostat, horizontally, like a little spark pluggy.
See page 07-02) "Engine Cooling Systems" of the workshop manual.
Go to IAP website and look up the part for a picture.

Here's a snip from the shop manual. #39 is the fuel injector (3rd cylinder I think). #41 is the one you're searching for, #38 & #40 are temp sensors for the ECU's (computers).
