Engine Cooling problem

I recently purchased a new radiator for my 1996 Cadillac Seville STS. Wanted to know how to do the job on my own. Diagram, step by step procedure. What tools will I be needing.

Here is what I have for a procedure from ALLDATA.
Service and Repair

Drain cooling system, then remove plastic radiator support cover.
Remove cooling fan, then the coolant reservoir hose at filler neck.
Disconnect upper and lower radiator hoses.
Disconnect oil cooler lines at radiator.
Remove radiator top support, then the radiator.
Reverse procedure to install.

You are going to have transmission cooler lines on the drivers side of the radiator, they are 16mm or 5/8" flare nut. The oil cooler lines I believe are 19mm or 7/8". The upper and lower hoses are 8mm or 5/16" screw drive unless they are spring clamps, they a pair of pliers can be used. If you are replacing the upper and lower hoses you could cut them if needed. The cooling fans and radiator supports are 10mm fasteners.
