On my way home tonight my 2001 E320 cdi estate started to overheat, lost power and the steering became very heavy. The battery/Alternator indicator also came on. Pulled over straight away (in the rain on the M56!) and Mr RAC diagnosed a snapped fan belt and I was towed home.

I'm assuming this is a fairly straightforward thing to fix. I have a good indie nearby. Also assuming that that the other symptoms are as a result of the fan belt snapping. However, I would appreciate any advice or other issues to consider.

Mr RAC seemed to think everything else looked ok on his fairly cursory inspection (even used my favourite MB-related phrase 'bombproof' when talking about the engine!). It's an otherwise reliable motor and it all looks pretty clean under the bonnet. But I have an untrained eye so I'd appreciate any additional comments from the much more experienced and knowledgable members of the forum.

Changing the poly-belt isn't difficult and shouldn't cost more than £100 including parts and labour.

Do check the condition of the idler and alternator pulley, the alternator pulley has a clutch, these fail shredding the belt.

Yes - you have to ask why the belt snapped. I'd suspect there is a problem somewhere

When the V-belt went on my old E430 I found it to have been caused by the idler pulley failing - I found it lying on the engine under tray!

Very hard to put a new one on without that ;):D

The idler pulley was the cause of the belt shredding on my LWB Sprinter.
The 10 miles drive home without power steering was great fun, especially at mini-roundabouts which took 3-4 attempts to turn right at.

I had a high-pitched whine from the engine that followed the rev pattern and it was cured when I fitted the new pulley.
The noise had been there for well over a year and I just couldn't fathom where it was coming from. :confused: :rolleyes:

Thanks for all the advice. Looks like an old belt but going in tomorrow morning to a local independent. £60 to replace the belt. I'll have him check the integrity of the alternator pulley too
