I use my dads tools and if he doesnt have it I steal my brothers, I have my own basic stuff and keep it stuffed under my back seat, and its easy working on these things just got to learn the basics and you can do alot.

The water pump is a really straight forward job that requires basic tools and a little bit of time 4 hours if your doing it for the first time, 2 if you've done it a couple times, a good starting point for working on our trucks
