Wait, we have to use BMW specific coolant too? I just refilled mine with Prestone after doing this the other day.

I have been told by EVERYONE that using anything but BMW radiator fluid is a big time NO NO. I used the BMW fluid and distilled water.

I have used the DEX Cool (I think by prestone) for years on my other BMW's. Never a problem. I even deleted the fan on my E36 and still never a problem. Just make sure the coolant is safe for "all metals." Dont get teh cheap green junk though.

I don't recall exactly what, but there is something about BMW coolant that is different from most of the off the shelf brands. I think it has to do with silicates, but honestly, I don't recall if it is supposed to have them or not. Whatever it is, it maintains the health of your water pump.

With that in mind, it is much like oil or any other part - if you can find a comparable aftermarket product that meets the same specs/requirements, there is no reason not to use it, but I wouldn't grab a random bottle off the shelf and hope it works out.

You should use BMW approved fluid. Too many variables with seals and metals for me to take the chance just to save a few dollars. If you go aftermarket, I'd seriously look into Zerex G-05. Supposedly it's factory fill for many European cars these days, only w/o the huge dealer markup. Zerex G 05. There is a Pat Bedard article on this on Car and Driver online.

So how hard would it be for me to drain ALL of the coolant and refill it with the BMW stuff? When we did the t-stat replacement, we didn't drain the block, so right now there's just an amalgamation of fluids in there - old BMW coolant, new Prestone coolant, and DI water. I really don't want to have to take it to someone; that's the whole reason I did it myself. I guess I should have researched the coolant issue beforehand.

Edit: After some research, it looks like I just have to pull the radiator plug and the plugs on both sides of the block and refill 50/50 with coolant/water. I need 6.5 quarts of coolant since we have a 13 quart capacity, right?

You've got the drain method down. Just remember that the radiator drain plug doesn't unscrew the whole way (1/4 turn then pull down I think) - ask me how I know... I bought 2 gallons and had plenty, so you're 13quart number sounds close...

No suggesting allowed - take a stand!

"You must use new crush washers when replacing the block plugs since crush washers are not reusable"

Yes Douglas. It is MANDITORY that if you drain from the block you get new crush washers. That would suck to get the thing drained all the way then only to realize you didnt buy 2 $.60 parts. So while youre buying the MANDITORY OEM coolant ask them for some crush washers for the block.
