I bought the felpro O rings from advanced auto. I heard felpro is a decent brand so they should hold up for a while.

I guess I'll be getting the clips from the dealership because there aren't any part stores that sell them. I'll probably have them install the clips too because they such a pain to install. Is there a special tool I can buy that will make this easier?

 

Try a junkyard for the clips. Chances are good they are across the spectrum on other makes/models. They just snap into place.

 

The dealership had the clips for 65 cents each, so I figured it wasn't really worth it to go to the junkyard.

I once again found that I should take advice from forum members when I'm given it. I remember a bunch of people telling me that I should replace the bypass hose while I have everything out of the way, but I ignored them. 2 days after getting my truck back on the road, I sprung a massive coolant leak and traced it back to the bypass hose. It actually split in half lengthwise! Anyway, live and learn I guess! Thanks again everyone for your help, my truck's never run better and I've gained 3mpg!

 

Good to hear, and always remember that unless you know how old certain hoses are, preventative maintenance never hurts
