i was just wondering why you have to take the harmonic balancer off to do this i am fixin to do one and i don't have the socket to remove it

There is a bolt behind the balancer to get the water pump housing off.

An awsum right up I am so not looking forward to doing this job, but after all the horror stories Ive gotten your right up makes it seem like a regular day at work. Long but not insurmountable. Thank you, now if I could ony find a way to get paid to work on my own truck.:humm:

Thank you for the time you took to do pics and write up. It's the first info I could find after looking for three days. I couldn't even find a book at the auto parts store, but they'll sell you a book at the dealer for about $225.00:bat: Anyway thanks again, big help. I'm not sure what nut is going to break first trying to get the balancer off:s:. P.S. I got a quote of $1,450.00 to do the job. "No way am I ever going to pay that to put a water pump on." Almost rethinking that decision!!! not.

:rocking: I finished the :argh: pump. Wow, what an ordeal to put a water pump on. Definitely easier on the older trucks and cars. I can hardly wait to fix something else. It is kind of fun to conquer the unknown:rocking:!!! I think if I had to do it again, I could easily get it done in half the time. And you guys who claim they got it done in three hours are full of bad stuff. The tech book estimates 8 to 9 hours. Anyway, Love my truck, it's awesome.:c:

Im glad i found this cause i have to attempt this tomorrow. now is there any other tricks/tips/mods that we should do or other things we should look for while everything is out of the way? Like signs of wear on (fill in the blank) etc..... thanks. I have to say this forum is the most helpful. And good write up.:c:

wear on the inside of the pump housing is normal

So would it be wise to change the thermostat in the mist of all this?
