2011 radiator replacement
Have w204 that was in a small accident. Decided to try to repair myself. Seems the only functional problem is a punctured radiator. This model has what I believe is the combined transmission fluid cooler. However, I’m unclear how those connectors work. I’ve found a couple videos online but they skip over that step, one saying there’s a difficult circlip and another saying just unscrew the large bolts. I’ve been to a junkyard to try to see if I could understand how they come off but all I saw there were already removed yet the large bolts were still attached. I have everything else taken apart but I want to get these connectors right cause the transmission in these cars is pretty key.
does anyone have suggestions on how to properly remove these?
thank you in advance.












Heres how I found those instructions:

The highlighted in red seems to be instructions for removing the lines:
Finally how to disconnect the lines from the radiator:

Does it go past 2013? That's all that shows on my phone right now.
Thank you once again

My radiator was leaking, so I bought a Nissens replacement, it's exactly the same size as the original.
The old one came out, although it was extremely tight with only just enough room to slide it up and out.
Now, despite trying for 2 hours, I can't get the new one to slide it, there's just not enough clearance at the sides. I see from these fitting notes that there is minimal clearance between left hand side power steering cooler lines, but I can't seem to move them enough to let the radiator slide in.
Is it just me ? Any ideas ?
