I figured it out. While looking at used oil coolers on ebay, one for a 190D popped up, it is exactly backwards of mine, just like the one I received. The MB part# on mine is 2015018201. The MB part# for the 190D cooler is 2015018101 only 1 digit is different. It must have been misboxed at the factory.
All in all I just want my money back and I will try to find a used one and save some $$.
I have had a brain storm on the line set as well, if it works all the parts should be available at your local parts store. It may take me a few days to get it all figured out and put together then I will post back if it works.

I need a used cooler 1st and fast. Doesn't even matter if the threads are messed up on the connectors with my new idea. Gonna post a parts wanted thread see if I get any response.

Thanks.
