You may also need to replace a couple of the capture nuts so pick up a pack or two of them while you are out, both sizes, the fan shroud uses them too. As for the hoses, just get them from the dealer, they will have a new spring in the lower hose all ready to go and used distilled water to do the coolant mix. I would suggest you do a 7 hour flush before changing everything out AND I would do the Tstat at the same time. Actually I'd do the all the hoses, belt, tstat, pressure cap and any idler pulleys all in one shot seeing as how you will have it all apart. If it has high mileage I'd also do the water pump too, again you will have it all open so why not. Don't use a rebuilt pump either, spring for the extra 10 bucks for a new one. I've had good luck with car quest parts, bad luck with the super mart brands from AA and such.
