How do you open the radiator in your Hyundai excel?

To open the radiator in your Hyundai Excel, first make sure the engine is cool to avoid burns. Locate the radiator cap, which is usually on top of the radiator, and turn it counterclockwise to release any built-up pressure. Once it's safe, you can fully remove the cap to access the coolant. Always check the owner's manual for specific instructions related to your model.
