What size is the oil drain plug on a 2004 Dodge Ram?

The typical oil drain plug on most 2004 Dodge Ram pickups is a 14mm hex head with an M14x1.5 thread, meaning a 14mm socket fits the plug. Variations can occur between engine choices and oil pan designs, so verify for your specific truck.

Common engines and plug size

In the 2004 Ram lineup, the two most prevalent configurations were the 4.7L Magnum V8 and the 5.7L Hemi V8. Both generally use the same drain plug size, but differences in pan design or aftermarket parts can occur.

• 4.7L Magnum V8 — drain plug head size typically 14mm; thread pitch M14x1.5.


• 5.7L Hemi V8 — drain plug head size typically 14mm; thread pitch M14x1.5.

Note: Some 2004 Ram models with alternative configurations or aftermarket oil pans may differ. For exact specifications, consult the service manual or inspect the plug directly.

How to verify the exact plug size on your truck

To confirm the exact size on your specific vehicle, follow these steps:

1. Check the owner's manual or service manual for the recommended drain plug size and torque specification.


2. Inspect the oil pan where the drain plug sits to note the head size or markings on the plug.


3. Try the common sizes starting with a 13mm and then a 14mm socket, applying gentle pressure to avoid rounding off the head. If neither fits, seek professional guidance.

When replacing the drain plug, use the appropriate sealing washer if required, and torque to the manufacturer’s specification. Also replace the oil filter and use the correct oil grade for a complete oil-change procedure.

Summary

For most 2004 Dodge Ram models, the oil drain plug is a 14mm hex head with an M14x1.5 thread, applicable to the common 4.7L Magnum and 5.7L Hemi engines. Always verify against your specific engine and oil pan design by checking the manual or inspecting the plug itself, and follow proper torque and sealing guidelines during replacement.

What size socket is the oil drain plug?

There is no single socket size for all oil drain plugs, as it varies by vehicle, but common metric sizes are 13mm, 14mm, 15mm, 17mm, and 19mm. To find the correct size, check your vehicle's owner's manual or a set of assorted metric sockets if unsure.

Common sizes

• Metric: The most common sizes for passenger vehicles are between 13mm and 17mm. 
• SAE: Some older or specialty vehicles may use SAE (inch) sizes, which are often fractional (e.g., 3/8" or 1/2"). 
• Specialty: Some plugs might have a square opening, a hex (Allen/Allen key), or a Torx (star) shape instead of a traditional bolt head. 

How to find the right size

1. Check your owner's manual: This is the most reliable source for your specific car. 
2. Use a socket set: Start with common sizes like 13mm, 14mm, 15mm, and 17mm. A 6-point socket is best as it grips the bolt head more securely. 
3. Visit an auto parts store: You can tell them your vehicle's make and model, and they can look up the correct size. 
4. Try a universal set: If you frequently change the oil, consider buying a specialized oil drain plug socket set that includes common metric and SAE sizes.

Socket size

• 13 mm: This is the standard size for most modern RAM 1500 trucks, including those with the 5.7L Hemi, 3.6L Pentastar, and 3.0L EcoDiesel engines. 

Important considerations

• Older models: Some older models may use a 17 mm socket, so it's a good idea to verify the size on your specific vehicle if you are unsure. 
• Torque: After reinstalling the plug, tighten it to the manufacturer's specification (often around 25 ft-lb for the 5.7L Hemi) using a torque wrench. 
• Replacement plug: The drain plug itself has an M14 x 1.50 thread size. If the threads on the old plug are damaged, you will need a new one.
