Then after you've done the valley pan or had it done then use coolant. Water itself is an excellent coolant unless you're worried about 'freezing' don't use additional coolant...water will work great. Valley pans are expensive to replace so save your $ for that job...then do the whole shabang...IMHO

And follow the procedure below to top off the coolant level

A newbie's first post was asking what coolant to use, so, for the record, I pointed him to this "What Coolant you using?" thread, which I consider the canonical thread for E39 coolant:
- E39 (1997 - 2003) > Toping off Coolant

For the cross-linked record, a short history of Zerex (Zerez, Zerone, etc.) is in this thread today:
> E39 (1997 - 2003) > A coolant I came across

EDIT: Another 'what coolant' thread posted today:

Tried WaterWetter with no measurable difference in temp. My indy says it's a waste. Just use 50/50 BMW coolant and water plus maintain the cooling system.

I'm not vouching for what is said in this video (after all, it's put on by a magazine collaborating with a coolant manufacturer); but it's an hour all about coolants, which contains some interesting information.

PS: Since there are three religious sects when it comes to all BMW fluids, you'll never put the argument to rest - all you can do is figure out which sect you personally belong to.
1. Only BMW recommendatrions
2. BMW recommendations plus anything that meets BMW standards
3. BMW recommendations plus anything meeting BMW standards plus logical alternatives

For the crosslinked record, the "what coolant" topic came up again today, over here:

Thanks guys.

I've been trying to figure out why the 'what coolant' comes up, and specifically why anyone would think to only consider BMW coolant, when it finally dawned upon me that the coolant choice, is based on personality just as much as almost every other choice we make.

Here's an example which was posted today

Simple, any of these readily available three will work: Preston Extended Life (Green)5-150/Valvolin Zerex G-05/Peake Green. Mix in pure water from anywhere at less than $1 per gallon (if coolant not premixed) and ready to go. For those asking about water wetter and other coolant additives: As far as I know, BMW coolant contains a water wetter.

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

In addition, print this and put it in your glovebox:

Mein Auto: E39 530i
Hi. First post here from a long time BMW tragic, just added an E39 530i to the collection...great machine...

Since BMW doesn't publicly release the coolant spec (Bluebee had to get it from the depths of the TIS), it makes me wonder if it gets changed over time to suit the latest models. Similar to engine oil, where I've heard that dealers don't stock E36 M3 grade any more, they just throw in what's closest. Is their mystery coolant the same as it was 15 years ago? Or is the current brew better for our engines? Or worse? We'll probably never know.

PS this is the first time I've ever experienced Aussie BMW dealer prices that aren't absolutely gouging! (~US$15 for 1.5 quarts, which isn't too bad)

For the record, there was yet another thread on Evans NPG today ...
