5.9/6.7 C OE Side Threaded Plug

Part: 5.9/6.7 C OE Side Threaded Plug

Part Number: 3690536

Manufacturer: Cummins

Description:

This Cummins part is a side threaded plug designed for 5.9L and 6.7L Cummins engines. This plug is used to seal off specific threaded openings on the side of the cylinder block or other parts of the engine, preventing leaks and ensuring the engine’s internal systems remain sealed and functioning properly.

The side threaded plug is used to seal threaded holes in the cylinder block or other engine components that are not in active use or do not require external connections. These holes are typically left open during manufacturing for manufacturing processes or future service connections. The plug ensures that there are no leaks of fluids (oil, coolant, etc.) from these points.

Typically made from durable steel or other high-strength metal, this plug is designed to resist high pressure, temperature fluctuations, and exposure to engine fluids like coolant, oil, and fuel.

It is designed for 5.9L and 6.7L Cummins engines, which are commonly found in light-duty trucks (e.g., Dodge Ram), medium-duty trucks, and various industrial equipment. This part is considered an Original Equipment (OE) part.

The plug is built to withstand the high pressure and temperatures that occur in the engine, ensuring that the seal remains intact even in demanding engine conditions.
