The 6.7 Cummins radiator drain plug is essential for draining coolant from the radiator during maintenance. Understanding its location and how to access it can save time and prevent messes.

Drain Plug Location

The drain plug for the 6.7 Cummins engine is typically located on the driver's side of the radiator, near the bottom. Here are the steps to locate and access it:

  • Position: Look for the drain plug on the driver's side, just below the radiator.

  • Accessing the Plug: You may need to move some components out of the way to reach it. Common methods include:

- Removing the power steering reservoir by unbolting it.

- Accessing through the wheel well by removing the inner fender liner.

- Alternatively, you can remove the grille for better visibility and access.

  • Type of Plug: The drain plug usually requires a special tool, often an Allen wrench or a socket wrench, depending on the model year.

Draining Procedure

To properly drain coolant from your 6.7 Cummins radiator, follow these steps:

1. Prepare Your Tools: You will need a bucket to catch the coolant, an Allen wrench (often 3/8” or 10mm), and possibly pliers for better grip.

2. Locate and Remove the Plug:

- Turn the drain plug counterclockwise until coolant starts flowing out.

- If needed, use pliers to help grip and turn the plug if it's difficult to access.

3. Catch Coolant: Ensure your bucket is positioned correctly to catch all draining coolant to avoid spills.

4. Reinstalling: After draining, reinstall the plug by hand and tighten it securely with your tool.

Important Considerations

  • Always ensure that your engine is cool before attempting to drain coolant to prevent burns.

  • Dispose of old coolant properly, as it is hazardous to pets and wildlife.

  • After draining, consider flushing the system if you are changing coolant types or if it has been a long time since your last service.
