2011 DR650se oil cooler

Hi I have a dr 650 that I owned from new. Recently a friend was in a bit of a pickle so I lent him the big girl. He tried to ride up a sidewalk but didnt think and tried doing it at an angle. Thus the first thing to hit the ground was his face and my  beloved DR shortly after. Now the oil cooler leaks a lot Nd while he is paying I wpuld like to ask of there are cheaper alternatives available.

Thanks for any input. And yes I know its never wise to lend your bike to a friend.
