98 Grand Caravan 3.3L Oil Cooler Leak

I discovered a pretty significant drip coming from what looks like the point between the oil cooler and the block. I understand there is an O ring between the parts. Anyone have any info about removing and installing the oil cooler as far as torque values, etc?

pretty easy job. replaced many of these. drain the oil and coolant. and there will be one big nut that holds the cooler on take that off and your golden and when installing it it will only go so tight it will not over tighten so you are also golden just go as tight as it will go
