Solve that pesky rear freeze plug problem once & for all!
Includes plate that bolts in place on the back of the block that takes place of the rear freeze plug.
Rear core plug plate for use in Common Rail Cummins blocks 2003 & up.
Plug Thread Size is 1/2" NPT.
**Install Note, PLEASE READ!**
This kit includes a high temperature Viton o-ring , care must be taken not to cut or damage the o-ring. The freeze plug bore must be cleaned with a wire brush or emery cloth to remove all rust and scale.
The freeze plug bore must have a small chamfer to allow for the o-rig to compress for a tight seal. Use motor oil to lube the o-ring and freeze plug bore, and then carefully install the freeze plug by hand being careful not to cut the o-ring. Does not use a hammer, the plug should slip in with hand pressure only.
