:confused: Changed my 70 SS from lights to gauges. Temp gauge reads 20 to 25 degrees less than engine temp. Thanks for any info...

How are you determining true engine temp?

Yes we checked the true temp on engine, we have a electronic laser temp gauge. And we put in the temp sender that came with gauges. Car normally runs at 180 degrees and the new gauge sez about 150 to155 degrees. :confused:

Heres a post on how to check the calibration of temp gauge......
