Most Dodge Challenger models use a 14 mm hex oil drain plug (socket size) with a typical M14 x 1.5 thread, but engine and year variations exist, so verify for your exact car.
Engine variants and typical sizes
The Challenger lineup spans several engines over its production years. While many share a common drain plug size, there can be exceptions based on the specific engine and model year. The following guidance reflects common configurations and should be used as a starting point; always confirm for your exact vehicle.
- 3.6L Pentastar V6 (the most widespread Challenger engine in earlier and later years): typically a 14 mm hex head drain plug with M14 x 1.5 thread.
- 5.7L Hemi V8: typically a 14 mm hex head drain plug with M14 x 1.5 thread.
- 6.4L (392) Hemi: typically a 14 mm hex head drain plug with M14 x 1.5 thread.
- 6.2L supercharged Hemi (Hellcat and variants): typically a 14 mm hex head drain plug with M14 x 1.5 thread.
These examples reflect the most common configurations found in modern Challengers. Variations can occur due to model-year updates or limited editions, so always double-check your vehicle’s manual or inspect the plug itself for confirmation.
How to verify the correct size for your car
To ensure you have the right size before performing an oil change, use these verification steps:
- Check the owner's manual or the official service bulletin for the exact drain plug specifications for your engine code and year.
- Inspect the existing drain plug on your car and measure the hex head size with a caliper or a socket to confirm whether it is 14 mm (most common) or another size.
- Cross-check the OEM part number for the drain plug in Mopar parts catalogs using your VIN to confirm the correct plug for your exact Challenger configuration.
- If in doubt, consult a qualified technician or dealership service department to avoid cross-threading or leaks.
Having the correct size reduces the risk of stripping the plug or damaging the oil pan and ensures a proper seal during the oil change.
Summary
In summary, the typical oil drain plug size for a Dodge Challenger is a 14 mm hex head (socket size) with an M14 x 1.5 thread, but there are engine- and year-specific variations. Always verify by checking the owner's manual, inspecting the current plug, or consulting official parts catalogs for your exact vehicle. A quick confirmation helps ensure a smooth oil-change process and a proper seal.
