What color coolant should you use on a 1999 Chevy Tahoe?
The 1999 Chevy Tahoe should use Dex-Cool, which is a shade of orange or reddish-orange. However, it's crucial to check your owner's manual for the specific coolant recommendation. While Dex-Cool was common, GM has made changes over the years, and using the incorrect coolant can damage your engine. Don't rely solely on color; always check your manual for the exact specifications.
