Afternoon all,

My first post and its a plea for help I'm afraid. My 2010 C250 Estate has a coolant leak that appeared from no where yesterday, after a big of digging around in the forums and on the car itself, I can say it is definitely not the water pump. After more digging around today, I found the leak on a pipe from across the top of the engine, that goes into the bulkhead which I assume for the heater system.
I've attached some pictures of where and what is leaking. I was wondering if anyone knows where i can get the part number from to order this bit. I've had a scout through google but to no avail at the moment.

Thanks in advance, Padge

Hi don't know if you are still active, but I was wondering did you get this fix had mine is leaking from the same spot.

Padge

Yeah I got a fix mate. This is the part number on the invoice I got. It's a bit of a pain for access but easy enough to change yourself

Adam Richards

Thanks for the quick reply, did you change it yourself then? If so any pointers

Padge

Yeah I did it myself. I think you just need pliers to get the clips off. The only major issue is access, but as long as your hand skills are OK you'll be fine. Aslo I'm quite short so had to pretty much lay across the engine 😂

Hi guys! I problem with leak in same spot too. Do you guys just replace the plastic "hose" or did you change rubber sealings in the female connections?

Never the first or the last of coolant leaks with these OM651's as both the water pump and fuel filter housing coolant inlet outlet have been redesigned .
