I have a 1996 dodge ram 1500 5.2 liter and I need to replace the radiator.how do I do that and where do I begin?

Begin by disconnecting the negative battery cable, draining the coolant into a suitable container, and disconnecting the radiator hoses from the radiator. Then, unfasten the radiator fan, shroud, transmission lines, and radiator. After buttoning everything up, refill with a 50/50 mixture of the proper antifreeze and distilled water.
