Hello, I decided to write this as yesterday I tackled the dreaded oil cooler on my C320 cdi. To start off, I will say that it is an absolute pig of a job. Especially if, like me, you get it apart finally and see signs of someone else having tried to tackle it beforehand. I had a snapped exhaust bolt and several pieces of broken plastic and small screws lying around the old cooler in the 'V'. It took me from 9 in the morning till around 7.15 p.m. to get the job done and when she coughed back into life it was a big relief. I didn't get many photos as my phone died on me (its a fairly old model) and I was covered in oil and antifreeze so everything was slipping out of my hands. I will run through a bit more later and try to upload the images I have taken too.
