Engine number

The letter designation and engine number are on the sticker (arrow) (see fig. VC 2.001), located on the toothed belt cover.



Engine number contains up to nine characters (alphanumeric). First part (maximum 3 letters) - letter designation of the engine, the second part (six-digit) - serial number. After the production of more than 999,999 engines with the same letter designation, the first digit of six digits.
