Система Охлаждения -- Проверка Без Снятия С Автомобиля


ПРЕДОСТЕРЕЖЕНИЕ:
Be sure that the ignition switch is off if you work near the electric cooling fans or radiator grille. With the ignition switch on, the electric cooling fans may automatically start to run if the engine coolant temperature becomes high and/or the air conditioning is turned on.


1. INSPECT FOR COOLANT LEAK
ПРЕДОСТЕРЕЖЕНИЕ:
To avoid the danger of being burned, do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.

  1. Fill the radiator assembly with engine coolant, then attach a radiator cap tester.

  1. Pump it to 108 kPa (1.1 kgf/cm2, 15.6 psi), then check that the pressure does not drop.
    If the pressure drops, check the hoses, radiator assembly and water pump assembly for leakage. If there are no signs or traces of external engine coolant leakage, check the heater core, cylinder block and head.



2. INSPECT RESERVOIR TANK ENGINE COOLANT LEVEL

  1. The engine coolant should be between the LOW and FULL lines when the engine is cold.

    УКАЗАНИЕ:
    If it is below the LOW line, check for leakage and add Toyota 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 up to the FULL line.


3. INSPECT ENGINE COOLANT QUALITY

  1. Remove the radiator cap sub-assembly.

    ПРЕДОСТЕРЕЖЕНИЕ:
    To avoid the danger of being burned, do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot.
    Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.

  1. Check for excessive deposits of rust or scale around the radiator cap sub-assembly and radiator filler hole. The engine coolant should be free of oil.
    If excessively dirty, replace the engine coolant.

  1. Reinstall the radiator cap sub-assembly.
