SOURCE: how do you change a

Just did this over the weekend with my 2001 Nissan Altima. First, remove the negative battery cable to prevent shorting. Drain the radiator by removing the drain screw. To gain access to the water pump, I had to remove the upper radiator hose to the engine, unattach the reserve tank hose from the radiator and take out the reserve tank, remove the alternator and the lower alternator bracket because it blocks access to one of the water pump bolts and move the serpentine belt out of the way. This should give you free access to the six bolts that attach the water pump. You will probably have to hit the water pump with a rubber mallet or some other tool to break the sealant on the water pump, but it should then just come off. The hardest part of the job for me was removing the bolts for the alternator bracket because they were on extremely tight. Reinstall your new water pump after applying sealant to all parts that will attach to the bracket, and your ready to put it all back together. If you have the right tools, this should take probably 4 or 5 hours to complete.

There's a YouTube video at the link below showing replacement of the water pump and thermostat. It's lengthy, but at 29:40 and 30:18, it shows the cover bolted to the block. It should give you a pretty good idea of the orientation of the cover and the water pump.
According to information I found elsewhere, 1993-2001 is all the same.

sounds like where the water pump meets the engine has warped or the gasket has been blown. Since the water pump has to come out anyway to fix it then i would suggest replacing the pump. It is 30 to 40 more.

You have a timing chain no belt. Changing is not necessary unless there is a failure. Water pump will need changing when it leaks.
