Question about Temp Gage - where should it rest normally? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everyone!

Question - For all you owners with functional gages - where should the temp gage rest when the truck is at operating temp?

Here's the story:

Pulled the cluster out tonight to rebuild. When I got the truck the the stock temp gage was pegged and the P.O. had installed an aftermarket one.

I knew the problem was likely a grounded wire somewhere and sure enough the little metal tabs on the back were really loose.

Got it all re-assembled and back in tonight and it's nice to have full lights and functional signals again!

Now, the gage seems to be working (at least it rests at C instead of off the chart) - but I'm wondering if it's working correctly. There is a 195deg thermostat, and the aftermarket gage rests right at 195. So that appears to be right. However, the dash gage comes to rest at about the 1/4 mark past C. I was assuming the right resting place would be about 1/2 way.

If 195 should be 1/2 way, how would I go about fixing it?

Thanks!

mine rests right above the 1/4 mark at operating temp assuming it's not extremely cold or hot outside.

i agree, both of my trucks rest at or just aboe the first tick.. or 1/4 mark...

Good news then! Sounds like it's working. I assume you guys are also running stock thermostats?

Thanks!

Yeap! 1/4 mark with 195 thermo

Mine is right by the middle at operating temperature. with a 195 thermostat.

I had a 160 in it before and it was right about where you guys are saying.

If you've got a newer sending unit with an older gauge, it will just barely come off the C, but if you've got a newer gauge with an older sending unit, it'll sit at about half way.

Judging by this car - it's the original sending unit and I'm pretty sure the original gauge.
