What is the recommended coolant for 2002 Chevy Suburban?

The recommended coolant for a 2002 Chevy Suburban is a Dex-Cool type coolant, or an equivalent 50/50 mix of ethylene glycol antifreeze and distilled water. However, it's crucial to check your owner's manual. GM changed coolant formulations over the years, and using the incorrect type could damage your engine. The owner's manual will specify the exact recommended coolant type and the proper mixture ratio.

If you can't locate your owner's manual, you can usually find a digital version online through the Chevrolet website or a reputable repair manual provider. Using the wrong coolant can lead to serious engine damage, so accuracy is paramount.
