    Temperature gauge calibration

    There seems to be a 10 degree difference between my US Marine original temp gauge and the temp from my IR gauge when read at the block. What could be the root cause, the gauge or the sender?

    My Maxum is the same. Best I came up with is weak grounding as the temp sensor is in the t-stat housing and the ground relies on brass eyelets in the gasket to provide ground but these go away over time due most likely due to dismilar metals.

      I would clean the connections, back of gauge also.

      Gauges are notorious for not being 100% accurate.

        I agree. Mine are the same, read many posts about these gauges being off to some degree. Your IR temp gun is more accurate. Also your engine temp will read the hottest at/near the t stat housing.
