Conti V-Belt - 10x925mm - V-belt (commonly cross-referenced as AVX10x925, 9.5x925, or 15365 in SAE/inch sizing) fits select 1965–1993 US-market vehicles, notably Volvo 240-series sedans and wagons, Nissan D21 Hardbody pickups and Pathfinders, classic air-cooled Porsches, and early-1980s GM passenger cars.

Understanding Cutoff Dates & Sizing
- Pulley & Engine Cutoffs. On the 1983 Buick Century, fitment depends on pulley diameter—only vehicles equipped with the 5 9/16-inch A/C pulley take the 10x925 belt. On the Nissan Pathfinder, 1988 is the final cutoff year because Nissan discontinued the 2.4L 4-cylinder engine in the US Pathfinder lineup for 1989.
- Matched Pair Requirement. Both the Volvo 240 and Nissan Z24 2.4L use two identical 10x925 belts side-by-side to drive the alternator and water pump. Always replace them in matched sets (
10X925SET) so one belt does not stretch faster than the other.
- Metric vs. Imperial Sizing. A 10x925 belt measures 10 mm wide (3/8" / SAE 15-series) by 925 mm outside circumference (36.42 inches). In standard North American parts catalogs, it cross-references to 15365 (15/32" top width, 36.5" length) and 9.5x925.
