How does the 2500 Cummins electric fan work?
Does the fan kick on when it starts to overheat, reaches operating temperature? My brothers fan clutch harness got caught on the blade, and ripped it off. I temporarily patched it up, and connected it directly to the connector on the truck. How can I verify that the fan is working? Thank you.
