I've not done it msyelf, but I think I saw a reference, once upon a time, where someone claimed to have repaired such a cooler by cutting the aluminum fittings off the cooler, drilling and tapping said cooler, and then installing steel fittings (after flushing out the chips from drilling and tapping).

OK, did a quick search, and I found it here. It's a post by Brian Kmetz.

I haven't tried this myself, and I don't know if it applies to your situation, but it might be worth a look.
