2018 5.7 Hemi water pump replacement

I have a 2018 Jeep Grand Cherokee with a 5.7 Hemi. It needs a water pump.

What all have you guys done with these when you build em?

Factory OEM parts or should I go to Napa and get one?

I don’t really know what I’m in for as far as replacement, probably a pain in the *** to get to, I don’t know, haven’t looked too far into it because I was waiting on the dealer to get back to me as far as warranty. But I found out it expired and they want $900 to replace it. I’ll do it myself.
