Leak from coolant tube - O-ring? How to replace?

[ryan1980]

Hello,
I have a leak which is coming from this coolant tube - its on the right hand side, near the exhaust . Im assuming there is an o-ring there which has gone (a part number would be great!) But more importantly, how do i access it to change it out? Does exhaust need to come off?

please see attached photo:)

Thanks!!

Hard to see in the pic, but if that is the tube that the radiator hose goes on then what you want is:
O-RING (18.3X2.3) (ARAI) 91301-147-023
