ON-VEHICLE INSPECTION

1. INSPECT FOR COOLANT LEAK

a. Fill the radiator with coolant and attach a radiator cap tester.

b. Warm up the engine.

c. Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm

2

, 17

psi), and check that the pressure does not drop. If the pressure drops, check the hoses, radiator and
water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.

2. CHECK ENGINE COOLANT LEVEL IN RESERVOIR

a. Check that the engine coolant level is between the LOW and FULL lines when the engine is cold.

If the engine coolant is low, check for leaks and add "TOYOTA Super Long Life Coolant" or
similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite and non-borate
coolant with long-life hybrid organic acid technology to the FULL line.

CAUTION: Do not remove the radiator cap while the engine and radiator are still

hot. Pressurized, hot engine coolant and steam may be released and
cause serious burns.

NOTE:

Do not substitute plain water for engine coolant.
