3.0L (2JZ-GE) - GS300
Petrol
Test drive task: Find a quiet road and listen for a 'clunk' over bumps. | Description: It is worth paying attention to the condition of the front lower ball joints and control arm bushings, as these components often show their age on second-generation GS models.
Test drive task: While cruising at a steady speed, observe the tachometer for any erratic needle movement. | Description: Keep an eye on the transmission's shifting quality; if it feels hesitant, consider that it might just need a fresh fluid flush, though it is wise to keep an eye on overall transmission health.
Check this by: Operating all electric features including the side mirrors and seat memory functions. | Description: The GS300 is feature-rich, so testing these small motors ensures they are still operational, as motors of this vintage can occasionally seize from lack of use.
Check this by: Looking under the vehicle and near the engine bay for any signs of weeping fluids. | Description: Checking the underside for minor oil leaks—particularly around the cam seals or the VVT solenoid—is a sensible way to gauge the maintenance history of the 2JZ engine.
Usually the time to inspect the cooling system, including radiator hoses and the water pump.
A good opportunity to review the condition of the alternator and starter motor.
Consider having a specialist inspect the suspension struts for any signs of weeping oil.
Keep a regular eye on the engine oil level every few fuel stops to ensure the 2JZ-GE remains happy.
Ensure the timing belt has been replaced according to the recommended service intervals.
Check the condition of the cabin air filter to keep the interior climate control system smelling fresh.
Schedule a professional brake fluid flush every two years to maintain that classic Lexus stopping power.
Keep the leather interior conditioned to ensure the seats remain supple and free from cracking.
Estimated repair costs if issues arise
Since the 2JZ-GE is an interference engine, it is vital to track when this was last changed. If the records are unclear, it is wise to budget for this job to ensure ongoing reliability.
Over many years in NZ conditions, rubber components can lose their elasticity. You might eventually need to budget for a suspension refresh to restore that trademark Lexus 'magic carpet' ride.
In cars of this age, the alternator is a component that may eventually require attention. If you notice the lights dimming or charging issues, this is something to factor into your future vehicle upkeep.
