3.6L V6 (Alloytec) - Base trim
Petrol
Check this by observing the dash display for pixel fading or error codes, as the electronic control modules in the Statesman WL are starting to show their age in our NZ climate.
Perform a few gear changes in 'Sport' mode; note any harshness or 'flaring' between shifts, as the 5L40-E transmission may eventually require professional diagnostic attention if it hasn't been serviced regularly.
Check this by inspecting the oil filler cap for milky residue, as the Alloytec V6 engines can occasionally show signs of cooling system wear that may affect long-term reliability.
While driving at low speeds, gently turn the wheel lock-to-lock to feel for any binding or clicking, as the power steering pumps on the WL generation are known to be sensitive to fluid degradation over time.
Usually marks the point where cooling system hoses and the water pump may start showing signs of fatigue.
Consider a full transmission service and fluid flush if not recently documented, as this helps maintain smooth shifting.
Often the time when suspension bushings, particularly the rear subframe mounts, might require a refresh to maintain that famous Statesman ride quality.
Keep a consistent eye on the coolant levels; these Alloytec engines appreciate a healthy cooling system.
Ensure the transmission fluid remains a healthy reddish-pink color to keep the gearbox happy.
Stick to high-quality engine oil and change it every 10,000km to manage the timing chain health.
Regularly clean the drain holes around the sunroof and body panels to prevent moisture buildup in our damp NZ winters.
Check the rear differential fluid periodically, especially if you intend to use the vehicle for long-distance highway cruising.
Estimated repair costs if issues arise
Future Budget Planning: These engines utilize timing chains that can stretch over high mileage. If the car starts to throw specific cam-timing codes, it is wise to consult a specialist.
Future Budget Planning: Depending on the car's history, you might eventually need to budget for a transmission service or torque converter repair if shifting becomes less than smooth.
Future Budget Planning: If this component needs attention in the future—specifically the control arm bushes or struts—the estimated cost in NZ covers parts and professional alignment to restore that luxury comfort.
