Oil cooler replacement

It appears like a stone has put a hole in one of my front oil coolers (driver side).
Does anyone who’s broke one before and have an idea of what cost a replacement is, or what size as I have a few spare in my garage off other cars?
Also do you think it’s going to be a PITA of a job to do, that will leave my driveway covered in oil; i.e. should I get someone else to do it?

edit: Or thinking about it maybe it’s just the from connection that i cant see gone loose. I suppose that’s a w/e spent removing the from clam to have a look just to put it back together then

Cheers,

Neil

Enjoy …I did it twice the other week

I haven’t got anywhere with it yet as the stupid locking wheel nut sheared off! My torque wrench is going straight in the bin lol.

Ouch!
