1. CHECK RADIATOR RESERVOIR CAP SUBASSEMBLY

(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*.
Pump speed: 1 pump per second
*: Even if the cap cannot maintain the maximum pressure, it is not a defect.
