What size is the drain bolt on a 6.7 Powerstroke?
The drain bolt on the 6.7 Power Stroke oil pan is typically a 14 mm hex head with an M14x1.5 thread (a standard 14 mm oil drain plug). However, exact specs can vary by model year or pan revision, so it’s important to confirm with the factory manual or by inspecting the plug on your vehicle.
To understand the question in context: the oil pan drain bolt is the threaded fastener that seals the oil pan and allows the engine oil to be drained during an oil change. While many 6.7 Power Stroke engines use a common 14 mm/ M14x1.5 configuration, Ford has employed different pan revisions and aftermarket replacements over time. Relying on the vehicle’s manual, the VIN-specific workshop documentation, or the existing plug is the most reliable way to ensure you have the correct size and avoid cross-threading or leaks.
Common drain plug specifications
Use this list to understand the typical characteristics you’ll encounter when dealing with the 6.7 Power Stroke drain plug.
- Thread size: M14x1.5 (14 mm diameter, 1.5 mm pitch)
- Head type: 14 mm hex socket drive
- Often magnetic variants exist to collect metallic debris
- Material: steel with protective coating; some OEM plugs include a seal or washer
Knowing these common traits helps you select the right tool and spare parts for an oil change. If your plug differs from the above, consult the service manual or Ford dealer to get the exact specification for your VIN and oil pan revision.
How to verify on your vehicle
Before you start work, confirm the exact drain plug size for your truck to prevent damage or leaks during an oil change.
- Check the owner’s manual or the Ford workshop manual for the drain plug specification tied to your VIN. If you have access to Ford’s service databases (such as OASIS), use your VIN to pull the exact plug spec.
- Inspect the current drain plug: note the head size and measure the thread diameter with calipers if needed. A 14 mm socket should fit the head, and a thread gauge can confirm M14x1.5 if you’re unsure.
- If replacing, obtain an OEM drain plug that matches the documented spec (or an aftermarket plug with the same thread and seal requirements). Replace any sealing washer as required by the manual.
- Reinstall and torque to the Ford-recommended specification in your manual, using a torque wrench to avoid over- or under-tightening.
Following these steps will ensure the plug you install matches the engine’s needs and maintains proper oil sealing and drain performance.
What to do if you can’t confirm the size
If you’re unsure of your exact plug size and can’t access the manual, take these cautious steps to avoid damage or leaks.
- Bring the existing plug to a Ford dealer or reputable auto parts store to match the thread size and head type.
- Consult Ford OASIS or the VIN-specific service bulletin to verify the correct plug size for your year/model.
- Use a temporary magnetic drain plug with the same M14x1.5 thread size if you cannot locate an OEM plug immediately, and replace with the correct plug as soon as possible.
Proper verification minimizes the risk of cross-threading, stripping, or improper sealing during an oil change.
Summary
In most 6.7 Power Stroke applications, the oil pan drain plug is a 14 mm hex head with an M14x1.5 thread. Variations can exist across model years or aftermarket pans, so always verify with the vehicle’s manual or by inspecting the existing plug. When in doubt, consult Ford’s service documentation for your VIN and ensure you replace any gasket/seal and torques per the official spec.
