AFA Industries A3928640 aftermarket engine coolant thermostat for compatible Cummins C-Series 8.3L diesel engines, including applicable 6C, 6CT and 6CTA configurations.

This 160°F engine thermostat regulates coolant flow through the engine cooling system. As coolant reaches the thermostat’s opening temperature, the thermostat begins opening to allow coolant circulation through the radiator, helping regulate engine operating temperature.

The AFA A3928640 is designed as an aftermarket replacement for Cummins OEM part number 3928640. It is suitable for compatible cooling system repairs, thermostat replacement and diesel engine rebuilding applications.
