Water leaking out of w140

Car: 1993 500 SEL; 125,000 miles

A) What is an Auxiliary water pump? Where is it?
B) What brand water pump should I buy?
C) Do you have directions on how to replace the pump, what else needs removed?
D) Where do I find the engine number?

Symptom: Water leaking. Noticeable by the large puddle under car and the two (2) gallons of fluid I have added in two days.

I'll get under the car today.

I'm thinking it is the water pump.

FastLane has offered several brands of pumps, at different prices.
1) Graf
2) Hepu
3) Laso

Comment: I will borrow a preasure tester free from local AutoZone today. See their web site for more info.
Thanks for the help
