The coolant level in the reservoir varies with engine temperature. But if the level is on the line «L» or lower, add coolant. Level up to the line «F».
If the coolant level drops in a short time after topping up, there may be a leak in the system. Visually inspect the radiator, hoses, coolant filler cap, radiator cap, drain cock and water pump.
Selecting the type of coolant
The use of inappropriate coolants can damage the engine cooling system.
Be sure to use coolant «Toyota Super Long Life Coolant (Toyota Ultra Long Life Coolant)» or equivalent high quality, silicate, amine, nitrite and borate free ethylene glycol type fluid formulated with long life hybrid organic acid technology (long life hybrid organic acid coolant is a combination of organic acids with a low phosphate content).
Coolant «Toyota Super Long Life Coolant (Toyota Ultra Long Life Coolant)» is a mixture containing 50% coolant and 50% deionized water. This coolant provides protection down to temperatures around -35°C.
