What type antifreeze do you use in a 2005 Chevy impala?

A 2005 Chevy Impala should use Dex-Cool antifreeze, also known as GM Dex-Cool or a compatible antifreeze. However, it's crucial to check your owner's manual. While Dex-Cool is the factory recommendation, some owners have successfully used other types of antifreeze (like conventional green antifreeze), but this is not generally recommended and can lead to issues with corrosion or other problems. Always prioritize the information found within your vehicle's owner's manual.
