You will need: coolant, clean rag, 10-liter container for draining coolant, TORX T70 socket wrench.
WARNING: Use ethylene glycol based coolants (antifreeze).
WARNING: Change the coolant only when the engine is cold.
WARNING: Coolant is toxic so be careful when handling it.
WARNING: When starting the engine, the expansion tank cap must be closed. Screw the tank cap tightly. The cooling system is pressurized when the engine is running, so coolant may leak from under the loose cap.
1. Install the car on a flat horizontal platform.
2. Turn away a stopper of a broad tank.
3. Place a container under the drain plug..
4.... and, having unscrewed the plug, drain the coolant.
WARNING: Antifreeze is deadly poisonous to all living things. In order not to pollute the environment, drain it from the radiator through a funnel (for example, made from a plastic soda bottle).
NOTE: If the expansion tank is heavily soiled, remove (see Removing and installing expansion tank) and wash it.
5. Flush the cooling system by screwing in the drain plug and filling the system with water through the expansion tank.
6. Start the engine and let it run until the electric fan turns on.
7. Stop the engine and drain the water.
8. Flush the cooling system until clean water begins to drain.
9. Replace the drain plug.
10. Fill the engine cooling system by pouring coolant into the expansion tank.
11. Start the engine and warm it up to operating temperature (before turning on the electric fan). After that, stop the engine, check the coolant level and, if necessary, add it to the expansion tank up to the "MAX" mark.
NOTE: When the engine is running, watch the coolant temperature on the gauge. If the arrow has reached the red zone, and the radiator 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 and unscrew the plug of the expansion tank. Start the engine, let it run for 3-5 minutes and tighten the reservoir cap.
USEFUL ADVICE: To better fill the system without air pockets, periodically squeeze the radiator hoses with your hand.
USEFUL ADVICE: After a few days of operation of the car after replacing the coolant, check its level. Top up if necessary.
USEFUL ADVICE: If after a very short time the color of the fresh liquid turns brown, then you have filled in a fake, in which the manufacturer "forgot" to add corrosion inhibitors. In addition, one of the signs of a fake is a sharp complete discoloration of the liquid. The dye of a good coolant is very resistant and only darkens over time. The liquid, tinted with linen blue, is discolored. Such "antifreeze" must be replaced faster.
