Electric Gauge vs. Scanmaster Temp

[mtbraun]

My Autometer ES coolant temp gauge consistently reads about 8 degrees warmer than my Scanmaster temperature. I plumbed in the Autometer gauge where an old sensor was on the drivers side front of the intake manifold. I forget what that temperature sensor was but used that based on advice from a previous post.

I'm hoping my Autometer gauge is more accurate than the SM reading. Anyone else see this?

I think you tap into pass side.

My Autometer ES coolant temp gauge consistently reads about 8 degrees warmer than my Scanmaster temperature. . . . .

Does it read the same when cold?
Verify the electical ground to the gage with an ohm meter.
