Previa coolant hose leak and valve cover leak have been resolved. Today's priorities: both drive belts and the wallet flushes.
The wallet flushes are complete.
I only used the finest-quality parts for this 31 yr old beast. Maybe I’ll sell it to
@Bill7 
The engine coolant was drained and refilled twice - each drain removed 8.5 out of the 12 QTs. First time was when I was replaced the water pump, second time was when the hose decided to leak. So, the system should be >90% new coolant. I used a vacuum filler to refill since this van can be a major pain to burp.
I think I forgot to document the last transmission fluid exchange - the fluid looks unusually clean. Oh well.
Fluid level is perfect after a 20 mile highway test drive.
Apparently the last brake fluid flush was in 2014.
Shame on me.
I used up my two open bottles of Honda DOT3 and Toyota DOT3 from March to flush out the reservoir (fluid was black) and used a new 12oz bottle of Advics DOT3 to finish off each caliper. For the fluid exchange, I used my pneumatic vacuum bleeder, followed by old-fashioned manual bleeding.
@atikovi may approve of this final result.
I forgot to take pictures of the rear differential fluid service but I can assure you that it was done. The fluid had been in there for 50K (M1) and “appeared” more discolored than I expected. I will say that the Valvoline flex-fill packs are a game changer.
Last, but not least. A quality wallet flush is not complete without an oil additive.
(For the record, I DID evacuate some oil via the dipstick tube before adding.)
