You won't be able to reasonably determine the amount of undrained water. So ascertain the total system capacity, the add straight coolant to achieve the desired ratio, then top with water. For example, your system capacity is 15 qts and you want a 60% coolant/water ratio. Add 9 qts of coolant, then fill the rest of the way with water.

I'll have to see if I can find the total capacity for certain...

I am guessing I need about two gallon jugs of G-05 (8 quarts) to get started with. I would imagine it will retain half the volume with water just by draining the Coolant recovery tank and radiator each time and what might come out the hoses too don't you think? If thats correct then I will be hard pressed to get to far from 50:50 by just adding coolant alone if it retains half water...

Oh I'm open minded, are you? If you have the facts, that all of the Mercedes parts are the same as all other manufacturers', you win. If not, and I have a book in my bookcase that I reference regarding the compatibility of each plastic and alloy, rubber, and metal part to different pH, solvents, etc., plastic is not plastic, cast aluminum is not just cast aluminum (there are some alloys common in Germany that we don't use here for castings for example), they're all different.

To be "open minded" is a good goal, once you are able to amass the facts necessary to drive a change that's great, but until the facts are known about compatibilty of other fluids, it doesn't seem prudent to change. This is especially true IMO when the correct and tested compatible fluids are available at your neighborhood NAPA and Autozone.

According to the 617 engine manual, your coolant capacity (including the heater) is 11 liters. So 1.5 gallons of coolant should be a good target.

Thanks tango.

Babymog, what are you all on about? Not getting why or where your wanting to argue about. No ones advising or even suggesting changing anything. Just laying some historic background of coolants in Diesels is all. And why they evolved... and why people cannot simply state that Green coolant is bad for a Mercedes Deisel without knowing that Green coolant does not tell you a darn thing about what type coolant it really is that was died Green. Thats the point. No need to try and twist it into something else is there? I could simply go buy some John Deere HOAT and be running the darn same thing as Mercedes wants you to and it would be Green. Zerex makes its G-05 specifically for John Deere and dyes theirs Green. Same stuff! See?

Remember when the really old stuff, the High Silicate stuff was Green too? Still is Green... the low Silicate got Green Dye and some of it got Yellow Dye when it got developed. Same stuff though. Then we had HOAT get Yellow and some even got Green. No industry standard to the Dye. But all the same stuff.

I think your missing the point I was trying to get across.

We all agree that you should use a HOAT (at least 84 and up) in them. No matter what color dye it is. And particularly if we don't we better know what we are using and make sure it has what it needs to do the job. But... it can be done. With the right stuff. Not worth bothering though is it?

This is exactly why I always stay out of these discussions. Someone wants to get personal about a simple thing like this. I should have just let it keep going along like it was and kept my mouth shut. I regret even trying now. So from now on just keep thinking what you want about Green Coolant. I don't care.

Just for the sake of concluding and important post ,there is a somewhat credible quote I found... sorry it is a repeat.

"NO! It cannot be used in ANY car. Jaguar, BMW, Honda........& alot of others cannot use it. Prestone was sued & supposed to change their "labeling" because the "Complete" coolant is deceiving to unsuspecting consumers.
Don't mix "GO-5" (thats what your Mustang takes) & "conventional" coolant, you will have "gunk" issues, that is correct. ONLY USE "GO-5" Coolant/Antifreeze in your mustang. You can use that Prestone "Complete" stuff if you'd like without any repurcussions but I never would. In fact I try to get people with "Dex-Cool" to swith to GO-5 when they are in need of a flush, either because it's time or because they had to put in a new Water Pump because the Dex-Cool caused it to go bad.
PS-you don't have to use Motorcraft (don't let the dealer tell you that you have to for warranty issues) but you do need to use GO-5. ANY name brand GO-5 Coolant/Anti-freeze is ok. Be very careful to buy straight coolant & mix it 50/50 with distilled water yourself!
