Replacing a 97 Ford Taurus 3.0 v6 Vulcan water pump is not very difficult. You can do the job with a few basic hand tools in about 2 hours.
I replaced my Taurus water pump one night starting at 8:00PM in my driveway, in the dark, using a droplight. I finished up around 10:00PM, which included back flushing the heater core and flushing the radiator. The job would have been much faster in the daylight, plus the flushing added more time and effort.
NOTE: When replacing the 3.0 Ford Vulcan water pump on the 1997 Taurus, you DO NOT have to remove the alternator.

1997 Ford Taurus 3.0 GL Water Pump Replacement Procedure
1) Remove the plastic radiator reservoir on the passenger side. One bolt and one nut holds the tank in place. Remove the big pinch clamp and larger hose on the reservoir bottom (that goes to the radiator). Remove the 2 small hoses on top (2 small pinch clamps).
2) LOOSEN (but don’t remove) the 4 small 12mm bolts in the water pump pulley with a wrench.
3) Remove the belt tensioner. Undo the belt by using a wrench on the pulley bolt, to pivot the tensioner to make slack in the belt. Remove the belt. Unbolt the tensioner. This is a 15 or 16mm bolt.
4) Remove the water pump pulley (bolts were loosened in step #2 above).
5) Remove the idler pulley. Remove the single bolt and the idler comes off.
6) Unplug the crank sensor to get the wire out of the way.
7) Remove the two little support brackets that attach to the water pump.
8 ) Remove the hose from the water pump. You can also remove the lower radiator hose if needed.
9) Loosen all the bolts (11 bolts) on the water pump. Some are small, some are large. Do not remove the bolts yet.
10) Lay your NEW water pump nearby. Remove each bolt from the old water pump one by one. As you take them out to the old pump, insert them into the correct hole of the NEW water pump. That way, you will not get their locations mixed up!
11) Once al the bolts are taken out, remove the old water pump from the engine by gently prying on it, WITHOUT disturbing the timing cover underneath it.
12) Lay the OLD waterpump beside the NEW water pump. Compare them to make sure they look the same! Move all the bolts from the NEW pump to the old pump, keeping them in their correct locations.
13) Scrap/clean the old water pump gasket from the timing cover (where the old water pump was attached).
14) Coat your NEW water pump gasket lightly with some gasket sealer. Put it on the bottom of your new water pump.
15) Use the bolts (in the holes of the old pump) to bolt the new pump onto the engine. After you install ALL the water pump bolts… carefully tighten them down evenly, in a criss cross pattern. Do not over-tighten/strip the bolts.
16) Finish installing all of the other items in reverse order of disassembly.
Hopefully, changing your 97 Taurus 3.0 water pump yourself, will save you time and money. It is NOT a difficult job at all. The hardest part is cleaning/scraping the old gasket and keeping all the water pump bolts in the correct holes! Don’t forget to plug the crank sensor wire back in!
