SKU: XD339


Don’t let a blown freeze plug cause your 2003-2018 Dodge 5.9L and 6.7L Cummins to overheat, fix the issue before it happens with the XDP HD Bolt-On Freeze Plug (Rear) XD339. Hard acceleration, increased engine RPM, and temperature differences in your cooling system can cause the rear freeze plug to blow out.

Not only can a blown out freeze plug leave you stranded, it also causes large coolant losses that lead to overheating conditions.

The XDP HD Bolt-On Freeze Plug (Rear) XD339 fastens securely to your engine block using existing bolt holes. Each freeze plug is machined from 6061 aluminum and features a built-in o-ring for a leak-free seal.

This freeze plug does not require transmission removal for installation and is pre-drilled and tapped to 1/2 inch NPT to work with most coolant bypass kits (1/2 inch NPT plug not included).
