Where to Add Insufficient Coolant?

[Hillary]

Insufficient coolant should be added in the engine coolant reservoir. Coolant can prevent scaling: High-quality coolant is made with distilled water and contains anti-scaling additives, which not only prevent scaling but also have descaling functions. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather parking. Coolant can prevent corrosion: Coolant not only does not cause corrosion to the engine cooling system but also has anti-corrosion and rust-removal functions. Engine antifreeze generally contains substances that lower the freezing point of water as antifreeze agents, ensuring the cooling system does not freeze in low-temperature conditions.
