Temp gauge fuctuating 500ho carbureted
I have a late 90's 500 hp I did a water impeller on , cleared all hoses and oil cooler and have great flow out of exhaust. Problem is the temp gauge keeps going from 130 to 180. Replaced thermostat and insured that grounding gasket was at base, replaced temp sensor and used my heat gun an the hottest temp reading I could get was 150 at the oil pan everything else is below 100. Grounded temp gauge and it peg's.Replaced 1" dump hose on port header because it was collapsed inside. About the only thin that hasnt been replaced is the water circulating pump , any ideas?
