What size is a Dodge Ram 1500 oil drain plug?
In most Dodge Ram 1500 pickups, the oil drain plug is a 14mm drain plug with M14x1.5 threads and a 14mm hex head. However, some engines or model years can vary, so verify the size on your specific truck.
The Ram 1500 lineup includes several engines across generations, such as the 3.6L Pentastar, the 5.7L Hemi, and the 3.0L EcoDiesel. While a 14mm/M14x1.5 drain plug is common on modern Mopar engines, variations can occur. This article explains how to confirm your exact size and what to do if you encounter a different specification.
How to verify the correct drain plug size
To determine your exact drain plug size, use these steps:
- Consult the owner's manual or a service manual for your exact model year and engine code. The manual will specify the drain plug size, thread pitch, and torque spec.
- Inspect the existing drain plug: a 14mm hex head is common on Mopar engines; if the socket that fits the plug is 14mm, it is likely a 14mm plug. Measuring the head with a caliper or trying a 14mm socket can help confirm.
- Measure or cross-reference the thread diameter: if you can access the threads, a metric M14x1.5 is typical for many Ram 1500 engines; you can also bring the plug to an auto parts store to match a replacement.
- Ask a professional or reference official Mopar resources for your VIN/engine code, as some configurations may require a different size or thread.
When replacing, use the correct thread size and a new crush washer or gasket if required, and follow the recommended torque specification in the manual.
Engine and year variations
Across generations, most Ram 1500s use a drain plug with a 14mm hex head and M14x1.5 threads. However, older or specialized configurations (certain early years or non-standard engines) might use a different size. Always verify with your exact VIN and engine code to avoid mismatched plugs.
Summary
The drain plug size on a Dodge Ram 1500 is usually 14mm with M14x1.5 thread and a 14mm hex head, but variations can occur by engine and year. Verify with the owner's manual or by inspecting the old plug, and torque to the official specification when replacing.
