W204 C350 radiator change

W204 2012 C350 petrol with M276 NA engine.

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.

Is it just me ? Any ideas ?

In the end, I had to remove one of the power steering fluid cooler pipes in order to get the new radiator fitted. Incredibly tight fit.

Glad the clamp fix worked. That loose hose is a known weak point, especially after disturbing it during service. Your real-world fix is spot on.
