5.9/6.7 C OE Freeze Plug

Part: 5.9/6.7 C OE Freeze Plug

Part Number: 3945094

Manufacturer: Cummins

Description:

The 5.9/6.7 Cummins OE (Original Equipment) Freeze Plug is an essential component for Cummins 5.9L and 6.7L diesel engines, commonly found in light-duty to medium-duty trucks, such as the Dodge Ram. Freeze plugs (also known as core plugs or expansion plugs) are used to seal the openings in the engine block where sand cores are removed during the casting process.

The primary role of the freeze plug is to prevent the engine block from cracking in the event that coolant freezes. The freeze plug is designed to pop out when the coolant inside the engine block freezes and expands, thus relieving pressure and preventing damage to the engine block.

Typically made of steel or brass, the plug is durable and resistant to corrosion and extreme temperatures.

Specifically designed to fit the engine block of the 5.9L and 6.7L Cummins engines, these freeze plugs are part of the OEM (Original Equipment Manufacturer) supply.

Freeze plugs are typically installed in the engine block at the factory, but they can also be replaced if necessary, usually during an engine rebuild or if a freeze plug is damaged.
