Coolant fluid access question

XrayMD · 10th May 2003, 18:05

OK... this sounds stupid but, is the only access to the coolant fluid via removing the plastic cap on the white coolant overflow reservoir?

I've got some Redline Water Wetter I wanted to add to the coolant but that's the only place I see to add it and when I removed the cover, I could see that there wasn't enough room to add a whole bottle of the Water Wetter. Should I siphon off enough fluid from there first and then add the water wetter?

(Rob, I know I asked you this the other night, but that level hasn't changed and this just seemed odd to me!)

Thanks all!

By the lack of responses, I guess everyone is going to take a look under the hood!

I looked at my X5 and it's the same deal.

So, I siphoned off 12ozs. of coolant from the M5's reservoir and then added the 12ozs. of Water Wetter. I guess that's the only way to do it. BTW, I have to do the same with the X5 because it's filled to the max (but not overfilled).

Hey Steve,

I just found some Redline Water wetter in Aus.

They use it to cool computers. Go Figure.

Anyhow, after reading the site, I'm going to completely drain the radiator and replace it with Distilled water and RLWW.

We don't get snow here. Or vast weather changes.

Don’t know what’s in the Redline water wetter but does it have enough of the properties that anti-freeze has to protect the engine as far as corrosion and such? The recommended solution of anti-freeze to water does other things besides protect again temperature extremes of the fluid used in your radiator.

Steve,

i understand buddy...im not the complete M5 encyclopedia myself. Just cause i tell you something doesnt mean that im 100% correct, i would always consult the board.

Yeah Ken, according to their site, it makes you a cuppa as well.

They do warn however to have at least 20% for antifreeze properties as the Air-Con in summer can cause freezing.

Its anti boil and Anti-freeze properties aren't quite as good as the Glycol soloution but it prevents hot spots in the motor and removes heat more efficiantly. I would be careful using it in climates of extreme temperatures low and high, but its very stable here so bring on the better coolig for increased spark.

Oh yeah its Anti-corrosive abilities are actually higher. And it doesn't bubble or foam as much.

I had to refresh this thread, since it was getting to the very bottom.
I also would like to add a bottle of PURPLE-ICE into the radiator but the darn thing is full to its top cap area. How would I add this 16 oz. bottle into the radiator? Do I have to extract the antifreeze out inoder to add the stuff or is there another way to do this???
Thanks Guys!

Robert,

you would need to take out some of the antifreeze that is already in the tank to make room for the new stuff. This is that I had to do with mine.

Just got back from a drive to Spartanburg (443 miles each way) for the M5 driving experience (AWESOME by the way) and I can tell you that the Water Wetter has allowed the engine to run about 20 degrees F cooler. That was with taking off 12oz of the regular antifreeze solution and replacing it with one bottle of Water Wetter.

Me thinks I like!!!
