Thanks guys.
What coolant is best for you depends more on YOUR PERSONALITY than it does on your BMW (it's just a car, after all - and specifically, just an engine after all).
- Fundamental BMW decision-making religious camps (1) & motor oil Petrolism (1), coolant decisions (1), & gasoline dogma (1)

So, my recommendation is to start here, by understanding fluids used by most here:
- Glovebox printout: BMW E39 fluid summary printout for your glovebox (1)

Specifically for coolants:
- Coolant: Coolant, for engine, automatic transmission, power steering, and AC evaporator cooling (1) & bleeding (1) (2) (3) or refilling DIYs (1)

Here's a starter quote:

EPA reports show San Jose & NYC tap water easily fulfill these requirements. The BMW TIS expressly states additives are not helpful and are not recommended. BMW lists a score of recommended coolants in their BMW AG TIS 12.11.2007 18:55 which meet the BMW N 600 69.0 standard, some of which are BMW PN:81.22.9.407.454 1.5-liter; BMW PN:88.88.6.900.316 1 gallon; Castrol Anti-Freeze NF; BASF Glysantin Protect Plus G48, & Havoline AFC (BD04); but most of which are not easily found in the USA. Many Bimmerfesters recommend BMW coolant; however other Bimmerfesters recommend Prestone Extended Life 5/150, Valvoline Zerex G-05, and Service Pro Universal Formula. Others (e.g., chiefwej, aioros), have tested Evans NPG+ but be aware propanol entails a different maintenance philosophy than the aqueous fluids listed above and is not compatible with them. [Total Volume: 1997 I6=10.5 quarts (2.6 gallons), 1997 V8=12.0 quarts (3.0 gallons), 1998-2002 I6=11.1 quarts (2.8 gallons), 1998-2002 V8=12.7 quarts (3.2 gallons), 1997-2002 V8 with latent heater=13.5 quarts (3.4 gallons)]. Prestone says the only reason for phosphate free is the extremely high mineral content of water in Europe - and that in the USA, it's not needed. Replacement Interval: Every three years (Bentley page 020-9) or every four years (aforementioned BMW AG TIS) starting from date of manufacture (except for M-Power vehicles which have 3-year intervals). Note: Mixing BMW-recommended coolant brands is permissible; but mixing types is not permissible unless it's an emergency.
