This genuine Mazda replacement set covers every accessory drive belt on the 2009-2012 RX8 Series 2. The kit includes the water pump and alternator belt and the dedicated air conditioning belt. Cracked or glazed V-belts are a common service item on ageing RX8s. Sourcing them as a matched genuine set removes the guesswork from a scheduled refresh.

RX8 Series 2 Belt Kit Features

  • Complete matched set supplies both required V-belts in one kit, eliminating piecemeal sourcing for the Series 2 accessory drive.
  • Each belt is produced to OEM specifications. Material, dimensions and tension profile match the factory arrangement exactly.
  • The included water pump alternator belt drives two critical systems simultaneously, making its condition essential to routine servicing.
  • A separate air conditioning belt is included for the Series 2 A/C system, which runs its own dedicated drive.
  • Finally, buying new genuine Mazda V-belts means every belt has a known service history, no uncertainty about age, heat cycles or prior stretching.

For RX8 enthusiasts, this RX8 Series 2 belt kit is the practical foundation of any thorough accessory-drive refresh. Fitting it during a cooling-system service keeps everything factory-correct in one visit. New belts restore confident drive to the water pump and alternator from the first start.

Inspect the rest of the cooling circuit at the same time. Pair this belt kit with the GENUINE MAZDA OEM Radiator Hose Replacement Set to renew the coolant passages alongside the drive.

If a full cooling upgrade is on the agenda, add the AUTOEXE x KOYORAD High-Capacity 48mm Aluminium Radiator. Its high-capacity aluminium core complements a freshly serviced drive system. Mazda’s official Australian site provides further ownership and servicing information.

Frequently Asked Questions

Which RX8 models does this belt kit fit?

This genuine Mazda belt kit is designed specifically for the RX8 Series 2, covering cars built from 2009 to 2012. It does not suit the earlier Series 1 RX8, which uses a different accessory-drive arrangement.

How many belts are included in the kit?

The kit includes two V-belts: one accessory drive belt that serves the water pump and alternator, and a dedicated belt for the air conditioning system. Both belts required for the Series 2 accessory-drive layout are covered in a single purchase.

Why buy a matched kit rather than sourcing the two belts separately?

Buying the matched kit means both belts are factory-correct Mazda parts from the same source, removing the need to hunt down the water pump-alternator belt and the air conditioning belt individually. It also ensures you have everything needed to complete the accessory-drive service in one go.

Are these genuine Mazda parts or aftermarket replacements?

These are genuine Mazda OEM V-belts, not aftermarket substitutes. They are manufactured to the same specification as the belts fitted at the factory, ensuring correct dimensions, tension characteristics and fitment for the Series 2 RX8.

How often should the accessory drive belts be replaced on a Series 2 RX8?

Belt replacement intervals are specified in the Mazda service schedule for the Series 2 RX8. Belts showing visible cracking, glazing or fraying should be replaced promptly regardless of mileage, as a snapped belt can disable the water pump or alternator mid-drive.

What other components should I inspect or replace at the same time as the belts?

While the accessory drive is apart, it is a sensible opportunity to inspect cooling-system components. Replacing the thermostat and radiator hoses at the same service interval avoids disturbing the cooling system a second time and keeps the entire circuit in a known condition.

Why fit new genuine belts rather than reusing the old ones if they look okay?

Rubber belts degrade internally before visible cracking appears, and a used belt of unknown service history carries real risk. New genuine Mazda belts restore a known-condition baseline and give confidence in the accessory drive for the next service interval.
