    Its never a problem giving advice girl or guy, your questions are important, ask as many as you like. Now the drain plug/pet cock, if accesible,U gotta go underneath and being that this is a truck, safely look underneath the front area of the truck, whereby you can see the bottom of the radiator, and carefully, turn the drain plug,(its attached to the radiator normally black in color) most times if they have never been removed it will take some muscle,and the right tool.Aways turn the pet cock carefully most times this plug is made from plastic. When you get it a little loose have your drain pan underneath to catch old fluid. Make sure you put the right amount back in, and bleed the system to make sure all air is out.
