Oil cooler

I have a 2018 grand Cherokee 3.6L. It seems like the oil cooler is leaking as I’ve noticed some oil stains just under the housing. I’ve ordered the aluminum part as it appears like the oem is made out of plastic (thus why they crack and leak🙄) just waiting for the part to arrive. Any advice or tips on replacing it? It seems like it’s a bit of a pain in the butt to replace.
