To get at the seal, you need to remove the water pump which is a multi-step process eventually using a special tool to remove it, and the procedure is just too complicated for me to show all this here. I suggest you visit alldatadiy.com and sign up for your car.
Take off the plastic cover located near the top of the radiator if present.
Remove the protective shield located on top of the belt pulling the water pump. You will need to undo two 10mm nuts and one 10mm bolt.
Undo the 10mm nut that holds water pump housing togeter with the oil dipstick.
Take off the air intake assembly.
Move the PCM computer to one side, ensure that the module is safely placed.
Release the belt tensioner using a big flat screwdriver.
Remove the serpentine belt from the water pump pulley
Remove the upper radiator hose. This is held by a metal clamp. Use plyers to remove the clamp.
Remove also the clamp from the thermostat housing bypass hose, without removing the hose (you have to bleed coolant first).
Unscrew the four 10mm bolts that hold the water pump housing and letcoolant drain from water pump plug. At this point you can also removethe lower radiator hose to drain faster.
After coolant drains remove the water pump housing.
At this point you have to use a special Water Pump removal tool onwater pump cand turn clockwise until the pump is sliding off thehousing.
Remove the pump and the o-ring located inside the water pump housing.
Clean and grease the area, put a new o-ring and install back water pump housing
Install the new water pump using the special tool and following operations in reverse order.
You may need to use sealant tabs from a Cadillac or GM dealer. Here is what you need. Better going to your local dealer to get the best product for yourCadillac. You will also need a 3/8'' ratchet, socket and extensions
Youmay also need to replace the housing cover gasket. You will need toreplace the O-Ring, that usually comes with the new pump. When installing new pump you must also ensure that the new pump is aligned correctly,one of the tabs on the pump housing is different and will lock up the pump, so it must bealigned properly while installing.
Sounds like you got some bogus advice. First go to your local library and check out the repair manual that covers your vehicle. This manual will instruct you on how to carry out most all common repairs. The belt you reference is probably not the timing belt, but that's something you'll learn when you find the repair manual for your car. By the way you should have your own repair manual for your car. It's very valuable, and can give much needed info to help decide if you can do the repair you're contemplating (is in your experience level). You'll make things worse if you can't/won't follow instructions. Most repairs can be done by the owner (in my opinion). If you know basic hand tools and do this one thing - always read the instructions beforehand to be sure you understand what the particular repair entails. Also this will alert you to the need of any special tooling to complete your task. Once you find a repair manual at the library you can compare the different brands. Chilton manuals are very popular, but there are others out there, and you may prefer them. Good luck.

mcdevito75 here, Water pump replace on your car is a shop only job, a couple of speciall tools may be needed, you may also have to lift the engine an inch or so. Let your local repair shop handle this job.
I don't know how close this engine is to the Aurora engine, but I did mine. It did take a special tool, but I was able to rent it for free from Autozone. Overall, pretty easy to replace.
You need a special water pump tool. you can rent one from
Auto Zone. The water pump housing is the bottom
radiator hose on the right side of the engine. remove the hose and the
outer-caseing, the waterpump is now slightly visable. Use a .5 inch
rachet with the Special tool and turn clockwise.
