The marking on the back of a timing belt is the most reliable way to identify the correct replacement. This Optibelt belt is coded 50 AT5K6 / 12000 AFX, with an AT5 profile, a 12000 mm length and a 5 mm pitch. Read the old belt before ordering to confirm these values match your drive.
The code 50 AT5K6 / 12000 AFX combines the profile and the length. The AT5 profile and 5 mm pitch define the tooth geometry, while 12000 mm is the belt length. If your existing belt is worn or the marking is faint, clean the back of the belt and check it under good light. A photo of the marking helps us confirm the part number when you request a quote.
