(b) Tighten the 2 cylinder block drain cock plugs.

Torque: 13 Nm (133 kgf-cm, 10 ft-lbf)

(c) Add TOYOTA Super Long Life Coolant (SLLC) into the radiator reservoir.

Capacity:
Approximately 5.0 liters (5.3 US qts, 4.4 Imp. qts)

HINT:
-

TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other
technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, 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).

-

Contact any authorized TOYOTA dealer or repairer or another duly qualified and equipped professional for further details.

-

Thermostat opening timing can be confirmed by squeezing the inlet radiator hose and sensing vibrations when the coolant starts to flow
inside the hose.

(d) Further add coolant into the reservoir until it reaches the FULL line.
(e) Squeeze the No. 1 and No. 2 radiator hoses several times, and then check the coolant level.

If the coolant level is low, add coolant.

(f) Using a 6 mm hexagon wrench, install the vent plug.

Torque: 1.5 Nm (15 kgf-cm, 13 in-lbf)

(g) Bleed air from the cooling system.

NOTICE:

Before starting the engine, turn the A/C switch OFF.

(1) While idling the engine for approximately 10 minutes, make sure that the coolant remains at the FULL line by adding coolant as necessary.

(2) After idling the engine for 10 minutes, add coolant to the level shown in the illustration.

Capacity:
Approximately 2.5 to 3.5 liters (2.6 to 3.7 US qts, 2.2 to 3.1 Imp. qts)

(3) Close the radiator reservoir cap, and run the engine at 1500 to 2000 rpm for 5 minutes.
HINT:

Thermostat opening timing can be confirmed by squeezing the No. 1 radiator hose and sensing vibrations when the SLLC starts to flow inside the hose.

CAUTION:

When squeezing the radiator hoses:

Pinch or Ctrl + scroll to zoom. Double-tap to reset.
