Radiator: Testing and Inspection

2GR-FE COOLING: RADIATOR: ON-VEHICLE INSPECTION

ON-VEHICLE INSPECTION

1. CHECK RADIATOR CAP SUB-ASSEMBLY
(a) Measure the valve opening pressure.




(1) If there are water stains or foreign matter on rubber packings 1, 2 or 3, clean the part(s) with water and finger scouring.
(2) Check that rubber packings 1, 2 and 3 are not deformed, cracked or swollen.
(3) Check that 3 and 4 are not stuck together.
(4) Apply engine coolant to rubber packings 2 and 3 before using the radiator cap tester.




(5) When using the cap tester, tilt it to 30° or more above the horizontal.
(6) Pump the cap tester several times, and check the maximum pressure*.
Pump speed:
1 pump per second
*: Even if the cap cannot maintain the maximum pressure, it is not a defect.
Judgment Criterion:





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