HINT:
-
Use of improper coolants may damage the engine cooling system.
-
Use only Toyota Super Long Life Coolant or similar high quality ethylene glycol based nonsilicate, nonamine, nonnitrite, and nonborate
coolant with long life hybrid organic acid technology (coolant with long life hybrid organic acid technology consists of a combination of
low phosphates and organic acids).
-
Toyota Super Long Life Coolant is premixed with 50% coolant and 50% deionized water. This coolant provides protection down to about
35°C (31°F).
d. Check the coolant level inside the radiator by pressing the inlet and outlet radiator hoses several times by hand. If the coolant level goes down,
add coolant.
e. Install the radiator cap securely.
f.
Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
g. Warm up the engine until the cooling fan operates.
1. Set the air conditioning as follows while warming up the engine.
2. Maintain the engine speed at 2,000 to 2,500 rpm and warm up the engine until the cooling fan operate.
h. Press the inlet and outlet radiator hoses several times by hand while warming up the engine.
i.
Stop the engine and wait until the coolant cools down.
j.
Remove the radiator cap and check the coolant level inside the radiator.
k. If the coolant level is below the full level, perform the steps from (a) through (b) and repeat the operation until the coolant level stays the full
level.
l.
Recheck the coolant level inside the radiator reservoir tank. If it is below the full level, add the coolant.
3. CHECK FOR ENGINE COOLANT LEAKAGE
a. Fill the radiator with engine coolant and attach a radiator cap tester.
b. Pump it to 118 kPa (1.2 kgf/cm2, 17.1 psi) and check for leakage.
