4.3L (3UZ-FE) V8 - C-Type/F-Package Luxury
Petrol
Gently accelerate and decelerate at low speeds to observe if the 5-speed or 6-speed transmission exhibits any hesitation, as high-mileage units can occasionally develop minor solenoid wear.
Navigate over speed bumps and uneven tarmac specifically to listen for any knocking sounds from the front lower control arm bushings, a common consideration for vehicles of this age and weight.
Park the vehicle on a level surface after a drive and check the underside near the front struts; while the air suspension is incredibly comfortable, it is worth monitoring for any signs of slow leaks or compressor fatigue.
Spend time testing the 'soft-close' door and trunk mechanisms; these convenience features are complex, and it is common for the motors to eventually require a reset or minor electrical maintenance.
Typically the time for a major timing belt and water pump service if not already documented.
Often when suspension components like bushings and potentially air strut bladders may start showing their age.
Consider a full cooling system refresh, including radiator and hoses, to ensure the 3UZ-FE engine remains in its reliable prime.
Verify the timing belt replacement history, as the 3UZ-FE is an interference engine that relies on this service being up to date.
Check all electronic seat and steering column adjustments, as these utilize multiple motors that enjoy regular movement to stay lubricated.
Inspect the condition of the under-bonnet plastics and rubber hoses, as these can become brittle after decades of heat cycles.
Ensure the navigation and infotainment system is functioning; if it's the original Japan-spec unit, be mindful that it may have limited functionality in New Zealand.
Check that the power steering reservoir fluid is clean, as the pump is known for being sensitive to old or contaminated oil.
Estimated repair costs if issues arise
If the vehicle begins to sag overnight, it is common to consider replacing the air struts. While they offer a legendary ride, they are a wearable item.
To keep your V8 running smoothly, this is a vital preventative maintenance task to schedule every 100,000km.
If you notice a slight wander in steering or noise over bumps, these bushings may eventually need replacing to restore that 'vault-like' feel.
