o2 dodge ram 1500, does not get hot, no head gasket problem, yet it blows the heater core (replaced 3 times since november). has new radiator, new thermostat, no coolant leaks, no kinks in the hoses. i'm fair with cars but this is really kicking me.... anybody outhere ever had this problem?
someone mentioned a bad chassis ground, is there truth to this?


please help!! thank you!!
