How do you change an alternator on a Mercedes sprinter?

Answer 1

first you must disconnect the battery then slacken the fan belt ,there is a13mm nut and bolt at the top of the tensioner that must be undone then place a large screwdriver in the hole and press until you can remove the long bolt and release the pressure slowly.note which way the belt goes just in case it comes off,or you need to take it of a pulley to get extra slack. then you need to get under the van (ramps might help) take off the under engine cover if fitted 2 * 10mm nuts and there will be the alternator to remove the nuts you will need the star shaped sockets and a ratchet with a small extension not sure of the size of the bolts,remove bolts 2 or 4 depending on model of van and wiring to rear of alternator try to get enough slack on the belt and the give it a pull and a wiggle and with a bit of luck it should come free, a bar may be needed if stubborn. then replace alternator and put back in reverse order bit fiddley to get the higher bolt in had to do this from top then tighten from bottom(small hands also help) took about 1 and a half hours when I did my 1999 sprinter anyway good luck!!!!!!!!!
