ON-VEHICLE INSPECTION

CAUTION / NOTICE / HINT

CAUTION:

Do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

PROCEDURE

1. INSPECT FOR COOLANT LEAK

CAUTION:

Do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

(a) Remove the radiator cap sub-assembly.

(b) Fill the radiator assembly with engine coolant, and then install a radiator cap tester.

*a

Radiator Cap Tester

(c) Warm up the engine.

(d) Pump the radiator cap tester to 103 kPa (1.1 kgf/cm2, 15 psi), and then check that the pressure does not drop.

  • If the pressure drops, check the hoses, radiator assembly and engine water pump assembly (water inlet housing) for leaks.
  • If there are no signs of external engine coolant leaks, check the heater core, cylinder block sub-assembly and cylinder head sub-assembly.

(e) Remove the radiator cap tester.

(f) Install the radiator cap sub-assembly.

2. INSPECT ENGINE COOLANT LEVEL IN RESERVOIR TANK

(a) Check that the engine coolant level is between the L line and F line when the engine is cold.

If the engine coolant level is low, check for leaks and add engine coolant to the F line.

NOTICE:

Do not substitute plain water for engine coolant.

F Line

*b

L Line

3. INSPECT ENGINE COOLANT QUALITY

CAUTION:

Do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

(a) Remove the radiator cap sub-assembly.

(b) Check if there are any excessive deposits of rust or scale around the radiator cap sub-assembly and water filler hole. Also, the engine coolant should be free of oil.

If excessively dirty, replace the engine coolant.

(c) Install the radiator cap sub-assembly.
