The squeak is probably a belt, probably the genorator belt, as the tension has to be manually adjusted. and it's in a tight spot. The other belt is on it's own spring-loaded tensioner. You were due for a battery anyway, but still you have to wonder it your battery problems were caused by a loose belt.

To be upfront, I'm not a fan of Goodyear places, I won't use their tires anymore (tread seperation all the time) and the last time I was there to fix a flat, they left 50lbs of pressure in the tire. With that in mind.....

Any good menchanic doing this job would recommend doing the timing belt at the same time as the water pump. Why? because to do the water pump you must remove the timing belt. You're already paying for the labor, but when re-assembling, he just reachs for the new timing belt instead of the old one. If you have normal mileage on a 2003, you probably aren't that far away from needing a timing belt change anyway.

At this point, I would seriously think of changing the shop, maybe even going to a dealer, they're expensive, but you would hope they would actually know how to fix their product.

Good Luck!
