My Cummins dealer shop foreman mentioned that running the fans in high speed constantly would damage the systems parts from long term high heat in the system.
Another reason to update the fan speed controller from the 180 to a 199 unit.
The 180 runs at low speed until 165 then starts going faster.
The other one runs at low speed to 184 then ramps up to full speed at 199.
The thermostats in our coaches do not open fully until 195.
Foretravels use of the lower setting full speed excessively heats the systems oil which can contribute to system issues in his opinion.
