At 75k miles my Serpentine belt has some minor cracking and I am thinking of replacing it. My dealer wants almost $350 for only a belt change...says the new belt is $120.00 and about 2+ hours labor to do the work. Seems a bit steep to me. My local parts store has a new Gates belt for about $65.00. Has anyone recently had a dealer replace the belt...what was the cost? Can someone write some DIY instructions with a belt routing diagram, how to access the tensioner, etc? Photos would be nice! There is nothing about the belt posted in the DIY stickies. Seems like a fairly easy job, but given the tight quarters of the engine compartment it would be nice to know a step by step procedure.
