COOLING SYSTEM


  1. OUTLINE


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

    2. A small double-row ball bearing is used, achieving reduced size as well as ensuring reliability.

    3. A stainless steel rotor with superior corrosion resistance is used to ensure reliability.

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

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

  2. SPECIFICATION


    1. Engine Coolant

      Type Toyota Genuine Super Long Life Coolant (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.
      Color Pink
      Maintenance Intervals First Time 160000 km (100000 miles)
