5.7L (3UR-FE) V8 - Modern Luxury Flagship
Petrol
Check this by shifting through the transmission gears while stopped on a slight incline; ensure there is no hesitation or clunking as the 8-speed automatic engages, as these gearboxes benefit from regular fluid changes.
While driving at motorway speeds, monitor the suspension ride height adjustment; ensure the vehicle levels out properly and that there are no warning lights on the dash indicating issues with the AHC (Active Height Control) system.
During your walk-around, inspect the upper control arm bushings and steering rack boots; in heavier vehicles like the LX570, these components often experience wear that might present as minor vibrations over time.
Test this by cycling through the infotainment and navigation touch interface; ensure the screen responsiveness is consistent, as the internal hardware in vehicles of this age can occasionally require a reset or component service.
Consider a full drivetrain fluid service including the transfer case and both differentials to ensure long-term smoothness.
A common point to have the AHC suspension fluid checked and flushed to maintain ride comfort.
Evaluate the condition of the radiator and coolant hoses, as the cooling system has performed a lot of work in a V8 of this size.
Verify the 'coolant valley' area for any signs of historical leakage, a minor but known quirk of these engines.
Check that the 4WD selector functions smoothly and engages all modes without excessive noise.
Confirm the air conditioning system is blowing cold across all three zones, as the LX570 has a complex climate control layout.
Ensure the 3UR-FE V8 has a comprehensive service history, ideally with oil changes every 10,000km.
Check the brake pads and rotors, as the sheer mass of the vehicle means they are wear-and-tear items that require regular monitoring.
Estimated repair costs if issues arise
The AHC system uses specific hydraulic fluid and spheres to manage ride height. If the ride feels harsh or the vehicle is slow to lift, you might eventually need to budget for a system flush or sphere replacement.
Given the heat generated by the 5.7L V8, it is wise to plan for a cooling system overhaul if the service history is unclear. This includes the water pump, thermostat, and coolant flush.
As the vehicle reaches higher mileage, the rubber components in the suspension may begin to show their age, which can affect steering precision. Budgeting for a professional alignment and bushing inspection is recommended.
