Maintaining the cooling system in your GMC vehicle is crucial for its performance and longevity. Antifreeze, also known as engine coolant, plays a vital role in regulating your engine’s temperature and preventing it from freezing in cold weather. Here’s what GMC owners need to know about selecting the right antifreeze.
Understanding Antifreeze Types
Antifreeze comes in various types, each formulated with specific additives to protect your engine and cooling system:
- IAT (Inorganic Additive Technology): Traditional green coolant, suitable for older models.
- OAT (Organic Acid Technology): Contains organic acids for corrosion resistance, longer service life, and environmental friendliness.
- HOAT (Hybrid Organic Acid Technology): Combines IAT and OAT benefits, often used in vehicles with aluminum components².
Choosing the Right Antifreeze for Your GMC
For GMC vehicles, it’s essential to use the recommended type of antifreeze to avoid chemical reactions that could lead to deposits or clogging. The right antifreeze will contain the best corrosion inhibitors for your engine. GMC typically recommends Dex-Cool antifreeze, which is an OAT coolant specifically designed for GM vehicles³.
Top Antifreeze Choices for GMC
Here are some of the best antifreeze options for GMC vehicles:
- PEAK CleanGuard Technology Universal Antifreeze and Coolant: Available in both ready-to-use and concentrate forms.
- Prestone Dex-Cool Orange Antifreeze and Coolant: Specifically formulated for GM vehicles, including GMC, and available in concentrate and ready-to-use options¹.
Antifreeze Maintenance Tips
To ensure your GMC’s cooling system remains effective:
- Regular Checks: Inspect the coolant level and condition regularly.
- System Flush: Perform a cooling system flush every 5 years or as specified in your owner’s manual.
- Use Distilled Water: If mixing concentrate antifreeze, use distilled water to prevent mineral buildup.
Conclusion
Choosing the right antifreeze and maintaining your GMC’s cooling system can significantly impact your vehicle’s performance and durability. Always refer to your GMC’s owner’s manual for specific recommendations and consult with a professional mechanic if you have any doubts.
