First of all,you need the removal tool which looks like this.
You need to remove the air filter housing and ducting to gain easy access to the pump.
Remove the shield covering the pulley and belt. The belt is easily removed by levering the tensioner pulley.
The water pump is located at the lower radiator hose manifold where you will also find the thermostat.Remove the manifold cover and you will see the water pump.
Insert the removal tool over the pump making sure it is locked in position.You will need to use a breaker bar on the removal tool and turn the tool CLOCKWISE to release the pump (1/4 turn), or if you imagine the breaker bar being vertical, push towards the windscreen of your car,it takes quite a bit of force to unseat the pump hence the use of a breaker bar.
Installing the new pump does not require as much torque as removing the old one.Tighten the new pump to 73 ft.lbs. making sure it is seated properly before tightening.
Don't forget to clean out the water pump housing prior to installing the new pump and don't forget to include a new water pump gasket and housing cover gasket.
It is also a good idea to install a new thermostat while you're at it.
Just as an aside, the Northstar is a 4.6 , not 4.8.

Hey man, it's not too bad. Discharge the A/C. Take out compressor, take out bracket, take out alternator. There will be 2 bolts on the top of the alternator which are kinda hard to get to. Then there are two bolts on the in side of the compressor and I believe 4 total on the front. Google an electric motor repair place in your area!!! I get mine rebuilt for $50 vs $300 form a parts store. Or, get a brush kit. I believe on those you don't even have to take the alternator apart, only the black cover on the back. There you go, $12 you did it yourself.

SOURCE: Hi, please can you tell
If I remember correctly it has somefhing to do with capacity. The best way to find out is check with a GM dealer to see if the part number for a 1993 is the same as a 1998
