Lexus GX 460 Water Pump
- GX 460 (1GR-FE): belt-driven water pump — inspect at 100,000 km; 1GR-FE water pump is robust but not immortal
- Water pump on 1GR-FE: relatively easy access vs V8 engines — labour cost is lower than LX/LS; replace proactively at 150,000 km
- Coolant system: V6 has simpler cooling system than hybrids — single coolant circuit; Toyota SLLC at 160,000 km then 80,000 km
- Off-road water pump stress: heavy 4WD use — water pump works harder than city-only vehicles; inspect more frequently if used off-road
