Any idea what the recommended time/mileage is for the V belt to be changed on a CLK270 CDi...

Best to go by a visual check during service, you should be advised if its needed, I'm not sure if there is a service schedule for aux belts.

Yeah it was checked visually and looks ok just though they may have a 10yr sell by date or something..

Sounds like you need a bit of peace o'mind medication there. 'Appen buy one and put it in the boot as a spare and then have it changed at your next service interval as preventative maintenance. Both my cars carry spare V Belts - just in case.

Exactly what I've just done. Mine is starting to look tired, so I now have one in my boot from ECP (£15). If it fails the moblio mechanic can fit it for me!

That's exactly what Olly PCS advised when I asked him about this.

I usually put a new one at my leisure and keep the old one with the car, not that I've ever needed it. Got to be easier than doing it at the roadside.

Carrying a spare saved me on a cold wet evening in cardiff a few years back. Was just starting my 2 hour journey home when I accelerayed onto the M4 and snap I lost the belt.
Luckily I had a spare and they are easy to fit on the smaller cdis so I thought no problem ill have it on in a couple of minutes...a 320 cdi engine is too long in the 210 engine bay!!! Nightmare to do with no torch. Still, I got it on with some bleeding knuckles and drove home. All for the sake of a tenner (ish).

Some years back I was driving a borrowed Granada when I felt burning smell in the cabin.
Stopped and opened the bonnet, and the belt driving the aircon compressor was smoldering and bellowing thick black smoke. The compressor pulley had seized and the belt was rubbing against shiny metal.
I poured on the belt the contents of a bottle of coke I had in the car, to little effect - burning rubber can be difficult to extinguish.
Worried that the car will catch fire, I cut the belt with a Leatherman (time consuming) and threw it away - safely - then drove off.
The funny thing was the the car's owner was very unhappy when I told him I had to cut the belt.

Don't do him a favour again then.

I'm not so sure about that, actually. The tensioner has a 17mm 12-point nut on it, that a standard 17mm socket fits. I haven't tried it, but it seems likely that the wheel-brace would do the job. There's certainly room for it on my E220CDI (OM646, same as OM611 down there). Once you have too many cylinders (OM612 270, OM613 320) you may not be able to get to it so easily.
The only other tool you need (not strictly necessary but makes the job easier) is a pin of approx 4mm diameter to hold the tensioner "open".

Or you can pull it on by hand without any tools.
Not every engine is possible but most cdi engines are very easy to wrap around and then just pull up onto the water pump pulley.

I replaced the belt on my S211 320CDI a little while ago and removing the radiator electric fan assembly which is more awkward than difficult made the job very easy.

Strangely enough I changed mine on Saturday on my S320 CDI which is a V6 engine.
I never had to remove the radiator fan or cowling, plenty of room. Is yours the straight 6 engine?

Yes, mines the straight 6 lump.
