my water gauge stopped working

[walshja]

the oil pressure still works, but my temperature gauge reads cold and never moves.

looked in the manual and it tells me how to remove the gauge, but not how to troubleshoot.

any tips on where to start?

Most likely, it sprung a leak. You have three options
1) Buy a replacement unit.
b. have yours repaired professionally
III: attempt a homebrew patch job that someone will supply a link to soon.

I did that one too and it worked for me.

Trevor, any recommendations?

There is a unit on eBay I just bid on (and got outbid already)

Would you shy away from used ones?

The one from Moss will work, but it's not the same dial, and it's $175

Look here if you want a replacement unit rather than repair:

This is how I fixed mine. It is still working.

I went the ebay route for my replacement. As long as you get it cheap, you have nothing to lose. Just be sure to ask the seller to stick the bulb in boiling water and tell you how far it moves, before you bid! If it moves on beyond 'N' at 212 degrees, it's close enuf to tell you what you need to know.
