- About This Product
DescriptionThe coolant pressure inside the engine block can reach 70+psi at high rpm before the thermostat fully opens. This will cause a corroded frost plug to leak. This rear frost plug plate by BD Diesel is able to seal the leak without the need to hammer out the old frost plug.
For rear coolant frost plug on 2003-2018 Dodge Ram Cummins 5.9L and 6.7L 2500/3500. Note: 6.7L Applications require the bellhousing support bracket to be removed
It's recommended to install the rear frost plug plate when the transmission is removed. The plate can be installed with the transmission in place, however the surface finish on the back of the motor is critical and must be checked prior to installation.
