Do you want to remove the pump, or the gearbox?

The pump. What tools do I need please?

it's a little different for the different engines.

what size V8 do you have?

and do you have a C1500 or 2500?

It is a 5.7....and it is a C1500.

Install in reverse procedure.
Use pulley installer to install pulley, (same deal with renting one from the parts store)

they both have a very convoluted bleeding procedure. and I will type it all out if you want, but that's not how i do it.

I jack the front end up, so the wheels are not on the ground.
Start truck and turns wheels very slowly, back and forth from lock to lock about 10 times. just barely tap the lock each way, DO NOT hold it there.

let me know if you want the long version.
