  • 180 degrees ok?

    I've always noticed that my 6 cylinder McKinnon runs on the hot side of the guage, but didn't know if that was really hot or not. Today I measured it with a candy thermometer and it's running at 180 degrees. I have NOT looked at the thermostat to see what that is, but the car runs well and never gets over that level (unless I'm sitting idling for a LONG time in very hot weather). Am I okay or should I put in a cooler thermostat (assuming the one in there is a hotter one)?

      it probably LOOKS hot because the stock thermostat, at least for the Stude-engined cars, was 170 degrees (and I would bet that you have a 180 unit in there now, as that's all that's sold in parts stores.) I have the same effect in my '55 coupe, '63 engine with new 180 degree thermostat - in that car stock thermo was 160 degrees so "normal" temp is almost to the top of the white bar of the gauge. Car seems perfectly happy however and I've always heard that engines should run a little warm to keep the oil clean. Don't want to put 160 degree thermo in unless I have to to keep it cool. Put maybe 20-30 miles on the car yesterday, some of it cruising at 50-60 MPH and it didn't go past 180 degrees so I don't think it will be necessary; if anything the radiator would be my first fix (it looks a little sketchy)

      But anyway you don't necessarily have a problem at all.

          I suspect a 180 degree thermostat will be fully open around 184 to 186 degrees.

            That's seems to confirm my suspicions. I'll pull the thermostat and see what size it really is. But, the car seems to run fine, so I'm not going to worry about it much.
