Heater Control Valve
Looks like your heater control valve is leaking. Here's a replacement:

I agree. Bypass it. All it does is redirect coolant flow around the heater core when the heater is not in use, which IMHO just allows the trapped coolant to stagnate. Just bypass it and make sure you plug the little vacuum hose connected on top of it.

Just a FYI for the people thinking that the 98 doesn't have a control valve your wrong. It's under the dash near the heater core.
Now that I said that just get rid of it for the winter time. Now I sat that cause in summer you will have coolant pumping thru the core causing a already hot freakin day even worse in your xj.
Why not replace? There not expensive. $30 is the most expensive one I found. Takes 15 min to swap. Paying for the molded hoses to "bypass" it is probably gonna be the same cost.

On the positive side removing it should at least help cool the coolant...

Ok so I may be wrong on the 98 having it under the dash. Lol. It was a long day.
But also late Cherokees have a door that closes off the airflow to the core. Early ones don't.
