How can I replace the radiator in my Audi 80?

I noticed a leak in my Audi 80's radiator and I want to replace it myself. What steps do I need to follow and what tools do I need for this task?

First, start by draining the coolant from the radiator using a drain pan. Then, remove any components that may be blocking access to the radiator, such as the fan or shroud. Next, disconnect the hoses and remove the old radiator. Make sure to clean any debris from the mounting brackets before installing the new radiator. Finally, reattach all components and refill the radiator with coolant.
