3.7L V6 MZI - FWD
Petrol
Test drive task: Find a quiet, flat road and listen closely during slow-speed turning. | Observation: With these larger SUVs, check for any clicking or clunking sounds from the front end, as the CV joints and lower control arm bushings can wear over time given the vehicle's weight.
Test drive task: Gently accelerate and decelerate through the gears while keeping an eye on the tachometer. | Observation: Be mindful of any hesitation or 'shuddering' when the transmission shifts; smooth operation is key, and it is worth noting the transmission fluid condition.
Test drive task: Park the car and leave it running for a few minutes, then check underneath. | Observation: It is worth peering for any signs of weeping from the Power Transfer Unit (PTU) or differential areas, as seals on vehicles of this vintage can occasionally show their age.
Test drive task: Operate the climate control through all fan speeds and zones. | Observation: Confirm the air conditioning blows cold consistently; sometimes the blend door actuators can become a little stubborn or sticky on models with higher mileage.
Consider a full transmission fluid flush and a thorough inspection of suspension bushings.
Typically the stage where spark plug replacement is recommended for this 3.7L V6 to maintain peak efficiency.
Check the water pump and cooling system components for peace of mind as the vehicle settles into higher mileage.
Keep a regular eye on the engine oil level between services, as it is good practice with these larger V6 powerplants.
Ensure the cooling system is flushed on schedule to protect the radiator and cooling hoses.
Listen for any unusual noises during cold starts, which helps keep track of the engine's health.
Regularly rotate the tyres to manage wear, as the CX-9's weight can be a bit demanding on rubber.
Keep the cabin air filter fresh to ensure the climate control system remains efficient and the air remains clear.
Estimated repair costs if issues arise
If the ride starts feeling a bit less 'planted' than when new, you might eventually need to budget for refreshing the front control arm bushings or struts to restore that signature Mazda handling.
Because the water pump is tucked away, it is a prudent future budget planning move to address it if the car reaches higher mileage, ensuring the cooling system stays robust.
To keep that 3.7L V6 running smoothly, you might find that after a decade of service, the ignition system may eventually require a refresh to maintain optimum fuel economy and performance.
