I'm a been a happy owner of a 2008, 2500 Dodge sprinter, purchased used in 2015, and I've learned a lot from folks on this forum over the years. My rig has 146,000 adventure-seeking miles on it. Now I need to ask advice, please. During an inspection (at time of oil change) it was noted that my alternator pulley was seized and needs replacement. I've been really happy with my regular mechanic, but because this came with a long list of other items that added up to mucho dinero, I decided to shop around. The second shop I went to said replacement was necessary and also recommended I replace the alternator and the serpentine belt at the same time, preventatively and to save $$ in the future since they'd already be removing the serpentine belt and because its the original alternator. He said I was on borrowed time with the existing alternator. Any advice on this? Should I go ahead and replace the alternator along with the pulley? Should I replace the serpentine belt as well? Thanks in advance for your advice!
