How to Verify Compatibility Using Your Engine Serial Number

Volvo Penta engines include an identification plate showing the engine model and serial number, which is required to confirm correct replacement parts.

Typical locations for the engine identification plate include:

On the engine block near the thermostat housing
On the valve cover
On the timing cover or engine mounting bracket

To confirm the correct belt:

Locate the engine model and serial number on the engine identification plate.
Check the Volvo Penta parts catalog for your specific engine serial number range.
Confirm that V-belt 966694 is listed for your exact engine configuration.

Accessory drive systems can vary by engine revision, alternator size, and serial number range, so verifying the serial number ensures the correct belt length and fitment.
