Expansion tank
Expansion tank (indicated by an arrow) white, installed behind the radiator, connected by a hose to the base of the radiator filler cap.
All vehicles covered in this manual have a closed pressurized, pressurized cooling system.
As the coolant heats up during engine operation, the filler neck fluid is forced out into the expansion tank. As the engine cools, the coolant flows back into the cooling system.
The coolant level should be checked regularly. The level must be between the marks on the tank Full (Full) and Low (Lower). The level will change depending on the engine temperature. On a cold engine, the coolant level should be slightly above the Low mark. On a warm engine, the level should be at or near the Full mark.
1. If the level position does not correspond to the specified one, then after the liquid in the tank has cooled, remove the plug and add coolant to the Full mark. Only ethylene glycol and water-based liquids should be topped up; it is forbidden to add anti-corrosion additives yourself. The recommended composition of the liquid in the cooling system is indicated in the vehicle operating instructions.
2. If it is necessary to unscrew the radiator filler cap, then wait for the system to cool completely, then wrap the plug with a thick layer of rags and turn it until it stops. When steam appears, wait until the liquid has cooled completely, then unscrew the plug.
3. When checking the fluid level, always keep an eye on its condition. It should be relatively transparent. If the liquid has turned brown or rusty, it should be replaced after flushing the cooling system. The anti-corrosion properties are depleted over time, although the fluid may retain a satisfactory appearance.
4. Do not allow antifreeze to come into contact with skin or painted vehicle surfaces. In case of contact, rinse immediately with plenty of water.
5. If after a short period of time after topping up the liquid level drops, then the system may be leaking. Check the radiator, hoses, filler cap, drain plugs, and water pump. If there are no obvious signs of a leak, then check the radiator cap by handing it over to a car service workshop.
