Where do you put the radiator fluid in a Chevy 2004 silverado 2500hd?

The radiator fluid reservoir on a 2004 Chevy Silverado 2500HD is typically located under the hood, near the radiator itself. It's usually a translucent plastic reservoir with markings indicating minimum and maximum fill levels. It might be white, tan, or clear. Look for a cap that says "Coolant" or has a similar marking.

However, it's crucial to check your owner's manual. The exact location might vary slightly depending on the specific engine and options your truck has. Your owner's manual will have diagrams and specifics for your vehicle. Don't just rely on general information; the manual will ensure you add fluid to the correct location and avoid mistakes.
