This Dayco Drive Belt Tensioner replaces the original equipment unit on Mazda CX-5 2.5L Petrol AWD models built from 2020 to 2023. Expect a service life of around 90,000km under normal Australian conditions. Profile is 4-rib Micro-V with an effective length of approximately 2100mm. Inspect the tensioner and idler bearings whenever the belt is replaced; they wear at a similar rate. Rib depth is held to tight tolerance so the belt tracks correctly on the tensioner and idler pulleys. The Aluminium construction resists cracking, glazing and the noise that comes with a stretched belt. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Fitting is a straightforward workshop job and no coding or calibration is needed. New stock, 12 Months warranty, and dispatched from our Australian warehouse.
