I'm using a gauge cluster out of an early 80's GM, Caprice I believe. New sending units the oil pressure works fine the voltmeter works fine the Water temp runs about 50 deg. high, the fan cycling switch comes on about 185-190 and the temp gauge reads 260, were there any other temp sensors? I thought they were all pretty much the same. It tracks nice and smooth just goes higher than it should. Any help would be appreciated. Thanks

I found a chart that shows the resistance value for a given temp. I will try to post the link

Try this place ,it should help

linkie no workie
Just google : GM gauge sending unit values
It is about 5th or 6th down the first page look for the pdf one.

Thanks for the help, I now have a good place to start
