For a 2000 Chevy Silverado, you should use
Dex-Cool antifreeze. GM vehicles of that era were specifically designed to use this type of antifreeze, which is also often referred to as a HOAT (Hybrid Organic Acid Technology) coolant. Using a different type of antifreeze can lead to damage to the engine's cooling system components.
Important Note: While Dex-Cool is the recommended type, always check your owner's manual for the manufacturer's specific recommendation. The manual will provide the best and most accurate information for your particular vehicle.
