Dex-Cool, the orange coolant formulated for certain GM vehicles, should typically be changed every 5 years or 150,000 miles, whichever comes first. However, it's important to check the vehicle's owner manual for specific recommendations, as maintenance intervals may vary based on driving conditions and vehicle usage. Regularly inspecting coolant levels and condition can help ensure optimal engine performance and prevent potential issues.

About every 36000 miles or so. Even thou you have DexCool, which is recommended every 100k miles, don't do it. DexCool is death for a engine. Wish GM would just get rid of it, and go back to the good old reliable antifreeze.
