Replacing coolant hose
 

I have an '03 Jetta GLI with the VR6 engine and it just recently started to leak coolant. I looked at it today and it appears to be coming from a hose that goes from the oil cooler to the engine. The problem is I have no idea how you would go about replacing this. Has anyone ever done this or have a DIY possibly? I really don't want to bring it to a shop but I don't have any idea how I could replace it due to where it is located.
