For this ute, coolant does more than just stop overheating. It raises the boiling point, lowers the freezing point, fights corrosion inside the alloy head and radiator, and helps prevent cavitation around the water pump. That protection keeps head gaskets happy, heater cores flowing, and radiators clear—key for long hauls, towing, and hot Aussie and Kiwi summers.

Most 2006 Hilux models were factory-filled with Toyota SLLC (pink), a pre-mixed 50/50 phosphate-OAT coolant. Technical service information sets long service life for SLLC: typically first replacement at around 160,000 km or up to 10 years, then about every 80,000 km or 5 years thereafter.
