4.2 V8 Serpentine / Alternator Belt
 

Hi There,

Just fitting a new coolant tank and then re-fitting the under tray after draining and i was looking if you could access the front parking sensors easily (you can't) and notice that my belt has a slit it it. It's reasonably small atm and along the belt ( if it goes i'd have two belts about 1/3 and 2/3 width).

At first it was a minor panic as I was worried it was the timing belt, but it it isn't and that's a toothed belt which makes far more sense.

However i'm now researching how to replace as loosing things like the alternator and power steering would be a royal pain etc.

Anyone know much??? I'd prefer not to have to take the front end off for example.

Did one on my jeep with a bit of swearing and wiggling of things, though that had a little more space and less AUDI ideas of lets take the whole car apart for an o-ring and charge the customer thousands :-(

Ta,
Lee

It can be done from above without removing the front end.

The part number of the belt is 077903137AE. You should be able to find one for around £20.

Ah....I did see that, thanks!

Also got the PDF GR13 (8 Cyl engine mechanics) pages 53 & 54 which detail the official way to do it. They mention a locking pin T10060 that can be put in the idler to lock it open one moved with a 19mm socket. Am guessing a drill bit/nail etc will also do the job!

They mention removal of a few things, like the lights and stuff, but that seems general bits and only the under tray seems actually useful!

Now to find the belt for the BFM 4.2 2005 engine +++
