Hi all, with the rewire from Advanced Auto Wire, I am looking to simplify the cooling fan system and eliminate the mechanical fan (Patton Machine) and setup a thermostatically controlled electric fan. The trouble is I need to decide which thermoswitch!
From the research I've done, it appears the general rule of thumb is that engines operate 5-10 degrees warmer than their thermostat rating (165). To prevent the fan from running all the time, getting the right on/off ratings is critical. With limited choices, I'm thinking I will try 185 ON 170 OFF, but am searching for some more advice on the matter before deciding.
Thanks!
