Can Antifreeze Be Added Directly?
1 Answers
Antifreeze cannot be added directly; the engine cooling system needs to be cleaned before adding. The functions of antifreeze: 1. Provides anti-corrosion protection for cooling system components; 2. Prevents scale formation to avoid reducing the radiator's cooling efficiency; 3. Ensures the engine operates within the normal temperature range. The antifreeze level should be checked regularly, observing for any turbidity or sediment. If the level is below the minimum mark, it should be replenished promptly. If there is turbidity, the antifreeze should be replaced immediately. Different vehicle models use antifreeze of different colors, which should not be mixed. Before winter each year, the antifreeze's freezing point should be measured to ensure it is 15 to 20 degrees below the local minimum temperature.
