BD DIESEL 1040022 CUMMINS KILLER FROST PLUG PLATE DODGE 1989–2002 5.9L CUMMINS

Product Description

The BD DIESEL 1040022 Cummins Killer Frost Plug Plate is the proven fix for a common coolant-loss problem on 1989–2002 Dodge 5.9L Cummins engines. From the factory, the rear freeze plug (also called a casting plug, expansion plug, or frost plug) can weep coolant over time—or in worst cases, blow out completely and dump coolant fast. This bolt-on plate is designed to stop the leak and keep the rear plug sealed with a heavy-duty O-ring and clamping force.
