On the standard Mazda oil cooler there is a port next to and 90 degrees off from the port on the end of the cooler. What is this port for?  There is a large hex topped bolt in the hole.

Could I use this location to run a line to instead of the one on the end?  It would greatly clean up a plumbing issue I have as currently my the port on the end protrudes out of my cowl slightly. If I can use this other port I could likely eliminate adding a blister.

Thanks.
