СИСТЕМА ОХЛАЖДЕНИЯ


  1. OUTLINE


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

    2. An electric engine water pump assembly is used to reduce friction losses and weight.

    3. A thermostat 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. TOYOTA genuine Super Long Life Coolant (SLLC) is used.

  2. SPECIFICATION


    1. Engine Coolant


      1. TOYOTA genuine SLLC is used. The maintenance interval is as shown in the table below:

        Coolant Type TOYOTA Genuine SLLC or the Following*
        Maintenance Intervals First Time 160000 km (100000 miles)
        Subsequent Every 80000 km (50000 miles)
        Color Pink

        Tech Tips

        *: 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.)

      2. SLLC is pre-mixed (50 % coolant and 50 % deionized water), so no dilution is needed when adding or replacing SLLC.

    2. Thermostat

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