Радиатор Проверка Без Снятия С Автомобиля. Corolla Auris

Measure the valve opening pressure.

1. If there are water stains or foreign matter on O-ring 1, clean it with water and finger scouring.
   

2. Check that O-ring 1 is not deformed, cracked or swollen.
   

3. Apply engine coolant to O-ring 1 and rubber packing 2 before using a radiator cap tester.
   





4. When using the cap tester, tilt it more than 30°.
   

5. Pump the cap tester several times, and check the maximum pressure*.
   

   Pump speed:

   1 pump per second
   

   УКАЗАНИЕ:

   *: Even if the cap cannot maintain the maximum pressure, it is not a defect.

   Judgment criterion:

   Item	Specified Condition
   Standard value (for brand-new cap)	93.3 to 122.7 kPa (0.95 to 1.25 kgf/cm2, 13.5 to 17.8 psi)
   Minimum standard value (for used cap)	78.5 kPa (0.8 kgf/cm2, 11.4 psi)

   If the maximum pressure is less than the minimum standard value, replace the radiator reservoir cap sub-assembly.
   

Check that the radiator, condenser and intercooler are not blocked with leaves, dirt, or insects. Clean the hose connections.
If the fins are blocked, wash them with water or a steam cleaner.

ПРИМЕЧАНИЕ:

1. If the distance between the steam cleaner and core is too close, the fins may be damaged.
   
2. When cleaning the intercooler, make sure no water enters its interior.
   
3. Keep the following injection distance.
   

   Standard injection distance:

   Injection Pressure	Specified Condition
   2942 to 4903 kPa (30 to 50 kgf/cm2, 427 to 711 psi)	300 mm (11.81 in.)
   4903 to 7845 kPa (50 to 80 kgf/cm2, 711 to 1.138 psi)	500 mm (19.69 in.)

4. If the fins are bent, straighten them with a screwdriver or pliers.
   
5. Never apply water directly onto the electronic components.
   

Dry the fins with compressed air.
