3.7L (PowerTech V6) - Laredo
Petrol
Check the transmission performance by accelerating steadily from a stop. Notice if there is any hesitation or 'hunting' for gears, as the NAG1 transmission can occasionally develop solenoid issues in older units. | Advice: Ensure the fluid is bright red or translucent; dark or burnt-smelling fluid is a sign to inquire about service history.
Turn the steering wheel fully to both locks while at a standstill. Listen for any groaning sounds from the power steering pump, a common component that can become noisy as the vehicle approaches higher mileage. | Advice: If you hear a whine, it may just need a fluid flush, but keep an ear out for persistent sounds.
Operate the climate control system through all settings, including the feet and windscreen vents. The blend door actuators are known to wear out, which can leave you stuck with one temperature on one side of the cabin. | Advice: Listen for clicking sounds behind the dash when switching modes, which suggests the actuator gears are struggling.
While on a rough piece of road, listen for clunks from the front suspension. The WK chassis puts a fair amount of stress on the front bushings and ball joints, which can wear over time in New Zealand conditions. | Advice: A quick visual check of the rubber boots for cracks or grease leaks during your inspection is always a good idea.
Usually the time to ensure the spark plugs have been refreshed and the cooling system has had a thorough check-over.
A common interval to check suspension components, including shocks and control arm bushings for signs of perishing.
Focus shifts to the longevity of the alternator and starter motor, which might start showing their age around this point.
Prioritise regular engine oil changes every 10,000km to keep the 3.7L PowerTech V6 internals clean.
Monitor the coolant condition regularly; fresh coolant helps protect the aluminium components in this engine.
Keep the differential fluids topped up and fresh, especially if you use the vehicle for towing or light off-roading.
Inspect the battery terminals for corrosion, as these vehicles can be sensitive to voltage drops which trigger false dashboard warning lights.
Ensure the air filter is kept clean to allow the 3.7L engine to breathe properly and maintain its best possible fuel efficiency.
Estimated repair costs if issues arise
Future Budget Planning: Over time, the rubber components in the suspension may perish. If you notice wandering or knocking on bumps, you might eventually need to budget for a front-end refresh.
Future Budget Planning: Depending on the car's history, the actuators controlling the heater airflow may require replacement. The cost covers the labour involved in accessing the dash area.
Future Budget Planning: Should the transmission start shifting firmly or holding gears, a technician might suggest servicing the valve body or solenoids to restore smooth operation.
