ON-VEHICLE INSPECTION
PROCEDURE
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 level. |
|
(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:
Item |
Specified Condition |
---|---|
Standard value (for brand-new cap) |
94 to 122 kPa (1.0 to 1.2 kgf/cm2, 13.6 to 17 psi) |
Minimum standard value (for used cap) |
79 kPa (0.8 kgf/cm2, 11.4 psi) |
If the measured maximum pressure is less than the minimum standard value, replace the radiator cap sub-assembly.
