Check the transmission shift quality by gently accelerating from a standstill. | Advice: In fifth-generation Explorers, it is common to notice hesitant gear changes; ensure the transmission shifts smoothly through all gears as this can indicate internal wear.
Listen for any whining or groaning noises during low-speed steering maneuvers. | Advice: The Power Transfer Unit (PTU) is a hardworking component in these AWD models, and monitoring for unusual sounds helps in assessing its long-term health.
Observe the digital dashboard and infotainment screen for any flickering or non-responsive touch inputs. | Advice: Electronic gremlins can occasionally appear in models of this age, so testing the full functionality of the MyFord Touch system is a sensible precaution.
Run the air conditioning on full cold and full heat while stationary. | Advice: Testing the blend door actuators ensures that the climate control system can move between temperatures correctly without clicking or failing to adjust.
Consider a full transmission fluid service and inspection of the suspension bushings.
Keep an eye on the water pump status, as it is internally mounted on the 3.5L Duratec engine.
Evaluate the condition of the drivetrain components and check for any signs of play in the steering linkages.
Prioritize regular oil changes every 10,000km using the manufacturer-recommended synthetic oil to protect the engine internals.
Inspect the coolant levels frequently to ensure the cooling system is performing optimally for the 3.5L V6 engine.
Keep the cabin air filter fresh, especially if you drive on dusty NZ backroads, to maintain good airflow.
Verify that the wheel alignment is checked annually, as this helps prevent uneven tyre wear on such a heavy vehicle.
Ensure the brake fluid is flushed every two years to maintain consistent stopping performance.
Estimated repair costs if issues arise
Because the water pump on the 3.5L Duratec is internal and driven by the timing chain, it is a significant job to access. If you notice any coolant leaks near the engine block, you might eventually need to budget for a major service that includes replacing the pump and associated seals.
The PTU can be prone to overheating fluid over time. If you plan on keeping the vehicle for the long haul, it is wise to plan for a service or rebuild to ensure the AWD system remains reliable.
Given the Explorer's weight, components like control arm bushings and struts often show wear after several years of NZ road use. Setting aside a contingency fund for a suspension refresh will keep the ride feeling firm and safe.
