1996 XJ6 4.0,
I pulled her into the garage and smelled coolant.
After some sniffing around I found a trail of coolant coming from the bottom of the water pump.

I just put this water pump on & all new coolant hoses when I changed my head gasket, so this pump doesn't even have 5k miles on it yet!
Usually when I encounter an issue like this, I assume the pump needs to be replaced. But, given it's recent replacement, is there anything else it could be?
Bad gasket? Installation error?
I torqued that bottom bolt down some more in hopes that maybe I didn't tighten it enough during installation, and I'll see if it leaks anymore.

as a follow-up,
I took the pump off, fitted it with new grey RTV silicone for a gasket, and reassembled.
reassembly was such a fight, that I'd bet money I messed up how it seated.
the leak has been reduced to a mere drip every few days.
so better, but not completely fixed.
I'm thinking I'll just live with it and add coolant every few months
