4. ADD COOLANT (for Engine) Tighten the radiator drain cock plug. Tighten the cylinder block drain cock plug. Torque: 13 N*m (130 kgf*cm, 9 ft.*lbf) Remove the reservoir tank cap. Connect the hose to the air release valve. Loosen the air release valve. Add TOYOTA Super Long Life Coolant (SLLC) to the reservoir tank filler opening until coolant overflows from the air release valve. Then tighten the air release valve. Standard Capacity Item Capacity Engine coolant w/ Exhaust Heat Recirculation System: 7.3 liters (7.7 US qts, 6.4 lmp. qts) w/o Exhaust Heat Recirculation System: 6.5 liters (6.8 US qts, 5.7 lmp. 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 is a combination of low phosphates and organic acids). Contact your TOYOTA dealer for further details. NOTE: Never use water as a substitute for engine coolant. Disconnect the hose from the air release valve. Add coolant to B line of the reservoir tank. TEXT IN ILLUSTRATION *1 B Line Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant. If the coolant level is low, add coolant. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(/toyota/prius-phv/pre-iii-2010-2011/remont/hoistjack/#introduction-except-phv) . Install the reservoir tank cap, and warm up the engine sufficiently. Bleed air from the cooling system. NOTE: Before starting the engine, turn the A/C switch off. Adjust the heater control to the maximum hot setting. Adjust the blower speed to low setting. Warm up the engine until the thermostat opens. While the thermostat is open, allow the coolant to circulate for several minutes. HINT: The thermostat opening timing can be confirmed by squeezing the inlet radiator hose by hand, and sensing vibrations when the engine coolant starts to flow inside the hose. WARNING: When squeezing the radiator hose: Wear protective gloves. Be careful as the radiator hoses are hot. Keep your hands away from the radiator fan. After the engine is warmed up, let it idle for 7 minutes or more. Squeeze the inlet and outlet radiator hoses several times by hand to bleed air from the system. WARNING: When squeezing the radiator hose: Wear protective gloves. Be careful as the radiator hoses are hot. Keep your hands away from the radiator fan. After the engine has cooled down, check that the coolant level is between full and low. TEXT IN ILLUSTRATION *1 Full Line *2 Low Line If the coolant level is low, add coolant to the full line on the reservoir tank.
