Hi All,

I have a 2012 C220 Diesel with 165k miles on the clock, I have the front end open, so radiator, intercooler, radiator fan and front bumper are all out.

Now that this gives me plenty of room to work - what should I replace while I am here? Everything on the car is still original, just normal servicing has been done.

They're all things that have failed and been replaced on mine

As CSJ says above, also new auxiliary/serpentine belt.

If you’ve had to take out air con - maybe a new dryer canister.

Give the cores on your rad etc a good visual check, wash, and a coat of black satin to help fend off corrosion?

Dab of copperslip on bolt thread when installing.

I guess oil cooler requires new engine oil too? Or can we do it without?

Ok guys, I have taken the cover off and can see some oil, now bear in mind this is a 165k mile engine with everything still original, seems like oil is leaking from somewhere? Is it anything I should be worried about?

Yes the leak needs attending to before it gets onto the serpentine belt and rubber hoses, I see the oil is migrating onto the pulleys already oil and serpentine belts are a no no

Far less than you’d think, and I bet your driving would calm down too- mine did on purchase of my V8!

Where could it be coming from? Oil cooler seal?
