Dex-Cool is the factory-recommended coolant for many GM vehicles, including the 2002 Chevy models. It has a longer lifespan than traditional green antifreeze and provides good protection against corrosion. However, some users have reported issues with Dex-Cool, such as sludge formation if not replaced properly or mixed with other coolants. Regular maintenance and adhering to the recommended service intervals are essential for optimal performance.
