High Cylinder Head Temperature
I have a 1980 C-180K with an O-470/U engine. It has a GEM 6-cylinder EGT/CHT gauge in addition to the stock engine instruments. The stock, single cylinder, CHT gauge continuously reads higher than the 6-cylinder GEM, sometimes threatening to pass the red line on the gauge. The GEM reads good temperatures at the same time. I'm certain that the stock gauge is reading too high, but I can't allow a red line even though I suspect the gauge. I've considered disconnecting it, but that doesn't seem right. Any suggestions?
