Lexus RX 270/350/450h Coolant Flush & Replacement Malaysia
Use Toyota SLLC (pink) for all RX variants; flush every 40,000 km or 2 years. The RX 450h adds a separate inverter coolant circuit (blue Toyota Genuine), renewed at 100,000 km or 10 years. V6 models (RX 350/450h) have higher coolant capacity — a full flush uses more coolant than 4-cylinder variants.
