    Some of the 3.1 liter engines leak coolant from their Intake Manifold Gaskets, be sure to check for that. Also do a pressure test of the whole system to see all the places where it may leak.

    you could get some dye and add to the cooling system and let it run and watch where the dye or leak is coming from. it will turn floresent green in color.
