3.5L (2GR-FSE) - IS350 F-Sport/Luxury trim
Petrol
Gently accelerate and decelerate between 40-60km/h; notice if there is a 'flaring' or hesitation in gear shifts, as high-mileage A760E transmissions may eventually show signs of solenoid wear.
Turn the steering wheel to full lock in both directions while stationary and during slow maneuvers; listen for any clicking or clunking which may indicate the front control arm bushings are beginning to soften.
Check the infotainment and instrument cluster under direct sunlight; ensure the 'sticky dash' syndrome—common in this generation due to heat-sensitive surface materials—has not caused excessive melting or peeling.
Run the climate control on 'LO' and 'HI' for several minutes; ensure the servo motors for the blend doors operate smoothly without any rhythmic clicking sounds behind the dashboard.
Consider a full cooling system refresh including the water pump and thermostat, as these are known to be periodic service items for the 2GR-FSE engine.
The suspension components, specifically the lower control arm bushings and strut mounts, may be nearing the end of their optimal performance window.
Timing chain tensioner inspection is advised to ensure ongoing engine longevity and smooth idle performance.
Check the service history for regular engine oil changes using a high-quality full synthetic 5W-30 to protect the direct-injection system.
Inspect the condition of the serpentine belt and tensioner assembly for any signs of cracking or fraying.
Confirm the brake fluid has been flushed recently, as the IS350's electronic braking system relies on clean, moisture-free fluid.
Verify the condition of the intake manifold gaskets, as these can occasionally develop minor vacuum leaks over time.
Check for any signs of oil weeping around the timing cover or valve covers, which is helpful to catch early.
Estimated repair costs if issues arise
In cars of this age, the water pump can sometimes develop a weep. If this component needs attention in the future, the estimated cost in NZ includes replacing the pump, coolant, and potentially the thermostat to keep the 2GR-FSE running in its peak temperature range.
These bushings handle a lot of force and are a common wear item. Depending on the car's history, you might eventually need to budget for new bushings or upgraded polyurethane replacements to sharpen up the steering feel.
Because the 2GR-FSE uses direct injection, carbon buildup on the intake valves is something to consider. Planning for a professional walnut blasting or chemical cleaning can help maintain engine efficiency and throttle response.
