I have a 2013 2014 Mazda CX5 skyactiv serpentine belt kit set for a 2013 20142.0 liter only skyactiv MAZDA CX5. The large belt goes around the crank, ac, alt. The short belt goes around the crank and the water pump.
As a car enthusiast I always try to use Original Equipment Manufactures parts. To me they seem to fit better which makes the repair process easier and in my experience normally outlast aftermarket copies. These belts easily went on my daughter’s CX-5 and fit exactly as originals.
