temp gauge

[72oh]

Hey guys! This is my first post. First of all, I just bought an 86 720 4x4. Thing runs like a top but obviously will need some tlc. My question is has anyone had experience with a bad temp gauge? Mine stays below cold. I will check to see if it is disconnected at the sensor today as this will be the first chance I get at checking it. Just thought I would post this now to give time for responses. I will have other questions later as there are a number of small things I would like to repair.

thanks,

Keith

This might be another one of those Quirks.

I have an '86 720 and the temp gauge hardly gets above the cold line at the bottom.

My gauge usually hangs out about here, and I know it works cause once I lost my fan belt and bang-zoom, way hot.

Mine gets to just below half when fully warmed. Unless I'm going 110 km/h (60mph) in a -40 day then it dips to 1/8 lol.

dangit!! Hey, does anyone know where the temperature sender is? I think I can figure this out if I know how it is wired. And ofcourse, my gas gauge is not working either!

im pretty sure its this little guy just under the top radiator hose in the intake manifold..let me know if im wronge!!lol mine doesnt really do much eather if anything l dont really know...let us know if you get it figured out!

I have a theory that these trucks, under normal operation, especially the napz, run fairly cool. I installed an aftermarket manual temp gauge, I can only get the temp to go up when in 4wd for a long time when my clutch fan on the water pump worked. I know the gauge is accurate, since it manual, meaning no electric sending unit.

Mine works great. It's usually about 1/4 but goes through the whole range as I had a leaking radiator.

Started it up the other day and both the temp gauge and the fuel gauge began working. Been working ever since!

I think the problem may be with grounding...

[flinterman2000]

On all vehicles grounding is a real problem. We need to check this aspect of the vehicles more often.

they ain't workin' again! AAARRGGHHH!!!

sounds like you have a few gauge issues overall man... but everything that has been said about these trucks running cool is true

with all the stuff i have removed from the bay, and the extra cooling i have added.... i will NEVER get close to half way on my temp gauge unless i lose the belt

Thanks, man!

By the way, when the gauge decides to work, it runs just where I think it ought to-- right inbetween cold and middle (a quarter of the way up). So I am not worried about the temp, just would like to be able to monitor it!
