• MAZDA 6 (mid‑size sedan)
• MAZDA CX‑5 (compact SUV)
• Other Mazda vehicles with the same belt tooth configuration

Engineers have verified that the kit matches the original specifications for tooth count, pitch diameter, and tension requirements, ensuring seamless integration.

Performance Advantages

• Enhanced Durability – The reinforced belt material resists wear and tear, extending service life beyond standard OEM belts.
• Improved Timing Accuracy – Precise tooth alignment reduces timing drift, maintaining optimal fuel efficiency and engine performance.
• Reduced Noise & Vibration – High‑quality bearings and tensioners minimize belt noise, contributing to a quieter cabin experience.
• Heat Resistance – The composite construction withstands high operating temperatures without compromising flexibility or strength.
• Easy Installation – All components are pre‑assembled where possible, and the included manual simplifies the process for both professionals and DIY enthusiasts.

Installation Overview

1. Preparation: Disconnect battery, remove engine cover, and access the timing belt area. Ensure all tools are ready.
2. Remove Old Belt: Loosen the tensioner, slide the old belt off pulleys, and discard it safely.
3. Install New Pulley Set: Mount each pulley onto its respective shaft, tightening bolts to manufacturer torque specifications.
4. Mount Tensioner: Position the new tensioner on the crankshaft, ensuring proper alignment with the belt path.
5. Lay the Belt: Route the new timing belt around all pulleys following the diagram in the manual. Verify that the belt sits correctly on each gear tooth.
6. Tension Adjustment: Activate the tensioner to apply correct belt tension, checking for slack or over‑tightening.
7. Final Checks: Rotate the engine by hand in 90° increments to confirm that all components move smoothly and no interference occurs.
8. Reassembly: Replace the engine cover, reconnect battery, and perform a short test drive to ensure proper operation.

Maintenance Tips

• Inspect the belt for cracks or fraying after every major service interval.
• Check tensioner operation periodically; replace if it shows signs of wear.
• Avoid over‑tightening bolts on pulleys to prevent shaft damage.
• Keep the engine bay clean and dry to protect belt components from moisture and debris.
