How big a job is it to change alternator on bmw e53 4.8,and what would you pay for garage to sort as don't think I would have any knuckles left if I have a crack at it.

Morning Jerry

If memory serves not to bad a job on the 4.8 as the alternator is "normal" early 4.4 and 4.6 have water cooled ones which makes them a faddle to change/service. Have a check on www.realoem.com to make sure which alternator type. I would also check youtube for any video how too's then make a decision whether to sacrifice some skin or beer tokens to get the job done.

Good Luck
