Aux belt for Alternator, fan etc;

Hi all,

I am always aware of the problems of belts failing (timing, alternator, trousers etc;) and am quite religious in having them replaced at about 60,000 miles on all of my vehicles.

Having done a little research on my Mk6 Transit I am happy to find that its timing is by chain thus reducing the possibility of the catastrophic damage a broken belt could cause.

The potential for the aux belt failing, thus causing alternator, fan, water pump, power steering etc to cease functioning, niggles within me. Good practice seems to indicate that they shoud be replaced at around 60,000 miles or 6 years (more relevant on most motorhomes). My van has 23,000 miles on it and the belt looks like new. I am happy with its condition at present but Sods law says it will eventually fail somewhere in rural France at a weekend.

With this in mind I now carry a spare belt costing around £17 ex vat. together with written details of part number, engine number, length, no. of V ribs etc. The important part in the plan is that this info is recorded on the reverse of a laminated card showing the route that the belt needs to be placed over the pulleys. Better than trying to guess the route since the belt it will replace has probably broken and thus offer no clues as to the correct routing.



A bit of belts and braces, but keeps me happy.

Not a bad idea at all Davy.
I had ours replaced last year as it was 5 years old which I am told is another time to do it.

I replaced my serpentine belt last year as it appeared to be shiny and slipped and squeaked on cold start up. I also replaced a tensioning pulley as the bearings appeared to be on their way out. I kept the old belt incase of emergencies.
Last week a whistle developed and when I opened the bonnet I noticed the belt was slipping. I checked the alternator and the output was quite low. I removed the belt and alternator and discovered the bearing in the alternator to be knackered. Fortunately I had a brand new alternator I had previously bought for another Chevy that was a direct fit. This was duly replaced. Being the Easter hols, I fitted it with the old belt as the existing one had been slightly chewed with the intention of replacing it when motor factors reopened.
But I forgot and at the weekend I was heading to the Shepherds Rest and stopped to purchase some medicinal alcohol. When I returned to the van it started rather lazily. I popped the bonnet to discover the belt had jumped a tensioning pulley. I decided to drive to my mechanic but noticed that the engine temperature was rising as the water pump was no longer being spun.
I stopped at a nearby garage and borrowed a 16mm socket and rachet which enabled me to put the belt back on the tensioner. The mechanic let me keep the tools until my return but I didn't need them again. The old belt had stretched slightly.
Note to self GET a new belt today

It depends how long it has been squealing . If the belt has turned shiny on the driving side"V" it will need to be changed or if you have to tighten it too much to stop the squealing it will put a lot of extra pressure on the alternator bearings and that will cost a lot more than the belt to replace. :up:

I got a mechanic to do it but you can do it yourself some parts are a bit tricky to get at and take apart
