BD Diesel Killer Frost Plug Plate – Part # 1040023

The BD Diesel Killer Frost Plug Plate is designed for heavy-duty diesel applications, specifically fitting 2003-2018 Dodge Cummins 5.9L and 6.7L engines. This component is essential for sealing leaks caused by high coolant pressure, which can reach over 70 psi at high RPMs and lead to corrosion and frost plug failure. The plate allows for a secure seal without the need to remove the old frost plug, simplifying installation during transmission service or engine repairs. It is compatible with frost plugs in various states—intact, blown out, or leaking—making it a versatile solution for fleet and heavy-duty diesel engines.

Installation is recommended when the transmission is removed, especially on models with the 6.7L engine, where the bellhousing support bracket must be temporarily removed. The plate can be installed with the transmission in place if the surface finish on the back of the engine is properly inspected and prepared. The included components feature a large #333 O-ring for a reliable seal, along with five flanged head bolts to contain the coolant effectively. The design accommodates engines with or without a TCC crossover tube, offering flexibility during installation. The BD Diesel frost plug plate eliminates the need for hammering out the old plug, reducing labor time and risk of damage.

Constructed with durable materials to withstand the thermal and mechanical stresses of heavy-duty operation, this frost plug plate ensures long-term reliability. It is an ideal choice for fleet operators and diesel enthusiasts seeking a dependable repair solution that minimizes downtime and maintenance costs. Proper installation and sealing are critical to preventing coolant leaks and maintaining engine integrity under demanding conditions.

• Heavy-duty durability designed for high coolant pressures exceeding 70 psi at high RPMs
