Water Temp Gage on 73 GT Inop - where to start?

[paul.catherine]

Hi all,
In my recently acquired 73 GT, I see I have a dead water temp gage... First glance shows no illness at the thermostat end, but I could be wrong? Is there another place to look about before opening up the dash for broken wires etc? (IE, is there a common breakage place for this gage?)... Thanks for any help!

Well I need to open up the dash anyway, I have the classic dead clock problem too

Any thoughts or guidance is appreciated... I looked over in cooling systems, and I looked at wire diagrams and am still abit in need of a 'push in the right direction'.... thanks!

I had the same problem on my 73 GT years ago and traced the problem down to a bad gage! I just went on-line and found another one and replaced it and haven't had a problem since. This sounds like it may be your problem...

Before you pull your gauge panel, consider that it could also be caused by faulty wiring at the temperature sender unit (on the thermostat housing) or a bad sending unit itself.

thanks all around - indeed, it DID turn out to be a bad connector on the wire, clipped to the temp sending unit! works now like a champ! Thanks!
