The Mazda 6/Atenza (MZR engine), a standout choice in the mid-size segment, has captivated New Zealand drivers with its combination of practicality and spirited driving dynamics. Since its debut from 2008 to 2012, it has established a loyal following among families and enthusiasts alike. In this guide, we’ll explore key maintenance insights, common concerns, and essential service recommendations to keep your Mazda 6 performing at its best.
Owners of the Mazda 6/Atenza with the MZR engine should be aware of potential issues that may arise, particularly as the vehicle ages. Potential problems include:
• Timing Chain Tensioner Wear: The timing chain tensioner can be prone to wear, especially around 100,000-150,000 km. Listen for any unusual noises from the engine.
• Oil Consumption: Some pre-facelift models have been known to exhibit oil consumption issues.
• DISI Turbocharger Failure (Turbo Models): If your Mazda 6/Atenza is equipped with a DISI turbocharger, be aware that premature failure is a possibility.
When taking your Mazda 6/Atenza for a Warrant of Fitness (WOF) inspection, be mindful of the following common failure points:
• Rust: Pay close attention to rust around the rear wheel arches, as this is a common area for corrosion.
• Steering Rack Play: Excessive play in the steering rack can lead to a WOF failure. Have the steering system inspected regularly.
• Headlight Clouding: Clouded or yellowed headlight lenses can reduce visibility and may result in a WOF failure. Polishing or replacement may be necessary.
The Mazda 6/Atenza provides an enjoyable ownership experience, and maintaining reliability is crucial as this vehicle ages. Regular servicing, ideally aligned with the recommended intervals, is key.
Maintenance Considerations:
• Scheduled Maintenance: Periodic service, including changes to automatic transmission fluid (ATF), is crucial. Regularly inspect engine timing components to proactively address any issues.
• Front End Components: Given the age, it’s wise to keep an eye on wear-prone parts like the drive shaft and wheel bearings. Quality wheel bearing grease can extend the life of your suspension system, which is essential for smooth driving.
• Braking System: Ensure your safety by routinely checking and replacing brake pads. This not only guarantees optimum performance but also peace of mind while driving.
• Cooling System: Around 150,000km, check the cooling system components, especially the radiator, water pump, and thermostat. These parts are critical for engine health and should not be overlooked. You can explore the necessary components in our Cooling section.
• Engine Components: Keep an eye on items like cylinder head bolts and crankshaft thrust washers, especially during major repairs or overhauls. These follow industry standards for durability and should be replaced as needed.
• Cabin Comfort: The fan speed resistor helps regulate your air conditioning system; a faulty one can lead to discomfort during drives. Always ensure wiper blades are fresh for maximum visibility in changing weather conditions. Discover more about our Wipers category.
