How often should the antifreeze be replaced in a Buick Regal?

[AnnieMarie]

The antifreeze replacement interval for the Buick Regal is every 5 years or 240,000 kilometers. Below are detailed explanations about automotive antifreeze: 1. Functions: It prevents components from system failures or cracking due to cooling issues in cold weather, manages rust prevention, avoids excessive scale buildup that could clog pipelines, and provides anti-corrosion, anti-scaling, anti-boiling, anti-freezing, and anti-rust capabilities. 2. Primary Uses: Antifreeze, fully named antifreeze coolant, is a coolant with antifreeze properties that prevents the coolant from freezing and expanding to crack the radiator or damage the engine cylinder block or head during cold winter parking. Antifreeze is a specially formulated coolant additive primarily used in liquid-cooled engine cooling systems, with its freezing point varying according to the concentration of ethylene glycol in the aqueous solution.
