The oil pan bolts on a 2018 Honda Pilot are metric M6 bolts (M6 x 1.0) and are typically about 12 millimeters long. This size is what owners and mechanics commonly encounter when servicing the oil pan on this model.
On the 2018 Pilot with the 3.5-liter V6 engine, Honda uses multiple M6 fasteners around the oil pan. Sizes can vary slightly by production year or regional specification, so it’s wise to verify against your vehicle’s service data if you’re replacing fasteners.
Bolt size basics for the 2018 Honda Pilot
The following attributes are the most relevant when identifying or replacing the oil pan bolts. Variations are possible, but the standard spec is widely used across markets for this model year.
- Thread diameter: M6
- Thread pitch: 1.0
- Bolt length: approximately 12 mm
These characteristics cover the majority of oil pan bolts on the 2018 Pilot. If you’re replacing or stocking up, start with M6 x 1.0 x ~12 mm bolts and confirm with official data for your VIN if needed.
How to verify the exact bolt size on your vehicle
To ensure you’ve got the correct fasteners, follow these steps before purchasing replacements:
- Inspect a remaining OEM oil pan bolt or the bolt remainder in the pan to gauge diameter and thread pitch
- Measure with calipers or compare to a known M6 x 1.0 bolt from a parts supplier
- Consult the Honda service manual or a dealership for VIN-specific fastener data
- When replacing, use bolts of the correct length so they engage properly without protruding into the oil pickup or engine internals
Verifying the precise size helps prevent oil leaks or mechanical damage during maintenance.
Summary
For a 2018 Honda Pilot, the oil pan bolts are typically M6 x 1.0 and about 12 mm long. Always confirm against the service manual or a dealer for your VIN, as factory revisions can occur.
