Timing Belt vs Serpentine Belt: OE and Application Checks
A belt request should identify the drive system before a supplier matches an OE reference. A timing belt and a serpentine belt serve different systems, use different routing information and should not be quoted as interchangeable.
Confirm the belt system
Record whether the request concerns the timing drive, accessory drive, or a related tensioner and idler component. Keep the belt and any kit contents separate unless the applicable catalog confirms a complete supplied set.
Match the OE number to the engine
Check the exact OE reference, engine code, displacement, production range and vehicle market. Where the catalog provides more than one belt length or tooth profile, do not infer the correct version from a model name or photograph alone.
