I went back and talked to the new Part Manager at my local Nissan.
Explained how we have bought numerous cars from the dealership over the years and how they always gave me discounts on parts. He said that he would always give me 20% off going forward, so that sounded good to me.
Really only get filters and belts from them for the most part.
As for changing the serpentine belt, was a minor pain. None of my 1/2 inch breaker bars or 1/2 ratchets would fit in the space.....without forcing the fan assembly back a bit. Otherwise, EZ.
So, on my list of tools to get is the serpentine belt tool....NAPA has a complete set for 40ish, but I only need the 1/2 inch so might check EBAY.
