3.0L 2JZ-GE I6 (163kW) - GS 300
Petrol
While performing low-speed maneuvers such as a U-turn or parking, listen closely for any clunking or popping sounds from the front end, as lower ball joints are a known consideration for this chassis.
Check this by cycling the central locking system several times using both the key fob and the internal switch to ensure all four door lock actuators engage and disengage reliably.
During your inspection of the engine bay, look specifically at the front of the 2JZ engine near the VVT-i gear for signs of oil weeping, which can occur as seals age in these powerplants.
While the car is parked, operate the tilt and telescopic steering wheel adjustment to ensure the electric motors move the column smoothly without grinding or getting stuck.
The 2JZ-GE engine typically requires a timing belt and water pump service at this interval; check for a sticker in the engine bay confirming this was completed.
At this stage, many owners consider refreshing the front suspension components and checking the condition of the radiator's plastic end tanks.
Depending on usage, this is a common time to inspect the alternator and oxygen sensors, as well as ensuring the transmission fluid has been regularly serviced.
With high-mileage examples, it is common to monitor the valve stem seals and rear main seal for any age-related weeping.
Confirm the presence of the 'Master Key' (with remote buttons), as programming new keys for this generation can be a more involved process.
Inspect the boot floor and around the tail lights for any signs of moisture, which can occasionally occur if the rubber seals have flattened over the years.
Verify the operation of the climate control LCD screen and the instrument cluster to ensure there is no 'bleeding' or loss of pixels in the digital displays.
Check the condition of the engine coolant; it should ideally be the Toyota-specific 'Long Life' pink or red fluid to protect the internal cooling passages.
Test the sound system specifically for clarity at higher volumes, as the surround foam on the factory Nakamichi or Lexus Premium speakers can degrade over two decades.
Estimated repair costs if issues arise
If the car's service history is unclear, it is wise to budget for this essential maintenance to ensure the 2JZ engine remains reliable for the long term.
In cars of this age, replacing the front lower ball joints is a common preventative measure to maintain the precise steering feel and safety the GS is known for.
Depending on the car's history, the original plastic radiator might eventually need attention if it shows signs of discoloration or hairline cracks due to heat cycles.
If a door fails to lock via the remote, you might eventually need to budget for a replacement motor unit, which is a common task for many Lexus models of this era.
