1. DRAIN COOLANT (for Engine) NOTE: Do not remove the reserve tank cap and radiator drain cock plug while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns. Loosen the radiator drain cock plug. Remove the reserve tank cap and drain the coolant. TEXT IN ILLUSTRATION *1 Reserve Tank Cap *2 Radiator Drain Cock Plug HINT: Collect the coolant in a container and dispose of it according to the local regulations.
2. ADD COOLANT (for Engine) Tighten the radiator drain cock plug. Remove the reserve tank cap. Add coolant up to the B line of the reserve tank. TEXT IN ILLUSTRATION *1 B Line Standard Capacity Item Capacity Engine coolant 6.9 liters (7.3 US qts, 6.1 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). NOTE: Never use water as a substitute for engine coolant. 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. Install the reserve tank cap. Put the engine in inspection mode. Refer to «INSPECTION MODE PROCEDURE»(/toyota/prius-v/i-2011-2014/remont/hoistjack/#introduction) . 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. 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 the full and low lines. TEXT IN ILLUSTRATION *1 Full Line *2 Low Line If the coolant level is low, add coolant up to the full line on the reserve tank.
