Not familiar with your particular vehicle but most cars and trucks have a petcock ("T" shaped fitting) on the bottom of the radiator usually on the drivers side. You will needs a pair of pliers and CAREFULLY turn the petcock counter clockwise to open.

The radiator for the engine coolant system is located at the

condensor will be in front of the radiator )

At the radiator or at the coolant resivoir.
