Lexus UX 200/250h Water Pump Replacement Malaysia
UX 200 mechanical water pump: replace when leaking (typically 120,000–160,000 km) including coolant flush. UX 250h has an additional electric pump for the hybrid inverter circuit. Both pumps rarely fail before 150,000 km.

Lexus UX Water Pump
- UX 200 (M20A-FKS): belt-driven water pump — compact engine; inspect at 20,000 km; water pump on TNGA engine is accessible
- UX 250h: electric water pump for hybrid inverter circuit — separate from mechanical engine water pump; both need inspection at 100,000 km
- Water pump replacement on UX: TNGA platform — serpentine belt, tensioner, and water pump are often done together; cost-effective package
- UX coolant: Toyota SLLC — first change at 160,000 km; use distilled water for top-up between changes
