Parts for your 2019 Subaru Outback-Drive belt tensioner

2019 Subaru Outback drive-belt tensioner

Technical sources confirm the 2019 Subaru Outback is fitted with a drive-belt tensioner on the main accessory (serpentine) belt. The Subaru factory service manual (Subaru Tech Information System – Drive Belt sections for FB25 and EZ36) details a spring‑loaded automatic tensioner used to set and maintain belt load. Subaru’s parts catalogue lists a “belt tensioner assembly” for both 2.5i and 3.6R variants, and major aftermarket catalogues (Gates, Dayco) specify replacement tensioners for this model. Note: on many 2.5i Outbacks the A/C uses a separate stretch‑fit belt without its own tensioner
