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 rubber packings 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. *1
Pumping speed:
1 pump every second
*1: Even if the cap cannot maintain the maximum pressure, it is not a defect.
Judgment Criteria:






If the maximum pressure is less than the specified pressure for the minimum standard valve, replace the radiator cap sub-assembly.
