:confused: OK well I have recently been having problems with the cooling system as I have changed the water pump and the thermostat.. now when it overheats it starts to leak from where the thermostat is located anyone know the problem?. oh and from a 1994 jeep grand cherokee ltd. 4.0l -6cylinders.any suggestions would be great!

Did you install the thermostat properly? Improper installation is a common cause of engines overheating.
