What Coolant Is In Your BMW?

[genphreak]

i spank off in mine sorta like evans

Like Evan's? Hmmm a cloudy mix is normally a bad sign. I guess not in your case Winfred... increases cold-weather protection perhaps?

I went to the dealer when i bought coolant last, they gave me a red Castrol coolant, I asked after the Bmw cool blue, but he said this red castrol is the only coolant they used there.

We do?

I used a red Toyota compatible replacement from a parts place in my gf's mum's Toyota, but after the worries I've learned about it will be going back to dealer-supplied concentrate at the end of the year. (I've decided to trust it for 12 months). My Bimmer however is staying Blue now . After having seen inside it I got it, now I will only accept the factory -level protection for my baby. I don't like replacing things unecessarily. Nick

green + red = blobs
isn't red the organic as opposed to ethylene glycol based coolant which is green/blue

No kidding. I did this in my old MKIII Golf and it slowly turned brown... though not blobby

Since SAAB blue stuff, they also have an orange, is the same Valvoline Zerex G-48 as BMW, at least here in the U.S., and being that it is 50 to 60% Cheaper, that's what I will be at my next coolant change!

Well, since this thread got more replies than mine that probably brought about this poll in the first place. I called the dealer today and spoke to the service manager and his shop foreman. Both gave me the same answer. Prestone's green coolant is phosphate free and something else free, and is safe to use in an M50. They also mentioned to do the standard coolant flush service every two years like the manual says. I wanted a reason to take back the green stuff for blue, but at twice the cost, and with the same chemical make up more or less, it's not worth it. The dealer uses the green stuff in M50's, so obviously we can too.

The Blue stuff they said was definitely what they use on the M60 and M62's though.
