To avoid damaging the plug or pan, confirm the correct socket size before loosening the plug. The following steps help you verify the proper size for your specific vehicle variant.
Before using a list, note that the steps below are practical checks you can perform to verify the correct size for your Elantra.
- Inspect the current oil drain plug: look at the head to gauge the likely size and shape of the recess.
- Start with the most common size: attempt a 14mm socket first, turning gently to avoid stripping.
- If the 14mm socket does not engage or cannot loosen the plug, stop and consult the owner's manual or Hyundai service information for your exact engine variant to confirm the correct size.
Conclusion: While 14mm is the standard socket size for most 2020 Elantra oil drain plugs, verify with official documentation or the existing plug to account for any variations.
Practical tips for a smooth oil change
Aside from the socket size, prepare with the right tools: a drain pan, a compatible wrench or ratchet, gloves, and a new drain plug washer if required by Hyundai’s guidance for your engine variant. Always ensure the engine is cool before starting and follow Hyundai’s recommended oil change interval for your trim.
