I used Peak Global LifeTime. Do some research on it and you'll find it meets every requirement. Buy the concentrate coolant and buy several gallons of distilled water.
I followed the procedure that was posted here earlier when I did this last year and marked it "fair" when I finished.

My thoughts after doing this last Feb.....
Level the car on ramps....I raised it around 5" on all 4 wheels so it would drain normally.
There are 2 big hoses leading to the radiators in the front. You'll want to disconnect them and drain while under there.
There are also two heater core smaller hoses to drain near the two larger ones that I just mentioned.
You may want to replace all those German clamps which are crappy when reused.
Be sure thatyour hoses are sound....you car is old and it they have not been replaced, you should do it.
I did a total refill with distilled water twice running it for 20+ min each time to flush it. Yep...do all the drains with each flush. When you refill, crawl under there and squeeze those big rad hoses a bunch of times to help burp out the air.
refill with coolant. Then top off with water.
I measured what I drained and compared to what I was putting back in to estimate sir pockets, etc.
This is a patient job. Takes days due to the cooldown needed to flush it.
I had the nose skin and stuff off when I did mine because I had a radiator to replace as well. I was able to drain the front points at the radiators as well, but you won't have to do that if you do a patient job flushing it.
Overall, I'd call the job a PITA, but worth it. If it never leaks, I would not touch it for at least 5 yrs.
