Question about 1991 Buick Riviera
Disconnect battery, drain the radiator of coolant, move it out of the
way, then remove the fan shroud that has a top section and a bottom
section, once you have that out of the way, remove the upper and lower
radiator hoses, the heater hoses that connect to the water pump too,
now remove the fan from the water pump
you might have either ac, alternator or power steering in the way, and have other bolts. but basically after you have all the rest of the engine removed it is easy to get the water pump off. clean all new surface area's where gaskets touch , use indian head gasket sealer, its the best kind, when you put the new water pump on the engine make sure all the old gaskets are removed and wire brush the water pump housing, use gasket sealer, let it dry ,then put all the hoses back on, the power steering, alternator etc, all back in place, fill up the radiator, let it get to 190% temp, and make sure the thermostat opens, then you know everythings working,

About 8, if you are methodical you should be ok. You will probably have to remove the cam belt. If you do you need a tool to hold the cams-the tool is basically a flat plate +/- 400 mm long and about 6mm thick which slots into the rear of the cams when engine is in the correct position and on tdc.

so i just replaced my water pump today on the same car, mine is a 5.9 magnum. I drained the whole system before i started working on it, next you have to take off the fan, if you look on the inner side of the fan there is a big nut there, in order to loosen that i put to bolts into the holes on the water pump pulley and used a thin screwdriver for leverage, while putting pressure on that, i loosened the nut, be careful not to slip cuz those fan blades are dangerous. but once you have removed that nut from the pulley take out the four bolts holding on the housing, pull the fan and the housing out at the same time. next remove the belt, after that is done, disconnect the hoses from the water pump, there are three, one on each side and one on top. there are a total of eight bolts holding the pump on, keep track of them because they are different sizes. But that is how i removed mine. It was all farely simple i am a girl and i managed to do it so i think you should be fine. Hope it works for you becuase it didnt work for me, i now think that it is my head leaking, if you know anything about that let me know.

Water pump is locate on the front center of the engine.
I will rate water pump change as a 7/10 in difficulty scale.
You should check for special tool(s) requirement from the library before you start.
It's a good time to change the drive belt at the same time.
50/50 coolant mix is fine.
If you haul heavy load or in cold climate then bump it up to 60/40 mix
DO NOT FORGET to find or draw the belt routing diagram before you undo the tension.
A 30 second sketch will save you a lot of time.
