What is a step process to put in a radiator for this type of truck

Drain the cooling system.

Remove the hose clamp and pull the upper hose from the radiator

CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container.

Unscrew the top of the radiator from the radiator support

Remove the air conditioning condenser attaching screws from through the grille (if equipped)

Disconnect the negative battery cable.

Unscrew and move (or remove) the radiator shroud to give clearance for the radiator removal

Detach the upper hose from the radiator.

Unbolt the radiator once the shroud is out of the way

When completely detached, lift the radiator out of the vehicle-do not lay it flat on the finned surface

Remove the shroud mounting nuts and position it out of the way.

Remove the radiator top mounting screws. If equipped with air conditioning, remove the condenser attaching screws, accessible through the grille. Do not disconnect any air conditioning lines.

Raise the vehicle and support it.

Disconnect and plug the automatic transmission cooler lines and cap the openings in the cooler.
Hold the radiator in place and remove the lower mounting screws. Carefully lift it up and out of the truck.

To install:

Hold the radiator in place and install the lower mounting screws.
Connect the automatic transmission cooler lines.
Install the radiator top mounting screws. If equipped with air conditioning, install the condenser attaching screws, accessible through the grille.
Install the shroud mounting nuts.
Connect the upper hose from the radiator.
Connect the negative battery cable.
Fill the cooling system.
Check all fluid levels and run the engine, making sure there are no leaks.

Let me know if this helps.
