Correction of concentration of antifreeze additive
It often happens that the concentration of the antifreeze additive decreases due to the addition of water to the cooling system. In this case, you need to add antifreeze additive. By eye, approximately 3/4 liter is needed to reduce the freezing temperature by 10°C. It is best to fill in a coolant containing 50% antifreeze additive even in summer. This will avoid changing the antifreeze properties of the coolant. If you still need to improve the antifreeze properties, then:
1. Place a clean container under the radiator.
2. Loosen the drain screw or remove the lower radiator hose to allow the coolant to flow.
3. Drain 1-2 liters of coolant.
4. Attach the hose or tighten the drain screw.
5. Pour the required amount of antifreeze additive into the expansion tank and fill it to the required level with the previously drained coolant.
Note: Recommendation: If the antifreeze additive content is more than 60% in the coolant, its freezing temperature will increase again.
The antifreeze additive loses its properties if stored in an open container. In addition, it contains components that are harmful to health and can cause damage if in prolonged contact with the skin. Therefore, the antifreeze additive should be stored in a closed container and out of the reach of children.
