Where is radiator cap for Chevy truck?

The radiator cap on a Chevy truck is located on the top of the radiator, usually towards the front of the engine compartment. It's often a pressure cap and might be black or a different color depending on the year and model of the truck. Look for a somewhat prominent, usually round cap near the top of the radiator, which is the largest component in that area. Be careful when locating and handling it, as the radiator and coolant inside are hot when the engine is running.
