I've also heard that leaving the radiator cap slightly off will cut down
on leaks since the system can't build any pressure. That being said, without
pressure the fluid will boil faster. :/

Probably the plastic tanks have busted... On the passenger side at
the bottom of the radiator is a coupler that *might* be leaking, but
usually if as bad as you have the tanks have gone bye bye.

If you stuff it full and it really is only a coupla miles, you might
make it before the coolant level drops too much--by waiting until any
local traffic congestion is over. If it drops too fast tho, you could
risk worse than water pump damage. A tow truck is very likely
cheaper than the extra repair risk.

While replacing the radiator, probably a good idea to do the
thermostat at the same time. If there is much staining on the
water pump, consider replacing it as well while that mess is out
of there.

May also want to consider an aftermarket radiator if you have a good
Jeep shop to install it. Removing the radiator on the 4.0 ZJ is a
true PITA due to the shrouding, that is is plastic, and the A/C and
other junk in your way.

Or taking the thermostat out (Someone did that to my Waggy - and the old rad
blew in
three places 20 minutes after the new thermostat went in it !)
