NOTICE:
Do not substitute plain water for engine coolant.
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 is a combination of low phosphates and organic acids).
(b) Press the No. 1 radiator hose and No. 2 radiator hose several times by hand, and then check the engine coolant level. If the engine coolant level is low, add engine coolant.
(c) Remove the reserve tank cap sub-assembly.
(d) Slowly pour engine coolant into the radiator reservoir tank until it reaches the FULL line.
(e) Install the reserve tank cap sub-assembly.
(f) Bleed air from the cooling system.
(1) Warm up the engine until the thermostat opens. While the thermostat is open, circulate the engine coolant for several minutes.
NOTICE:
HINT:
The thermostat open timing can be confirmed by pressing the No. 2 radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.
(2) Maintain the engine speed at 2000 to 2500 rpm.
(3) Press the No. 1 radiator hose and No. 2 radiator hose several times by hand to bleed air.
(g) Stop the engine, and wait until the engine coolant cools down to ambient temperature.
(h) Check the engine coolant level in the radiator reservoir tank.
If the engine coolant level is low, add engine coolant to the radiator reservoir tank FULL line.
5. INSPECT FOR COOLANT LEAK
6. INSTALL NO. 1 ENGINE UNDER COVER SUB-ASSEMBLY
Torque:
30 N·m {306 kgf·cm, 22 ft·lbf}
7. INSTALL NO. 2 ENGINE UNDER COVER SUB-ASSEMBLY (w/ Off Road Package)
Torque:
