ShoTimes still has a lot of good info...
!Always make sure the cooling system is not hot/pressurized prior to opening it!
The basic coolant flush procedure I use on all my cars is pretty easy (based on an old ShoTimes posting from Gary Morrell).
1. Drain rad (bottom of rad, drivers side )
2. Pull lower rad hose from rad and drain what ever comes out (PITA on SHOs)
3. Pull Tstat, reinstall housing - without Tstat!!
4. Pull upper rad hose from rad.
5. Put garden hose into upper rad hose and tape in pace with good ol' duct tape.
6. Place buckets under upper rad port to catch flushing overflow
7. Turn on hose and flush until clear.
8. Drain rad again, lower rad hose, and put Tstat back in. Reconnect upper rad hose
Fill with premixed coolant (50/50 for warmer climates, 60/40 up my way).
Start and run for a few minutes, refill rad as needed. Fill overflow bottle. Check it for the next couple days every morning to make sure the overflow bottle is full enough.
Always dispose of coolant properly - our local paper says flushing into a treated sewere (not septic) is OK.
YMMV, AFAIK, WIFM, etc
