just so u know water pumps will piss you off!  Dont get a re-maned one get new!  I can also get a killer deal on parts,but i'd have to ship it lol.  I just did a water pump on the RV and it took about a day and a half.  Not sure what all u got to take off on the yota,but i bet there is a ton of stuff in the way.  Good luck!
