The engine number on a 2009 Honda Pilot is stamped into the engine block on the passenger side near the timing chain cover.
Because production variations exist, you may need to remove the engine cover or other nearby components to read it. The number identifies the specific engine build and is useful for service, parts lookup, and warranty records.
Where to look on the engine
These are the most common stamping locations for the 3.5L V6 (J35A) engine in the 2009 Pilot. Some vehicles may require removing covers or ducts to access the stamping.
- Front of the engine block on the passenger side near the timing chain cover
- Side of the block toward the bell housing (close to the transmission) if the front area is obstructed
- Under the plastic engine cover or near the intake plenum, after removing obstructing components
If you still cannot see the number after inspecting these areas, consult the service manual or contact a Honda dealer for the exact stamping location for your specific vehicle's build date.
How to read and record the engine number
Before attempting to read the stamp, prepare your workspace and ensure safety by letting the engine cool and clearing debris from the area.
- Turn off the vehicle and disconnect the negative battery cable if you plan to remove electrical components near the area.
- Remove the engine cover and any intake ducting or shielding that blocks access to the block surface.
- Clean the reading area gently with a rag to reveal the stamped characters on the block.
- Look for a stamped sequence of digits and letters; note the exact characters as they appear (including any hyphens or spaces).
- Record the engine number in your notes or a service file, and keep a photo for reference.
If you’re ordering parts or verifying compatibility, cross-check the engine number with Honda’s parts cross-reference or your service history to ensure accuracy.
