Part Number:  PDM-08200

• Designed for clean, tool-free installation
• Built for off-road and performance Cummins setups
• Durable solution for common coolant leak points

Notes

Clean the freeze plug bore thoroughly using a wire brush or emery cloth to remove all rust and scale. Add a small chamfer to the bore edge to allow the O-ring to compress properly. Lube both the O-ring and the bore with motor oil.

Install the plate by hand only; no hammer or tools needed. If it doesn’t go in smoothly with hand pressure, double-check your prep. Damaging the O-ring can lead to a poor seal.
