Coolant: Testing and Inspection
COOLANTON-VEHICLE INSPECTION
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.
1. DRAIN ENGINE COOLANT
a) Loosen the radiator drain plug.
b) Remove the radiator cap and drain the coolant.
c) Loosen the cylinder block drain cock.
HINT: Dispose of the coolant according to the regulations in your area.
2. ADD ENGINE COOLANT
a) Tighten all the plugs and fill the radiator with TOYOTA Super Long Life Coolant (SLLC).
Torque: 13 Nm (129 kgf-cm, 9.4 ft. lbs.)
Standard capacity
Standard capacity:
b) Fill the radiator reservoir with TOYOTA Super Long Life Coolant (SLLC) to the full line.
HINT:
^ The use of improper coolant may damage the engine cooling system.
^ Only use TOYOTA Super Long Life Coolant or similar high quality ethylene glycol based nonsilicate, non-amine, non-nitrite, and non-borate 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).
^ New TOYOTA vehicles are filled with TOYOTA Super Long Life Coolant (color is pink, premixed ethylene glycol; concentration is approximately 50%; and freezing temperature is -35°C (-31°F)). When replacing the coolant, TOYOTA Super Long Life Coolant is recommended.
NOTICE: Never use water as a substitute for engine coolant.
c) 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.
d) Install the radiator cap securely.
e) Slowly pour coolant into the radiator reservoir until it reaches the full line.
f) 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 operates.
g) Press the inlet and outlet radiator hoses several times by hand while warming up the engine.
NOTICE: When pressing the radiator hoses:
^ Wear protective gloves.
^ Be careful as the radiator hoses are hot.
^ Keep your hands away from the radiator fan.
h) Stop the engine and wait until the coolant cools down.
i) Remove the radiator cap and check the coolant level inside the radiator.
j) Check the coolant level in the radiator reservoir.
If the coolant level is low, add SLLC to the reservoir full line.
3. CHECK FOR ENGINE COOLANT LEAKS
a) Fill the radiator with engine coolant and attach a radiator cap tester.
b) Pump the tester to 137 kPa (1.4 kgf/cm2, 19.9 psi) and check for leakage.
