The oil pan bolts on a 2006 Honda Odyssey are typically M6 x 1.0, about 8–10 mm long. Always verify against your vehicle’s service manual or by inspecting the existing bolts, since production runs or replacements can vary.
Understanding the bolt size for this model
For the 2006 Odyssey, which uses the J35A 3.5-liter V6 engine, the oil pan is secured with small-diameter fasteners. The most common specification is a metric M6 thread with a 1.0 mm pitch, paired with a short bolt length to ensure a proper seal with the gasket and pan flange.
Key details to know before you replace bolts:
- Thread size: M6 (6 mm diameter) with 1.0 mm pitch
- Common bolt length: 8–10 mm (some locations may use slightly longer bolts)
- Drive type: refer to the existing bolts (often hex/Allen or hex head) for the proper driver
- Material: steel; use OEM or high-quality replacement bolts to maintain torque and sealing
Bottom line: M6 x 1.0 is the typical oil pan bolt size for this model; confirm with the service manual or by measuring the current fasteners to ensure exact size and length.
How to verify the exact size on your vehicle
Because bolt sizes can vary by production run or aftermarket parts, use one of these verification methods:
- Consult the Honda 2006 Odyssey service manual (engine section) for the oil pan bolt specification
- Remove a bolt and measure its diameter with calipers and its thread pitch with a thread gauge to confirm M6 x 1.0 or another size
- Check OEM bolt part numbers for the oil pan bolts; replacements are typically M6 x 1.0 with the correct length
If you cannot access the manual, contact a Honda dealer or a certified shop to confirm the exact bolt specification for your VIN.
Summary
For a 2006 Honda Odyssey, the oil pan bolts are generally M6 x 1.0 with a short length around 8–10 mm. Always verify against the service manual or by inspecting the current fasteners to ensure you get the correct size before replacement or reinstallation.
