The 5.9 and 6.7 suffers from freeze plug failures, more correctly, they blow out causing a massive coolant leak, leading to an overheated engine if not caught quickly. The CHOATE Cummins Billet Blow Proof Freeze Plugs eliminate the failure prone factory original stamped metal plugs in favor of a bolt in billet aluminum high-end plug.
These plugs will not blow out like the stock ones nor will they corrode away. Comes with five 6061 Aluminum plugs, Buna o-rings, and stainless steel hardware.
Make sure to run the proper amount of antifreeze necessary, especially in cooler climates.
