The 180 Mr Gasket thermostat worked as it should on our trip to S.C. Stayed right on 180 till we hit Saluda mt. Stayed on 55 mph going up and temp did rise to ~190 but not hot enough to engage fan clutch. I had found the new fan clutch I was running was a non thermal unit? It looks the same as the thermal unit I replaced it with, small spring and all. So what's the deal with a non thermal fan clutch? I never heard the non thermal kick on with the old thermostat even with temps running in the 200 range. Didn't even hear it on initial start up. Now that I have a proper working thermostat I can hear the new Delco clutch on initial start up and it quietness down as it should.
