Nope, not all of the steps apply. I didn't have to remove my air box nor the expansion tank. I'm guessing he did to get plenty of room in there...I'm not sure if our trucks simply have more room under the hood but I had no problems leaving those in.

I replaced all hoses and the thermostat, but not the belts since they were recently changed about 10k miles ago when the alternator crapped out. But I would definitely change as much as you can and inspect everything for any worn out components while everything is dismantled.

My water pump is a Graf that I purchased from PelicanParts.com, which I'm very satisfied with! And it took roughly 2.5-3 hours, working at it on and off.

Good luck and let us know how it worked out for you!
