Need to find out where to add antifreeze to a 2006 H2 radiator

Coolant on your vehicle should be added to the reservoir that is located on the passenger side of the engine compartment. It will have a cap on top, that can be removed when the engine is cool, and allow for coolant to be added. Also, there should be marks molded into the side of the reservoir, that will show what the level should be, for both a cold, or hot engine.
