INTRODUCTION:

The procedure for inspecting the radiator cap has been revised. Please refer to the following procedures when inspecting the radiator cap on all

Lexus models.

APPLICABLE VEHICLES:

2010 Lexus Truck RX 350 AWD V6-3.5L (2GR-FE) Page 193

- All Lexus model vehicles.

REQUIRED EQUIPMENT:

WARRANTY INFORMATION:

REQUIRED SSTs:

RADIATOR IDENTIFICATION PROCEDURE:

1. Use the illustration below to identify the vehicle's radiator cap type and kPa rating.

2. Proceed to the required inspection procedure for the radiator cap and kPa rating.

RADIATOR CAP INSPECTION PROCEDURE:

2010 Lexus Truck RX 350 AWD V6-3.5L (2GR-FE) Page 194

Type: N-cap, 88 kPa

1. Remove coolant and any foreign material on rubber points "A," "B," and "C."

2. Check that points "A," "B," and "C" are not deformed, cracked, or swollen.

3. Check that points "C" and "D" are not stuck together.

4. Apply engine coolant to points "B" and "C" before using the radiator cap tester.

Radiator Cap Tester:

5. Before installing the radiator cap tester, use the applicable radiator cap adaptor provided in the following SST kits in conjunction with the

radiator cap tester:

- SST P/N 09230-00030-01, 09230-00020-01, 09230-00050-01

6. When using the radiator cap tester, tilt it more than 30 degrees.

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

Pumping speed: 1 pump/second

HINT:

Stop pumping when the valve opens and read the gauge. The gauge must be within the standard values listed below when the pressure valve

opens. The cap is considered OK when the pressure holds steady or falls very slowly, but holds within the standard values listed below for

one minute.

Specification:

If the maximum pressure is less than the minimum standard value, replace the radiator cap sub-assembly.

Type: N-cap, 108 kPa

1. Remove coolant and any foreign material on rubber points "A," "B," and "C."

2. Check that points "A," "B," and "C" are not deformed, cracked, or swollen.

3. Check that points "C" and "D" are not stuck together.

4. Apply engine coolant to points "B" and "C" before using the radiator cap tester.
