BD Diesel 1040023 Killer Frost Plug Plate for 2003-2018 Dodge Ram 5.9L/6.7L Cummins

The BD Diesel Killer Frost Plug Plate is engineered to seal coolant leaks from corroded or failed rear frost plugs on 2003-2018 Dodge Ram 5.9L and 6.7L Cummins engines. Coolant pressure inside the engine block can exceed 70 psi at high RPM before the thermostat fully opens, which often causes deteriorated frost plugs to leak. This innovative plate design eliminates the need to punch out the old frost plug, allowing installation whether the plug is in place, leaking, or completely blown out.

Key Features:

• Works with frost plug in place, blown out, or leaking—no need to remove the old plug
• Utilizes a large #333 O-ring for reliable sealing
• Five flanged head bolts secure the plate and contain coolant pressure
• Compatible with and without TCC (torque converter clutch) crossover tube
• Ideal for installation during transmission removal
• Can be installed with transmission in place if rear engine surface is properly prepared
• 6.7L engines require bellhousing support bracket removal

Installation: Estimated 6 hours. BD Diesel recommends installing this plate when the transmission is removed for optimal access, though installation with transmission in place is possible if the engine block surface finish is verified and acceptable.

Warranty: 12-month parts warranty

Emissions Compliance: This product does not require an Executive Order (EO) in California. By design, it is legal for sale and use in all 50 states as a replacement part.
