Replacement alternator belt at 58,000 miles

5 April 2015 - Filed under: Repairs + Servicing

Replacement alternator belt as MINI flagged it as starting to perish during the service. I had to remove quite a lot of car to get to it:

The old belt was certainly showing some signs of age:

North Oxford MINI quoted around £100 to perform the belt swap, this is seems quite reasonable. The OE part cost £26, I also had to buy a new tool – the belt tensioner can only be moved into the service position using the 12 point end of a 21mm spanner (my local Machine Mart provided one for £4). Given the amount of bits I had to remove to reach the belt it might have made sense to get the dealership to do it, but there is a certain satisfaction to doing these things yourself.

Associated TIS instructions:

Removing and installing/replacing front left or right wheel arch cover

    Just to say thanks for your posting. I followed your example and changed the belt myself, it took about 2.5 hours. The worst thing for me was removing the wheel arch fender and I had to replace 3 of the push-pin clips. I used an adjustable grip to turn the tensioner which worked fine, but I needed a helper to push the lock pin in position. Bit fiddly to get to the pull tag for the friction wheel, had to do it by feel only as I couldn’t even see it. Overall a bit fiddly in places, but actually get the belt off and a new on was quite quickly done and putting it back together was easier than taking it apart! Thanks again for the pdf diagrams, these were invaluable.
