The multi cooler cools the air charge (after-cooler), engine oil and tranny oil.
Unfortunately I just deleted some photos a few days ago of one that I was selling for a friend.
Sounds like it is in fairly good shape if it comes apart. For tips on keeping it that way Tony Athens has an article on the boatdiesel website that might help you out.
I'm thinking you might have a good idea by re-plumbing it for antifreeze but you'll lose some power because you won't be cooling the air charge as much.
I think the engine oil and tranny oil would still get cooled adequately, but I would want to check it to make sure of that. A few experiments with an IR temp gun will tell you that.
You also might want to add a pyrometer to monitor EGT esp if you use any of the upper end of the HP range because the compressed air will be hotter. Black smoke will be a clue there.
