What kind of antifreeze does a 2000 Chevy Tahoe use?

A 2000 Chevy Tahoe uses Dex-Cool, also known as GM-approved 50/50 coolant. It's crucial to use a coolant specifically designed for Dex-Cool systems, as using other types of antifreeze can cause damage. Do not mix Dex-Cool with other types of antifreeze.
