BMW Coolant

[charlie]

so what do you sue Winfred? I trust your opinion as should everyone else...

certain coolants contain plasticizers which break down the plastic when they get old, and the wonderful godlike bmw blue is one of them (when the neck snaps off the radiator or bottle crumbles you can see the intrusion into the plastic), ill see if i still have the info i posted a year or two ago that somewhat explains the different coolants and post it when i get home, bmw blue or dexcool will never grace my cars or anything in my shop, but if using factory blessed fluids blows your skirt up go for it, i hate these pissing match fluid threads and after posting the article from master tech tonight will only watch this one for my amusement

Yes, that might be helpful, unless you simply enjoy pissing matches!

Maybe how you arrived at your determination, too, would be useful. I feel certain you covered that previously.

I thought you could use any as long as it was blue :-(

Green! Its called Ethylene Glycol, buy it as that and it`ll last forever, no additives, plasticisers or whatever, end.

Just joking. Additives?-Willing to bet ethylene glycol doesnt start off life green. Never had a problem with antifreeze making plastic brittle. Nitric acid on the other hand is a bugger for it. Cant see a queue to top up with it though

[Barney Paull-Edwards]

The green in it was a trace colour for locating leaks,originally for R-R Merlin engines,all alloy but with iron/steel bits, does not corrode either.

as long as its low silicate and phosphate it whould be ok right?

Have never understood the mania over this issue. Do a search if you want to see how often it comes up.

BMW blue is cheap and you only need 2 bottles (3 litres).

Use it and worry about something else that matters - like tyres.

I recently had a BMW Dealership flush and refill my coolant system with BMW Blue. The next day the upper hose popped off and i lost 4/5th of what had just been put in. I wasn't in the BMW parking lot so needing to drive i bought the first bottle of 50/50 i could find,PEAK i think,Green for sure and have been using that and Prestone since. I was going to try having the dealership refill me but honestly couldn't be bothered. Everyone says the current Green Ethylene Glycol coolants are safe. I don't mind revisiting issues to distill the knowledge base further. How many times is White Lighting distilled?
