You will be drilling a few holes... and may need a hole saw to run hoses to/from the heat exchanger. It's just nuts, bolts, screws, and hose clamps.
Keep in mind that you will need to be able to change the zinc each year and in time, the hoses. You may need to be creative when it comes to running the hoses.
I saved a wasting-away engine by instaling a fresh water system.
