Dad died and left behind a 2005 E500 that had a minor front end accident several months before he died, it's been in storage for almost a year and we decided to restore it and keep it as a memory of him but need some insight for a few things.

Dad purchased most parts to repair it himself but after trying to install the radiator assembly and seeing some minor differences, we've found he accidentally bought a radiator + radiator fan for a W211 E350.

The radiator looks almost identical with the only differences I see is the transmission cooler lines are in the front instead of the back, and the radiator quick connect diameter is 1mm too small for the E500 radiator hoses. We have a solution to the cooler line problem and believe we can figure out the radiator hose situation pretty easily.

We have never owned a Mercedes before so have no idea where to look/search to find these answers. We have tried googling and searching through these forums to no avail.

My questions are:
1) Hose fitment aside, is there a significant reason not to use the E350 radiator? Is there something else I don't see that would hinder its ability to cool the E500?

2) I believe this happened after accident: Only passenger side window works with its window control. Drivers side window control doesn't work at all (any window, or window lock function). Rear windows also don't work. Does this sound like a fuse problem or something more serious? Where can I find electrical diagrams for W211?

3) Is there any online part diagrams where I can find part name and numbers for the W211? I'm in particular looking for either the name or the part number for the small brackets that bolt to the reinforcement bar and help mount the headlights.

Pic for reference but the equivalent for the E500 instead or if they're interchangeable let me know.

Thanks in advance!

 

There's 3 possibilities. First there's eBay where you can buy an EPC/WIS knock off DVD which will the parts and repair procedures for about $10.

Or you can sign up for Mercedes Epc-Net for about $75 for a year.

My advise is to buy proper radiator.
Mercedes can be pretty untollerant to any monkey jobs and likely 500 will generate more heat than 350.
Even if you live in cold climate, the fans will work more and burning more fuel as the result.
Windows sound more like fuse, but they do have electronic controls who can be a nightmare without SD computer to troubleshoot.

 

Use correct radiator. Get car running then get it to a shop that has a star diagnostic system .

 

First my condolences to you and your family. Get the small items completed, he'll be happy!
