Each dealer has a different set of included services for their 90k service. Call the local dealers to compare prices and what comes with each package. Dealer is always going to be more expensive than an local shop.
I called a couple dealers in the area and got a variety of options for what was included in a 90k service. With the multiple options came multiple prices. Ranging from 1k - 2k. The water pump I was told is a "lifetime warranty" product and doesnt ever need to be replaced. Glad they have faith but running another 100k miles on anything is quite a reach, I would think that would require the part to be replaced.
Good luck with the service.
thanks time to bite the bullet :(
