Rewiring or hooking back up guages

[sky56]

Hey everyone ive got 2 guages in my 75 K5 that dont work. Temp and the clock. Im just curious if anyone can provide pics and or the know how on what il need and what to do and all that. Ive done it on other vehicles but just want to make sure this isnt different. The clock is not a priority but it would be nice if it worked. Thanks for the help. take care everyone

Clock is probably toast. But here is a good site on the temp gauge.

Checked out the website very helpful. But let me ask if it's not hooked up at all it's just wired from the guage to the plug that goes into the block right? If I'm wrong please let me know. The clock probably is toast but it wouldve been cool to work. Thanks

Not sure I'm on the same page with you. Are you trying to make it work without being in the instrument cluster?

No I want it to work in the cluster. I just don't know if it's hooked up and where to look under the hood for the coolant temp or just temp sensor in general. I'm sure it's a simple fix but just want to do it right the first time

The temp sending unit is right next to the thermostat housing. one thing to check is the nuts on the back of the gauge. They should be tight. If it is hooked up, the link I posted above will be your next step.
Does it work at all? Partial range? Full range when cold?
