Which antifreeze should I use for my 2006 Buick Lucerne?

Question

Accepted Answer

For a 2006 Buick Lucerne, it is recommended to use DEX-COOL antifreeze with a 50/50 mixture of clean water. The car holds 12.7 quarts of antifreeze for the initial fill. The antifreeze flows through the engine to prevent it from overheating or freezing and also safeguards against rust and corrosion. This coolant is expected to last for 5 years or 150,000 miles, whichever comes first. When topping up the fluid, ensure the engine is cool first. The price of the antifreeze ranges between $11 to $20, depending on the brand and location. The cost for a professional change can vary from $130 to $170 in service fees.
