According to the manufacturer's recommendation, the coolant should be replaced after 45 thousand km of mileage or 2 years of operation (whichever comes first).
WARNINGS: Use ethylene glycol based coolants (antifreeze).
Replace coolant only when the engine is cold.
When starting the engine, the expansion tank cap must be closed. Screw the tank cap tightly. The cooling system is under pressure when the engine is running, so coolant may leak from under a poorly screwed cap.
Coolant is toxic, so be careful when handling it.
1. Place the vehicle on a lift or inspection pit.
2. Remove the front engine splash guard (see "Removal and installation mudguards and engine crankcase protection").
3. Unscrew the expansion tank cap.
4. Place a container under the drain cock on the radiator of the cooling system, located at the bottom of the tank on the right side of the radiator.
5. Turn off the tap...
6. ...and drain the liquid.
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 bottle). If you don't have a hose of the appropriate diameter, you can use, for example, a cut-off canister.
7. To ensure complete drainage of the fluid from the system and guaranteed removal of air from it when filling, squeeze the tabs of the clamp securing the throttle heating hose, slide the clamp along the hose and remove the hose from the throttle assembly fitting.
8. Close the drain valve.
NOTE: If the expansion tank is heavily contaminated, remove (see "Removal and installation the expansion tank") and rinse it.
9. Flush the cooling system by reinstalling the coolant supply hose to the throttle assembly and slowly filling the system with water through the expansion tank to the level of the steam outlet tube.
10. Start the engine and let it run until the electric fan turns on.
11. Turn off the engine and drain the water.
12. Flush the cooling system until clean water starts to drain.
13. Disconnect the hose again from the fitting of the intermediate coolant supply pipe to the throttle assembly.
14. Fill the engine cooling system by pouring coolant into the expansion tank until it starts to flow out of the throttle body fitting and the removed hose. When the liquid starts to flow out, put the hose back in place and secure it with a clamp.
15. Start the engine and warm it up to operating temperature (before turning on the fan). After this, stop the engine, check the coolant level and, if necessary, add it to the expansion tank slightly above the welded seam of the tank halves (it is indicated by two arrows applied to the wall of the expansion tank).
NOTE: While the engine is running, watch the coolant overheating warning light in the instrument cluster. If the light comes on and the radiator fan does not turn on, turn on the heater and check what kind of air is passing through it. If the heater is delivering warm air, the fan is most likely faulty, and if it is delivering cold air, an air lock has formed in the engine cooling system. To remove it, turn off the engine, let it cool down and unscrew the expansion tank cap. Start the engine, let it run for 3-5 minutes and tighten the tank cap.
USEFUL TIPS: To better fill the system without air locks, periodically squeeze the radiator hoses with your hand.
After several days of vehicle operation after replacing the coolant, check its level. Replenish the level if necessary.
If after a very short time the color of the fresh liquid turns brown, then you have poured in a fake, to which the manufacturer "forgot" to add corrosion inhibitors. In addition, one of the signs of a fake is a sudden complete discoloration of the liquid. The dye of high-quality cooling liquid is very stable and only darkens over time.
