If he doeasn't have to go home right away and can wait 24 hours, and the crack is within easy reach, you may want to try JB Weld for the ride home. It does take about 24 hours to cure. I know some pusirsts on here will poo-poo my suggestion, but I've used it to make some "temporary" repairs on a few radiators which ended up outlasting the cars themselves. I even used it once on my 94 Ford Escort with a leaking tranny pump cover with great success.

Of course there are risks, and the safest is to replace it as 911MMonty suggested, but if you're in a bind and can't do it right away it may be worth trying.

Good luck!
