Now that I have put on my flak vest and helmet, let me ask you the question that ALMOST ALWAYS results in a red flaming folder. Are you using the proper Mercedes antifreeze?
If you put green coolant/antifreeze in your car, you should drain it as soon as humanly possible, flush the cooling system with Mercedes citrus cooling system flush, part number 000-989-10-25 (I don't have a price for you, but it's usually around $11.00) and replace the antifreeze with Mercedes antifreeze, Part Number Q 1 03 0002. Fast Lane has it for $10.89 per gallon. You only need one.
Now some people will disagree with me, but I also suggest that you go to the local supermarket and purchase a gallon of distilled water like you would use in a steam iron. Mix the antifreeze with the distilled water 50/50. Or, you can go to a local Pep Boys, and buy a special de-ionized water for use in batteries and radiators that's made by Peak™. I really can't recommend that you use tap water.
If you want to know why I am suggesting all of this there are several lengthy threads on that subject that are already in the archives. This one links to all of the best ones:

And I don't know where you got the idea of putting vinegar in your cooling system, but it won't even do a 10th of the job that the Mercedes flush will. And vinegar is way too acidic, and you could actually harm your water pump seals by running it in your car for a period of time like four days.
