Petrol
While driving at low speeds, cycle the 4WD selector through its modes; in cars of this age, it is common to check that the transfer case engages and disengages smoothly without mechanical clunking.
Check this by starting the engine from cold and listening carefully to the front of the block; you might eventually observe a rattling sound which can indicate that the timing chain tensioner requires attention in the future.
While the vehicle is idling, shift between Park, Drive, and Reverse; if you notice a significant delay or a 'thump,' it may suggest that the transmission mounts or fluid levels could benefit from a professional review.
During your test drive on a varied road surface, pay attention to any wandering or light knocking from the front end; the Rexton is a heavy SUV, and it is common for suspension bushes or ball joints to show wear over time.
Plan for a comprehensive spark plug replacement and a thorough inspection of the cooling system, including the thermostat and water pump.
Consider a full transmission fluid flush and a refresh of the differential and transfer case oils to maintain drivetrain longevity.
At this stage, it is wise to budget for a deep-dive into the suspension system, specifically checking the shock absorbers and rubber bushings for fatigue.
A proactive check of the timing chain stretch and the health of the fuel injectors is recommended to ensure the I6 engine continues to run efficiently.
Verify the service history for regular oil changes using high-quality synthetic oil to protect the Mercedes-derived straight-six engine.
Inspect the valve cover gasket for any signs of weeping, as keeping the top end dry helps protect surrounding electrical components.
Check the condition of the radiator and coolant hoses for any signs of aging or brittleness common in older NZ vehicles.
Confirm that the air conditioning system blows cold and that the cabin filter has been replaced to ensure comfort during NZ summers.
Test all electronic seat adjustments and window regulators to ensure the interior convenience features remain fully functional.
Estimated repair costs if issues arise
Depending on the car's history, you might eventually need to budget for this job to prevent chain slack; it involves significant labor to access the front of the engine.
If this component needs attention in the future, a full service including the electronic 'conductor plate' connector is a standard proactive measure for this gearbox type.
In cars of this age and weight, the rubber components in the front end naturally perish; replacing these will restore the original steering precision.
Future budget planning should include a refresh of the cooling components to avoid overheating risks during long-distance towing or summer trips.
