The oil drain plug on most 2014 Ram 1500 models uses a 14 mm hex head and a metric M14x1.5 thread.
Engine variants and typical drain plug size
The 2014 Ram 1500 offered several engines, and the drain plug size is generally consistent across the lineup. Here are the typical specifications for the main engines in that year:
- 3.6L Pentastar V6 — drain plug head size typically 14 mm; thread usually M14x1.5
- 5.7L Hemi V8 — drain plug head size typically 14 mm; thread usually M14x1.5
- 3.0L EcoDiesel V6 — drain plug head size typically 14 mm; thread usually M14x1.5
In practice, a 14 mm socket will fit the majority of drain plugs on these engines, and the threads are the standard metric coarse type used on many Mopar oil pans. Always ensure the plug is clean and use the proper crush washer or gasket as specified for your oil pan.
How to verify the correct size for your truck
To confirm the exact drain plug size on your specific vehicle, follow these steps:
- Consult the owner's manual or service/repair manual for the exact drain plug specification and torque guidance.
- Inspect the existing drain plug: measure the hex across flats or test-fit a 14 mm socket to see if it fits cleanly without forcing.
- If the plug doesn’t fit a 14 mm tool, don’t force it—check the VIN-specific parts diagram or contact a dealer to confirm the correct size for your model year and engine.
Overall, most 2014 Ram 1500 models use a 14 mm head with M14x1.5 threads, but always verify on your vehicle to avoid cross-threading or damage during oil changes.
Summary: For the 2014 Ram 1500, the oil drain plug is typically a 14 mm hex head with M14x1.5 thread. This size covers the common engines in that year; always verify via the owner's manual or a VIN-specific parts diagram before removal or installation.
