COOLING SYSTEM


  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 aluminum radiator core is used for weight reduction.

    4. A water-cooled type engine oil cooler is used.

    5. Toyota Genuine Super Long Life Coolant (SLLC) is used.

    6. On the models compliant with EURO 4 emission regulations, a water-cooled type EGR cooler that is integrated with a bypass is used.
