whats so special about bmw coolant

I am going to get a coolant change and wanted to know whats so special about the BMW coolant.
I hear that you have to get it from BMW and mix it 50/50 with distilled water then put it in.

As anyone put regular antifreeze in there? Or is the genuine bmw coolant necessary for our cars?

well from what I was told the BMW stuff has no phosphates or nitrates which will mess up the seals and gaskets so just get coolant without those ingredients and you should be OK

you also have to make sure that your new coolant wont start to create caviatation around the cylinders....the block is aluminum, and any air bullbles that form can be detremental to the walls of the cylinders.....i would look at the ingredients of both before switching it out.....

you can use other brand coolants as long as they meet the specifications outlined in the manual.

Some Antizees have no corrosion inhibitors, meaning they have no protection agaisnt corrosion. Also some cheap brandnames have corrosive agents and can corrode your aluminum block. Some will leave residues on the coolant passages leading to overheating or hotspots.

BMW coolant is silicate free, phosphate free, amine free, and borate free. This keeps things nice and happy amongst all the dissimilar metals, plastics, seals and rubber in the cooling system. It is sourced from Pentosin, a very reputable European fluids manufacturer and supplier along with development from BASF. It is relatively expensive for this reason.

Granted it is twice to three times what OTC coolant is at the local parts superstore but coolant only needs to be changed every 2~4 years. Amortize the cost difference over that time period and it comes out to .60 a month for the two year interval. Can't even get a Happy Meal for that. I say feed your Bimmer well and use the OEM coolant.

Hey - I thought my coolant was low and tried to top it off with some coolant I picked up at the gas station (50/50 premix, generic). Long story short, it did not really need to be filled up like I thought and I only put maybe a cup in (at most). Should I be concerned at all about getting it flushed and refilled? It was listed as low silicate formula. I have never thought much about coolant other than making sure it is mixed with distilled water.

What's so special about BMW coolant?
It makes BMW a lot of profit!!!!!
They are all ethylene glycol and if used with distilled water, there is no problem with Prestone or similar long life anti-freeze. Prestone's bottle is trying to dispell the myth that everybody's stuff is different because the color is different. It's called MARKETING! Prestone can be "used with any color anti-freeze" It's mixed in mine with BMW coolant since going off maintenance warrantee and soon to be totally flushed.

I really don't get this - BMW, as well as the guys that write the tech columns for Roundel and Bimmer who have a lot more experience servicing BMWs than anyone on this forum, say only use BMW coolant. Frick guys, if you pay the dealer to flush your cooling system every 2 years it's $100, and maybe you buy a gallon to keep in the garage for top offs for $30. Other than oil, its' what keeps your engine alive.

Why all the hand wringing over this given the cost of your car - I mean there are people here that spend hundreds of dollars on bling and stereos, yet sweat paying $100 for the right coolant. A tricked out car with a blown headgasket and $3000 bill to get fixed or failed radiator sitting on the freeway doesn't sound too cool to me.......................

Why is BMW coolant special you ask?




Because it's a pretty blue color. Blue makes me happy. Ah look at the blue.

I was hoping someone would see my question and answer it. I would gladly buy BMW coolant, but it is not like the stuff is available at the local Exxon (which, incidently, is where I picked up some no-name stuff that I used). Anyway, I ended up putting less than a cup in the car. Should that even be a consideration as far as flushing out?

In addition, I would have to say that the fact that the BMW coolant is labeled "BMW" is not important - I suppose it is the characteristics. The same stuff is surely available from other vendors, as they are the ones who supply BMW no doubt. BMW does not have a coolant production factory. This reminds me of the BMW windshield threads.

george -may I call you george?- I'm pretty much in the same boat as you are. I put in Prestone (about 3 cups of anti-freeze + 1 cup tap water) in my coolant tank...even though it's for all makes and models, I am still going to have it flushed out and topped off next Wednesday at my dealer just to be safe. I suggest you do the same. This way, they can't ever blame engine problems on bad coolant g'luck!

Righto.

A little Prestone won't hurt your car. They all have to conform to the same minimum standards. I would use the BMW coolant and some nice distilled water when flushing the system, but for just a little top off, the green stuff won't hurt.

Speaking of which, I still have a gallon sitting in my living room. I should probably flush the coolant soon.

The coolant (or windshields) are certainly not made by BMW. However, I am sure in the auto industry as with many others, OEM agreements with the actual manufacturers of a product, can include exclusivity rights on the design / formulation, so that you can not buy exactly the same thing off the shelf.

By the way, if you were only a cup low, I would have just added some water, not another coolant...............

im not being picky about not spending money, i will go to pick it up from the dealership, i am just curious to ask why it has to be BMW coolant.

i mean almost all other cars let you use brands you can find from any local auto shop.
