Cummins will notify the affected Navistar customers and dealers will disable the fuel heater by either installing a plug in place of the heater or otherwise rendering the fuel heater non-operable and remove the fuse supplying electrical power to the fuel heater and install a cover over the wire harness connector, free of charge.
