Question '03 Water pump and CP3

I need to replace the water pump as it is leaking. I also need to replace the CP3 in the near future. Would it be easier to do them both at the same time? I don't know how much of the disassembly operations overlap each other.

If you have a way to pull the cab I'd do that and do both at the same time and be done with it

No need to pull the cab for ether job but it probably would be easier to do them at the same time though because some of the same parts have to come off
