How to Check if the Antifreeze is Low?

[LaRemington]

To check if the antifreeze is low, observe the antifreeze warning light on the dashboard; if it illuminates, it indicates a lack of antifreeze. The functions of antifreeze are: 1. To provide anti-corrosion protection for components of the cooling system; 2. To prevent scale buildup, avoiding a reduction in the radiator's cooling efficiency; 3. To ensure the engine operates within the normal temperature range. The dangers of not replacing expired antifreeze include: 1. Evaporation of water in the antifreeze, leading to changes in the antifreeze's freezing point and affecting its performance; 2. Loss of anti-corrosion, anti-rust, and rust-removal functions for the engine, impacting the engine's lifespan; 3. Increased viscosity, reducing cooling efficiency.
