Could you please tell me the type of coolant used in a 2003 Chevy Silverado?

Question

Accepted Answer

For a 2003 Chevrolet Silverado 1500, it is best to use orange Dex Cool 50/50 Pre-Diluted coolant. The initial fill-up requires about 15.2 quarts of fluid. While the manufacturer suggests changing the coolant every 100,000 miles, there have been concerns that waiting that long could lead to engine damage. In fact, a lawsuit was successfully filed by individuals who claimed that Dex-cool harmed their engines, recommending a coolant change every 50,000 miles instead. The labor cost for this service typically ranges from $100 to $120, plus additional charges for parts.
