2019 Subaru Legacy (Liberty) drive-belt: what it does and when to replace it

Yes, a drive-belt is absolutely used on the 2019 Subaru Legacy (called Liberty in Australia). Subaru’s official 2019 Legacy/Outback Service Manual (Engine, FB25/EZ36 “Drive Belt” section), the Subaru Genuine Parts Catalogue for MY2019, and the factory Maintenance Schedule all list and describe an accessory/serpentine drive-belt with an automatic tensioner for this model. Both engines offered that year—the 2.5‑litre FB25 and the 3.6‑litre EZ36—use a single external belt to spin accessories. These engines run timing chains internally, so the drive-belt isn’t for cam timing
