Check the transmission during your test drive | Detail: While accelerating gently, observe if the 4-speed automatic shifts smoothly between gears. Hesitation or a 'flare' can be common in older V6 models, suggesting the fluid may be due for a professional flush.
Inspect the dashboard top for signs of heat damage | Detail: Check this by closely viewing the texture of the dash; the Windom is known for soft-touch plastics that, after years of NZ sun, can become sticky or develop hairline cracks.
Listen for ticking at cold start | Detail: While listening near the engine bay during a cold start, pay attention to any rhythmic ticking; the 1MZ-FE engine is very reliable, but timing components or valve clearances might require attention if neglected.
Test every window and sunroof switch | Detail: Check this by cycling every window up and down twice; the regulators in these cars can occasionally seize up if they haven't been used regularly, leading to slow or noisy operation.
Usually the time to confirm the second timing belt replacement has been performed.
A common point to check suspension bushings and struts for signs of fatigue.
An interval where alternator health and starter motor reliability should be monitored.
Ensure the engine oil is a high-quality synthetic blend to keep the V6 internals running cleanly.
Verify that the timing belt, tensioner, and water pump were replaced at the recommended intervals.
Check the coolant condition to prevent internal radiator corrosion, which is vital for the 3.0L V6 cooling system.
Keep the cabin air filter fresh to ensure the climate control system operates efficiently.
Regularly treat leather interiors with a quality conditioner to prevent cracking.
Estimated repair costs if issues arise
Because this V6 is an interference engine, it is wise to ensure the timing belt is fresh. If the service history is unclear, you might eventually need to budget for this preventative maintenance to ensure the engine remains reliable for years to come.
If you notice a clunking sound over speed bumps, it is common in cars of this age for the rubber bushings to show their wear. A full refresh of the control arm bushings can significantly improve the ride quality back to that signature 'Lexus-like' smooth experience.
Depending on how the car has been driven, you might eventually need to budget for a professional transmission fluid drain and fill. It is a proactive way to maintain smooth gear changes and prolong the life of the gearbox.
