peril 787b 0 Report post Posted June 20, 2009 Hey all, just wondering if there are any tips and tricks to replacing the main serpentine p/s, alt, waterpump belt on an M50B25 e34 525i? Am also going to do the a/c belt since I'm in there anyway and have to take it off first. I've had a look and it doesn't look that tough, but I've been caught out before with the e34 when there seems to be a "special order" of doing things to make the job take a quarter of the time.
