anyways, i cant figure out what goes in these two holes...

I found what I think might go there...

The bolt i put in the right hole has the smaller bolt inside of it jammed down tight to seal the hole. I checked my 4AG pdf manual and it shows a line going from the oil filter nozzle to that spot. Do I just block that hole like i have it in the second pic and use the nozzle by the oil filter to go to the oil cooler?
Thanks
