Bill,
I’m also having an issue with the fan clutch on this unit. The original one didn’t work at all, so it’s now replaced with a new one from IH. This new one never shuts off. It has a temp adjustment that changes the preload of the bi-metal spring, which I have messed with and it still runs 100% of the time. My coolant temps stay ~170-180.
Have you messed with the fan clutches in these at all? It’s mechanical.
Jeff
