Look around for some more for threads addressing this issue. You've gone about the very hard way. You CAN repair just the leaks at the radiator end. There are several threads from a couple of years ago about cutting the tubes so that you can use compression fittings on them and insert a much longer rubber hose portion and then new connectors on the end of the hose so there's more flex available and you won't get another leak. Search for my thread and another on this topic. Fix it right in the spring.

It's not that bad fixing the front connectors. If it's also leaking in the rear then your s*** out of luck I'm afraid. This repair will make it better than the originals.

Calgary, OMFG too damn cold there now. I've been there several times in the winter.

Good luck.
