3.5L 6VE1 V6 - Base/LX trim
Petrol
While driving, steer into a quiet area and engage the 4WD system; ensure the 'Shift-on-the-fly' mechanism engages smoothly without clunking or flashing dashboard lights.
With the engine at operating temperature, observe the exhaust; blue or grey smoke can suggest that valve stem seals or piston rings might require investigation as these V6 engines age.
During slow speed maneuvers, listen closely for any clicking or popping sounds from the front end, as CV joints on these robust SUVs often require attention after high mileage.
Carefully monitor the temperature gauge during a longer test drive; these cooling systems are generally reliable, but any fluctuations could indicate the radiator or cooling fan clutch is nearing the end of its service life.
Consider a full cooling system refresh including the water pump, which is often done alongside the timing belt.
Expect the suspension bushings and shock absorbers to show signs of wear; refreshing these will significantly improve the ride quality.
Check the condition of the alternator and starter motor, as they may eventually need professional servicing or replacement.
Regularly check the engine oil levels, as keeping the 6VE1 engine well-lubricated is essential for longevity.
Ensure the transmission fluid is clean and clear to keep the automatic gearbox shifting smoothly.
Keep an eye on the timing belt interval; it is a critical maintenance item for this engine and peace of mind is worth the investment.
Inspect the undercarriage for any surface rust, especially if the vehicle has spent time near the coast.
Test all electrical accessories, including the power windows and central locking, as aged wiring can sometimes be a bit temperamental.
Estimated repair costs if issues arise
Since this is an interference engine, you might eventually need to budget for this replacement to ensure the long-term health of the valvetrain.
If this component needs attention in the future, the estimated cost in NZ covers replacing worn rubber components to restore that stable Monterey handling.
Depending on the car's history, you might eventually need to budget for a new radiator or hoses to keep the 3.5L V6 running at the right temperature.
