The engine coolant must be changed for the first time after 160,000 km of the vehicle.
Subsequently, replace every 80,000 km of the car
Selecting the type of coolant
The use of inappropriate coolants can damage the engine cooling system.
Be sure to use "Toyota Super Long Life Coolant" or an equivalent high quality, silicate, amine, nitrite, and borate-free ethylene glycol type coolant 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).
Toyota Super Long Life Coolant is a mixture containing 50% coolant and 50% deionized water.
This coolant provides protection down to -35°C.
We install the car on a lift or a viewing ditch
Remove the lower mudguards of the engine
Turn counterclockwise and remove the radiator cap
Open the plug of the expansion tank without disconnecting the steam outlet hose from it
We substitute the container under the drain valve of the radiator of the cooling system located in the lower tank of the radiator
Unscrew the drain valve plug by 2-3 turns and drain the liquid
After that, we substitute the container under the drain valve of the cooling system located on the left side of the cylinder block
Unscrew the drain valve plug by 2-3 turns and drain the liquid
Tighten the plugs of both drain valves by hand
If the expansion tank is very dirty, then remove it and rinse it with water
We flush the cooling system, for this we fill the system with water through the filler neck to the level of the steam outlet pipe
Start the engine and let it run until the electric fan is turned on
Turn off the engine and drain the water
Flush the cooling system until clean water starts to drain
After that, we fill the engine cooling system by slowly pouring coolant into the radiator to the level of the vapor pipe
Start the engine and warm it up to operating temperature (before turning on the fan).
As air escapes from the system, add coolant to the radiator.
The fan will turn on 3-5 times until the air is completely exhausted
We twist the radiator cap and add coolant to the expansion tank to the "F" mark.
After that, stop the engine and let it cool down
Check the coolant level and, if necessary, add it to the expansion tank to the "F" mark.
When the engine is running, you need to monitor the temperature of the coolant according to the pointer
If the arrow reaches the red zone, and the fan does not turn on, turn on the heater and check how much air passes through it.
If the heater supplies heated air, the fan is most likely defective, and if it supplies cold air, then an air lock has formed in the engine cooling system.
To remove it, turn off the engine, let it cool down, and unscrew the radiator cap.
Start the engine, let it run for 3-5 minutes, and tighten the radiator cap
To better fill the system without air pockets, periodically squeeze the radiator hoses with your hand
After a few days of car operation after replacing the coolant, we control its level and color of the liquid.
If after a very short time the color of the fresh liquid turned brown, then you filled in a fake, in which the manufacturer did not add corrosion inhibitors
In addition, one of the signs of a fake is a sharp complete discoloration of the liquid. The liquid tinted with linen blue is discolored.
