I opened up the sump of the cold saw today and was quite amazed by the
accumulation of sediment comprised of old coalesced water soluble oil,
with metal chips.

One thing you might consider is buying a sump cleaner and running it for a
few hours. You may be able to buy a quart, which is more than enough .It's
mixed with water and circulated just like coolant. It's always a good idea
to remove all traces of old coolant to avoid starting bacterial growth as
quickly as you change the coolant.

Also----try to keep tramp oil out of the sump. Keep the coolant fresh by
aeration or regular circulation and free of oil and you'll be way ahead of
the game.
