It would've been far less effort to accept that home shop machines don't
need coolant systems, when some others were advising you earlier.

If you're destroying an excessive number of cutting tools because of cutting
heat problems, then you might need a coolant system.

If you're experiencing part dimension tolerance problems due to heat
generated in the workpieces, then you might need a coolant system.

Instead, you probably want a coolant system just because you want your lathe
to look like a real industrial machine (might be worth more at resale if the
uninformed buyer thinks he needs a coolant system).
Any sensible prospective buyer should be more interested in how the machine
has been lubricated during it's past usage.

Actually, all you're doing is wasting your time. Any brush-on or dribble
method of cutting tool lubricant (not coolant) would be adequate for any
normal lathe operation, for most home shop machines.

If you had read any of the related posts WRT the purpose of coolant systems,
and posts concerning what lathe owners do as far as applying cutting tool
lubricant (not coolant), you might be able to realize how useless a coolant
system is on a home shop lathe.

Due neglect and mismanagement, the coolant in my lathe finally went
bad after several months in the sump. I have to add here that I have
all ingredients for setting up both the skimmer, as well as aerator,
to run on two timers, something that I plan on doing soon. But as of
now, I want to make sure that I properly remove old coolant.

As far as I understand, I should try to really get rid of the harmful
bacterias that live in the present coolant. I have a easy to use water
pump that I can use for this purpose.

So my plan was, pump out the coolant, rince the sump a couple of times
with just hot water with some Simple Green, then put water with bleach
for an hour, and rinse some more. Would that seem to be a good plan?
