3.7L V6 MZI - AWD
Petrol
While driving at low speeds, gently turn the wheel lock-to-lock; listen for any whining or groaning noises, as the power steering pumps on these V6 models are known to eventually show signs of wear.
During your inspection, carefully inspect the carpet near the front footwells for dampness, as the sunroof drains can sometimes become clogged, potentially leading to moisture buildup in these older units.
Shift through all gears while stationary and under light load; ensure the 6-speed transmission engages smoothly without hesitation, as these gearboxes benefit greatly from regular fluid changes.
Open the bonnet while the engine is running and listen for a persistent ticking sound; it is worth noting that while these engines are robust, they appreciate close attention to timing chain health as they reach higher kilometer milestones.
Consider a full cooling system flush and inspection of the radiator end tanks.
A good time to have a specialist check the engine mounts, as vibration can increase as these age.
Focus on suspension bushings and shock absorber performance to maintain that signature Mazda ride quality.
Ensure the engine oil is clear and filled to the correct level, as the 3.7L V6 runs best on high-quality synthetic oil.
Verify that the AWD system engagement is seamless by finding a quiet, loose-surface area to test the drive distribution.
Check the condition of the brake rotors and pads, as the weight of the CX-9 means these components work quite hard.
Inspect the cabin air filter and climate control system to ensure the vents are pushing air effectively for those colder NZ mornings.
Confirm the presence of a consistent service history, ideally performed by a specialist who understands the Mazda MZI engine architecture.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of the labour involved in accessing the front of the engine block. It is a vital piece of insurance for the 3.7L engine.
Depending on the car's history, you might eventually need to budget for refreshing the suspension arms and bushings, which will significantly improve the handling and comfort of the vehicle.
To keep the 6-speed automatic shifting as it did when it left the factory, planning for a transmission service is a proactive way to extend the life of the drivetrain.
