COOLING SYSTEM


  1. OUTLINE


    1. The cooling system uses a pressurized forced circulation system with a pressurized radiator reserve tank assembly.

    2. The pressurized reservoir tank is used to prevent the engine coolant from deteriorating upon contact with external air.

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

    4. An aluminum radiator core is used for weight reduction.

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

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