Description

Keep every belt-driven accessory spinning with the Gates Serpentine Belt K030315SF. This single, multi-rib belt loops over the engine's accessory pulleys — including the water-pump pulley — to transfer rotation from the crankshaft to the driven components. It installs as a direct-fit replacement across a wide range of Mazda applications: the 2014-2022 Mazda 3, 2014-2017 and 2019-2022 Mazda 3 Sport, 2014-2021 Mazda 6, 2014-2025 Mazda CX-5, 2024-2025 Mazda CX-90, 2016-2024 Mazda MX-5, and 2016-2024 Mazda MX-5 Miata.

Water-pump drive: routes over the water-pump pulley as part of the serpentine accessory-drive path on the listed applications.
Direct-fit replacement: fits the listed Mazda applications.
Signs it may need replacing: belt squeal, visible cracking, glazing, or fraying of the ribbed surface.

If a worn or cracked belt is behind your noise or accessory-drive issue, this replaces it. Always inspect the tensioner and pulleys when fitting a new belt.
