  1. Measure the valve opening pressure.

Toyota RAV4. Check radiator reservoir cap subassembly


  1. If there are water stains or foreign matter on oring 1, clean it with water and finger scouring.
  2. Check that o-ring 1 is not deformed, cracked or swollen.
  3. Apply engine coolant to o-ring 1 and rubber packing 2 before using a radiator cap tester.
  4. When using the cap tester, tilt it more than 30 degrees.
  5. 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 maximum pressure is less than the minimum standard value, replace the radiator reservoir cap sub-assembly.

On-vehicle cleaning
