The serial number on a Honda GX160 is stamped into the engine’s crankcase or shown on a small identification plate fixed to the side of the block. The most common spots are on the left side near the recoil starter or on the right side near the carburetor.
GX160 engines come in several variants used in generators, pressure washers, and other equipment. Because production runs and sub-models can differ, the exact location may vary slightly. If you don’t see a plate in the first place you check, inspect both sides of the crankcase and look behind the carburetor mounting area for stamped numbers.
Common locations on GX160 engines
To help you locate the serial number quickly, check these typical spots that Honda uses across GX160 variants.
- Left side of the crankcase near the recoil starter housing
- Right side of the crankcase behind the carburetor mounting flange
- On a metal identification plate affixed to the side of the engine block
If you don’t find a plate, look for a stamped number directly on the crankcase casting in one of these areas.
How to read and record the serial number
Once you locate the serial number, follow these steps to photograph and document it for service, parts, or warranty needs.
- Clean the area around the number to improve readability
- Copy the exact digits and letters, including any hyphens or prefixes
- Note the model number (GX160) and any sub-model or production code
- Take a clear photo from straight on for reference
Having an accurate record of the serial number helps ensure you get the correct parts and service.
What to do if you still can’t locate it
If you cannot find the serial number after inspecting the common locations, consult the owner’s manual for your specific GX160 variant or contact Honda customer support or an authorized dealer. Provide the model (GX160) and your approximate build year to receive targeted guidance.
Summary
The GX160’s serial number is usually stamped on the crankcase or shown on a metal plate on the engine block, with the most frequent spots being the left side near the recoil starter or the right side near the carburetor. If needed, check both sides and refer to the manual or dealer for confirmation. Recording and safeguarding this number facilitates parts orders, warranty claims, and service requests.
