95 Honda Civic Heater Core Problem..

Okay people this is the first time I've posted in this forum so I assume I'm in the right place.

My problem is that i have a heater core from a 1995 Honda Civic EX Coupe, and it has leaked all over the driver side area..

Note: this is only on the driver side only..

I would like to know how to..

inspect, replace and/or install - the heater core
I've looked online but not much has come up, all suggestions would be greatly appreciated.
