Toyota Sienna Service Manual: On-vehicle inspection
1. CHECK RADIATOR RESERVOIR CAP SUBASSEMBLY
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 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.
Judgment criterion
If the maximum pressure is less than the minimum standard value, replace the radiator reservoir cap sub-assembly.
