Replace all three accessory drive belts on Series 1 models with factory-correct genuine Mazda components, restoring reliable drive to the water pump, alternator and air conditioning circuits.
$120
This RX8 V-belt kit is the factory-correct replacement for all three accessory drive belts on Series 1 models. It covers the water pump, alternator and air conditioning drives in a single service-ready set.
Worn or cracked belts place uneven load on bearings. If the main belt fails, the result can be overheating and serious engine damage. Replacing with genuine Mazda parts removes that risk and restores every drive circuit to a confirmed, known-new condition.
For RX8 enthusiasts refreshing a Series 1, fitting fresh genuine belts pays back quietly. New belts restore steady, slip-free drive to the cooling and charging circuits. Belt squeal disappears and confidence returns across the full rev range. Replace at the first sign of any crack, do not wait for a belt to fail.
Complete the cooling refresh by fitting the GENUINE MAZDA OEM Radiator Hose Replacement Set at the same service interval. This brings all rubber cooling components to a known-new condition simultaneously. The BEATRUSH Engine Cooling Under Panel Tray channels airflow more effectively under the engine bay, supporting the cooling system this belt kit helps protect.

This genuine Mazda V-belt kit is designed for Series 1 RX8 models built from 2003 to 2008. It is not intended for Series 2 models. No modification is required for fitment on any Series 1 car.
The kit contains three belts, covering the water pump, alternator and air conditioning drives. Replacing all three in one service visit renews the complete accessory drive circuit at once.
These are genuine Mazda OEM belts, manufactured to the original tension and profile specification for the Renesis accessory drive. They seat correctly on OEM pulleys without modification.
On a Series 1 RX8, all three accessory belts share similar service exposure and age together. Replacing the set at once removes the risk of an overlooked belt failing shortly after, and gives you a confirmed baseline for the condition of every belt on the car.
Common indicators include squealing or chirping from the accessory drive, visible cracking or glazing on the belt surface, and intermittent charging or cooling irregularities. Belts of unknown service history are worth replacing regardless of appearance, since internal deterioration is not always visible.
Yes. The water pump shares the same accessory drive circuit as the belts, so the timing aligns well. Replacing both together avoids disturbing the fresh belts later if the pump needs attention, and keeps the cooling system fully renewed in a single visit.
The genuine Mazda belts are sized to the factory pulley dimensions. Compatibility with non-standard pulleys depends on whether those pulleys retain the original belt groove profile. If your pulleys match OEM dimensions, fitment should be straightforward.
Genuine Mazda components for older models like the Series 1 RX8 can become progressively harder to source as production runs end and dealer stock diminishes. Securing a new genuine set now ensures you receive parts that meet the original specification rather than relying on old stock of uncertain storage history.
