Recommendations. The manufacturer recommends the use of coolant (antifreeze) based on ethylene glycol. Check with the dealer - the seller of the car, the brand of liquid filled in your car.
Do not mix liquids of different colors from different manufacturers. If you need to add coolant, but you do not know the brand of liquid filled into the system, replace all the liquid in the cooling system.
Only use products from trusted manufacturers. Remember that the use of poor quality coolant leads to costly engine repairs!
Place the vehicle on a level surface before starting work.
Attention! Check the coolant level only on a cold engine.
The coolant is toxic, so be careful when handling it.
Do not fill the reservoir above the mark «MAX», since when the engine is running, its volume will increase.
When starting the engine, the expansion tank cap must be closed.
Keep an eye on the coolant level at all times. Its sharp decrease or increase should be a signal for an immediate check of the engine cooling system.
If the freshly poured antifreeze suddenly suddenly quickly changed color to brown, then you were sold a fake, in which «forgot» add corrosion inhibitors. Replace the fluid as soon as possible before it has had time to corrode the cooling system.

4. Wrap a stopper of a broad tank.
Attention! Screw the cap on the expansion tank tightly. The expansion tank is under pressure when the engine is running, so coolant may leak from under a loosely wrapped plug or the plug may be torn off.
