  1. OUTLINE

    1. The cooling system is a pressurized, forced-circulation type.

    2. A thermostat with a bypass valve is located on the water inlet housing to maintain suitable temperature distribution in the cooling system.

    3. An aluminium radiator core is used for weight reduction.

    4. The flow of the engine coolant makes a U-turn in the cylinder block to ensure a smooth flow of the engine coolant. In addition, a bypass passage is enclosed in the cylinder head and the cylinder block.

    5. Warm water from the engine is sent to the throttle body to prevent freeze-up.

  2. SPECIFICATION

    1. Engine Coolant

      1. Toyota genuine Super Long Life Coolant (SLLC) is used. Maintenance interval is as shown in the table below:

        Engine Coolant Type SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids). Do not use plain water alone.
        Maintenance Intervals First time 160000 km (100000 miles)
        Subsequent Every 80000 km (50000 miles)
        Color Pink

        Tech Tips

        SLLC is pre-mixed (50% coolant and 50% deionized water). Therefore, no dilution is needed when SLLC in the vehicle is added or replaced.

    2. Thermostat

      Thermostat Opening Temperature 80°C to 84°C (176°F to 183°F)
