What size is the oil plug on a 2018 Ford Explorer?
The oil drain plug size for a 2018 Ford Explorer is a 14mm hex head (M14 x 1.5 thread). This is the most common specification for the model year across its two primary engines.
In 2018 the Explorer was offered with a 3.5L V6 and a 2.3L EcoBoost engine. While Ford typically uses a 14mm drain plug for these engines, there can be variations based on trim or production. To be certain, check your owner's manual, look for markings on the plug itself, or verify with a dealer or service manual.
Engine options in 2018 Explorer
The following engines were available in the 2018 Explorer, and they generally share the same drain plug sizing.
- 3.5L Ti-VCT V6
- 2.3L EcoBoost I-4
In practice, both engines commonly use the 14mm drain plug, but always verify on your specific vehicle as there can be exceptions.
How to verify the drain plug size on your Explorer
To confirm the plug size on your exact vehicle, follow these steps:
- Consult the owner's manual or the Ford service manual for the correct drain plug size and torque specification.
- Inspect the drain plug itself for markings such as M14 x 1.5 or a hex size indicated on the head.
- Use the correct tool: a 14mm socket or wrench to loosen and tighten the plug.
- If the plug head is damaged or overtightened, do not force it; use proper technique and consider replacing the plug or using a replacement drain plug with the correct thread size.
Once you know the correct size, keep a record for future maintenance and always follow the recommended torque when reinstalling to prevent leaks and strip damage.
Summary
The 2018 Ford Explorer typically uses a 14mm hex-head oil drain plug with M14 x 1.5 thread across its common engines (3.5L V6 and 2.3L EcoBoost). Verify on your specific vehicle by consulting the owner's manual or service documentation and use a 14mm socket for removal and installation.
