How to Verify Compatibility Using Your Engine Serial Number
Volvo Penta engines include an identification plate that lists the engine model and serial number.
Typical locations include:
-
On the engine block near the thermostat housing
-
On the valve cover
-
On the engine mounting bracket or timing cover
To confirm the correct belt:
-
Locate the engine model and serial number on the engine data plate.
-
Check the Volvo Penta parts catalog for your specific engine serial number range.
-
Confirm that V-belt 966903 is listed for that engine configuration.
Because accessory setups may vary by engine revision and serial range, verifying the serial number ensures the correct belt length and fitment.
