I own a 99 durango with a 5.2 with almost 103k. My heat is only luke warm. I changed the t-stat but no change.I also flushed the heater core and there doesn't seem to be any blockage. On the heater hoses under the hood the the one coming out by the t-stat is fairly warm but the one that goes back into the water pump is much cooler. Could this possibly be the water pump.
