What size is the oil drain plug on a 2013 Dodge Durango?
The oil drain plug on a 2013 Dodge Durango is a standard metric plug with M14 x 1.5 thread and a 14 mm hex head. Most Durango models from this year use a 14 mm socket to remove and reinstall the plug.
Size and specifications
Before listing the exact dimensions, here are the key size-related details you’ll encounter when performing an oil change on a 2013 Durango.
- Thread size: M14 x 1.5
- Drain plug head size: 14 mm (requires a 14 mm socket)
- Washer: copper or aluminum crush washer is typically used and should be replaced on reinstallation
- Torque for reinstall: approximately 25–30 Nm (18–22 ft-lbs)
- Common engines in the 2013 Durango (3.6L V6 and the 5.7L Hemi) generally use the same drain plug size
Replacing the crush washer and following the recommended torque helps ensure a proper seal and prevents leaks. If you’re working from a dealer or aftermarket service manual, confirm the exact specification for your engine variant.
Engine variations and verification
Common engines for the 2013 Durango
In 2013, the Durango offered multiple powertrains, most notably the 3.6L V6 Pentastar and the 5.7L Hemi V8. For both engines, the drain plug size is typically the same metric standard (M14 x 1.5) with a 14 mm hex head, but it’s always wise to verify against your specific vehicle’s service documentation or by inspecting the plug itself if you’re unsure.
- 3.6L V6 Pentastar
- 5.7L Hemi V8
When in doubt, consult the owner’s manual, the factory service manual, or a trusted mechanic to confirm the exact plug size and torque for your exact VIN and engine variant.
Practical tips for replacing the drain plug
Guidance to help you perform an oil drain plug job correctly and safely.
- Prepare your tools: 14 mm socket, ratchet, drain pan, fresh crush washer, and approved grade motor oil for your Durango’s engine.
- Warm up the engine briefly to loosen old oil, then place the drain pan under the oil pan drain plug.
- Carefully unscrew the plug and allow oil to drain completely, then clean the plug and mounting area.
- Install a new crush washer on the drain plug and thread the plug back in by hand to avoid cross-threading, then tighten to the recommended torque of about 18–22 ft-lbs (25–30 Nm).
- Refill with the correct amount and grade of oil, then check for leaks after running the engine briefly and rechecking oil level.
Always replace the crush washer during oil changes, and avoid over-tightening, which can strip the threads or warp the oil pan. If you notice leaks after a change, recheck torque and washer seating promptly.
Summary
For a 2013 Dodge Durango, the oil drain plug generally uses a 14 mm hex head with an M14 x 1.5 thread. Replace the crush washer and tighten to approximately 18–22 ft-lbs (25–30 Nm). Always verify by checking your specific engine variant (3.6L V6 or 5.7L Hemi) against the service manual or dealer guidance, and consult the manual if you’re unsure.
