It is pretty straight forward, the main thing I suggest is not to use a impact on the pump mounting bolts. They tend to corrode inside the front cover and you need to be able to feel them by hand as to not snap them off. mm
The only other thing I would suggest would be to put some silicone on the bolts when you reinstall them to make sure the coolant doesn't corrode them more and also seal the coolant into the block. I always do this.
Of course if your timing chain is loose your half way there!!! I also replaced my water pump bolts with stainless ones from the local hardware store.
