I have been seeing erratic readings on my M12 Universal Water Temp gauge. Min readable is 120 degrees, but sometimes I am seeing 150 when the engine is dead cold. Tapping the gauge does not get it back to min. Before I start replacing sender/gauge etc, I thought I would look for sloppy connections. Can anyone direct me to the location of the gauge sender on this engine? I want to check and clean, possible replace connector and see if this cleans up the issue.

Click on Universal, find your engine and then search in the "group" sections.
