will leak from a weep hole in bottom of pump, that is a vent for the seal. when the seal goes out, water will exit thru hole. If the engine ran hot, have them also instal new thermostat.
Being that ist either a 4.0 litre or maybe 3 litre v-6 labor for pump shoudl be around 2.5 hours. Depends on who does it, we get $65 an hour for labor. And yes stay away from Stop leak!!
