Measure the valve opening pressure.

i.

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


ii.

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


iii.

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

v.

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

Pump Speed:

Result:
Item Specified Condition
Standard pressure
(for brand-new reserve tank cap (for Intercooler)) 		93 to 123 kPa (0.9 to 1.3 kgf/cm2, 13.5 to 18.0 psi)
Minimum pressure
(for used reserve tank cap (for Intercooler)) 		79 kPa (0.8 kgf/cm2, 11.5 psi)


HINT:

Even if the reserve tank cap (for Intercooler) cannot maintain the maximum pressure, it is not a defect.


If the maximum pressure is less than the minimum pressure, replace the reserve tank cap (for Intercooler).
