Well, I installed the new radiator today. Man, that old one was dirty!

Putting the auxiliary transcooler on the new one felt a little strange, because a few holes have to be punctured in the fins.

When putting the screws for the fan frames into the radiator, they did not go in all the way. I didn't have any washers available, so I thought that I could get away with putting them in as far as I felt safe with. That worked on the first one, but on the second one the head broke off. The screw is still sticking out by a few millimeters, and I can just barely get hold of it with some pliers. However, I cannot loosen it with them. The pliers just spin, not the screw.

A trick that my Dad and I would use on stuff like that starts with a trusty old Dremel. We would use a cutting disc to put a slot in the end of a broken screw, and therefore simply turn it into a new screw. Stick a slotted screwdriver in the newly cut slot, and you're good to go. Unfortunately, I do not have a Dremel.

The fan is temporarily attached at that corner with a zip-tie.

Drives great. Stays at the correct temperature, and, of course, doesn't leak.
