Blue BMW Coolant - discuss....

[Wh33lhop]

I'm running on distilled water until I find all my coolant leaks. I just got another 3.5 gallons (like $3) in preparation for pulling my radiator. When I'm satisfied that it's leak-free I'll probably put some good coolant and some water wetter in there.

If I have no overheating problems, watter wetter would be pointless for me correct? Just curious because I'm flushing my coolant tomorrow, just wondering if I should consider it.

Water wetter can't hurt, extra cooling capacity for when you need it.

blue = cold , rite?

I think they just wanted to be different, we had a car come in the shop and saw blue dripping and thought it was washer fluid, wrong water pump was leaking! We were like huh...

That is because you are a retard.

I use whatevers on sale at autozone and hose water. Unless you personally put the coolant in your car and think you have anything better in there you're dreaming.

[Adrian_Visser]

I like the filtered used coolant you can buy at pick a part. It's brownish green mmm mmm so you know it's gotta be good. You can add some blue dye if you want it to be blue...

I like it. Has done we good so far.

hrm...water? its almost free, water is the main cooling additive, it doesn't kill the environment wen i dump it on the street, and in LA it doesn't drop below freezing.

if i run coolant/antifreeze its usually 30% or less. wal-mart special, non-premix.

"blue" is supposed to be for BMW engines since it is "phosphate free" and doesn't corrode my cyl head. whatever.

Have fun with that. I did that in the Nova and eventually it rusted through the top fins of the radiator and I have to top that shit off all the time. At least throw some Water Wetter in there to keep rust away.

I use the green stuff and our reverse osmosis water. Seems to work in everything else with aluminum heads / iron blocks, and iron heads / iron blocks too.

I'd consider using the blue, but the local dealer is a really douchey group of people, and it's not worth the 2 hour trip to go to the nice dealer for coolant.

Mercedes factory coolant is what I TRY to use whenever I can. I love looking at Mercedes with 15 year old coolant and all components looking brand spanking new.

[nando]

it's like $6 extra for BMW coolant for 2 years.. it's not just the aluminum/iron issue, but BMW uses a lot of plastic in their cooling systems. I don't buy it locally, I've always had it shipped with things like brake fluid. Mercedes coolant would also be acceptable.

those of you running tap water in your cooling system are morons. Distilled water costs $1 a gallon.

Yeah. Blue just tastes colder.

This is a great recipe:

1oz blue BMW coolant, used 8 years, r3v style
1oz Malibu
1 dash bitters
4oz pineapple juice





EDIT: Just kidding. DO NOT DRINK THIS. IT IS POISONOUS. THANKS.

I was going to buy prestone Dex-Cool certified stuff this week for my 24v swap since the dealer is so far away and it is phosphate free as well. Thanks to this thread i decided to do some research on GM's Dex-Cool. A quick google search revealed that GM has a class action law suit against them for their Dex-cool corroding aluminum. I think i'll take the trip and get me that blue drank :)

* This has been bothering me though: My car had a headgasket replaced before i owned it at one of the dealers here in Toronto and the coolant has not been changed since. The coolant they put in was green. Is the blue stuff a more recent addition or did our cars come with it from the factory?

That's for sure. See if they fill their batteries with tap water.

But paying $1 / gallon for water? Seriously? Reverse osmosis is fine, and costs what, $.39 at the grocery store? Less if you have your own system.

I know it's low in minerals; after evaporating a few thousand gallons of it in a stainless pan on the wood stove this winter, there's almost nothing left over.
