What brand is the original Buick antifreeze?
2 Answers
Buick's original antifreeze is DEX-COOL. What is antifreeze: The full name of antifreeze should be antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or freezing the engine cylinder block or head when the car is parked in cold winter. The role of antifreeze: Antifreeze is a kind of coolant with special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent performance such as antifreeze in winter, anti-boiling in summer, anti-scaling and anti-corrosion all year round. Can antifreeze be mixed: The same brand of antifreeze must be used. Different brands of antifreeze have different production formulas. If mixed, chemical reactions are likely to occur between multiple additives, causing the additives to fail. How to choose antifreeze: The basic indicators of antifreeze are freezing point and boiling point. The freezing points of antifreeze on the market include -15℃, -25℃, -30℃, -40℃ and other specifications. Generally, it is advisable to choose one that is more than 10℃ lower than the lowest temperature in the area.
As a car owner who frequently performs DIY maintenance, I've noticed that the original coolant for Buick is usually the AcDelco brand, which is a dedicated series for General Motors vehicles. This coolant uses the Dex-Cool formula, specifically designed for Buick and other GM models, effectively preventing radiator corrosion and engine overheating. The reason I use original parts is that they match the engine cooling system, avoiding potential issues like water pump leaks or cooling problems that other brands might cause. Regularly checking the coolant color—Dex-Cool is orange or red—and its freezing point is crucial. It's generally recommended to replace it every two years or 50,000 kilometers. When changing it myself, I always follow the manual to ensure the system is thoroughly drained. This kind of maintenance keeps the car running smoothly.
