Michael---With no real "weather" to deal with in Hawaii, your only
concern should be boiling and corrosion protection. A Prestone (or
similar brand) an approximate mix of 33% product and 67% water should
work well.
For a complete flushing of the block, take out the thermostat and run
the engine with a fresh water supply. (Not necessary unless you suspect
a lot of rust is present)
If you want to take out the radiator to back-flush it, it's easy enough
to do. Let the water in the block drain out during this proceedure. Use
compressed air thru the thermostat housing for the most evacuation.
All of this could leave the system with air pockets, so to get rid of
these I run the engine, fully warmed, with the radiator cap removed,
until no more bubbles are present in the return flow.

Listers:
I plan to change the coolant on the 6 this weekend. I have the Haynes
manual and the procedure looks straightforward. Two questions:
1. Is there any special measure I should take when re-filling to
make sure I don't get air in the system? Is this a big problem?
2. The manual mentions using anti-freeze with a "glycerine or
ethylene base." I think that typical anti-freeze (Prestone or the like)
uses a polyethylene glycol base. Is this OK? I do plan to use distilled
water, rather than "rain water" mentioned in the manual.
Thanks, and happy holidays to all.
