- INSPECT RESERVE TANK CAP
- Measure the valve opening pressure.
*a O-ring *b Rubber Packing - If there are water stains or foreign matter on the O-ring, clean it with water and finger scouring.
- Check that the O-ring is not deformed, cracked or swollen.
- Apply engine coolant to the O-ring and rubber packing before using a radiator cap tester.
- When using the radiator cap tester, tilt it upwards 30° or more.
*1 Reserve Tank Cap *a Radiator Cap Tester *b 30° or more - Pump the radiator cap tester several times, and check the maximum pressure.
Pump Speed

HINT:
Even if the reserve tank cap cannot maintain the maximum pressure, it is not a defect.
Result
Item Specified Condition Standard pressure
(for brand-new reserve tank cap)93 to 123 kPa (1.0 to 1.3 kgf/cm2 , 13.5 to 18.0 psi) Minimum pressure
(for used reserve tank cap)79 kPa (0.8 kgf/cm2 , 11.5 psi) If the maximum pressure is less than the minimum pressure, replace the reserve tank cap.
- Measure the valve opening pressure.
