- Pull the hood release under the dashboard until you hear the Chevrolet hood pop open. Then, release the hood safety latch at the front of your vehicle.
- Locate the coolant reservoir (tank) in the engine bay. You can check the engine coolant level simply by looking at the side of the tank. If the level is below the minimum mark, you must add coolant, or your vehicle may overheat. Do not open the cap when the engine is hot.

- Turn the ignition on, but don’t start the engine, and check the engine temperature. Wait for the engine to cool down, which may take a while. Keep theignition, lights, and radio off to avoid draining the battery.

- Remove the cap by turning it slowly counterclockwise.

- Add engine coolant/antifreeze. Only add the coolant type recommended by Chevrolet. In an emergency, any color coolant is okay. When possible, flush the system and fill it with the recommended Chevrolet coolant.
