Understanding G12 and G13 Antifreeze: Why Choosing the Right Coolant Matters

Antifreeze is one of the fundamental elements of your vehicle's engine cooling system, protecting the engine against temperature fluctuations. It prevents the engine coolant from freezing during winter months while stopping it from boiling over due to extreme heat in the summer.

When choosing antifreeze, it is crucial to select a type that complies specifically with your vehicle manufacturer's instructions. There are various types of antifreeze, such as G12 and G13, and these should never be mixed. Color differences indicate the chemical composition of the antifreeze; therefore, users should carefully examine their vehicle's technical manual to select the appropriate product.

Properly adjusting antifreeze ratios is also vital. Generally, a 50% antifreeze and 50% water mixture is ideal, though this ratio may be increased in favor of antifreeze in extremely cold regions. Using incorrect ratios can decrease engine efficiency and lead to malfunctions within the cooling system.

By performing regular antifreeze checks and following correct usage recommendations, you can enhance your vehicle's performance and ensure long-term durability.
