    Contrary to what has been said, the valve can get clogged and reduce the water flow to near nothing. The po of my truch didn't do much in the way of prevent maintenace. I pulled the valve and it was gunked up. It only takes a few minutes. I'd check it along with all the other recommendations.

        After my very uneventful flush of the eater matrix this past weekend I can this morning to a little coolant puddle under the rear of the front wing..
        Seems as if I may have ruptured the heater matrix during the endeavor..
        Looks like I will be swapping it out for the GDI unit after all.. still no appreciable difference in heat, so it will be in conjunction with a new thermostat and another flush..
        The upper bolts for the heater matrix, are they only accessible by removing the dash? Green bible says something about a trim board.. I removed something on the dash, but did not see anything behind it..
