Product Description
The BD DIESEL 1040023 Cummins Killer Frost Plug Plate is a proven solution to one of the most common and costly Cummins issues: the rear freeze plug (frost plug / expansion plug) leaking or blowing out under pressure. This bolt-on reinforcement plate is designed for 2003–2018 Dodge Ram 5.9L and 6.7L Cummins engines and helps prevent sudden coolant loss that can lead to overheating, downtime, or engine damage.
Unlike traditional repair methods, this kit does not require removal of the original freeze plug. It works whether the plug is still installed, already leaking, or has blown out completely. A heavy-duty O-ring seal and five flanged-head bolts keep coolant contained and lock the plate securely in place for long-term reliability.
