OK, I have a rant on this site about my truck for other reasons..........

Thia is not a rant, but a lesson on how to fix this issue.........I replaced a leaking heater core last November..........I was never satisfied with the heat coming out, i tried a new thermostat, ran a Chevy 200 degree thermostat in it, boarded p the rad, kept the antifreeze full...........nothing got me above luke warm, well after talking to a very good friend that is a dealership tech, he suggested that the parts house heater core i bought was probably plugged...........he explained, that alot of the cores are now imported(read that Chinese, Taiwanese) and they solder them and the solder migrates too far in and plugs the core, basically the water flows through the top tank and bypasses the core itself, you get a little heat through radiant heat inthe metal but not actual coolant flow through it ...........I took it out and it was thoroughly blocked.......I purchased a brand new unit, tested it in the kitchen sink, ./by running really hot water and holing the core flat, you can feel the lower tank warm up as the fluid hits it..........I re installed it..........I CAN DO THIS WITH OUT COMPLETELY REMOVING THE DASH OR HEATER BOX. i CHEATED AND CUT AN ACCESS PANEL OUT OF THE HEATER BOX, INCLUDING SEVERAL FACTORY SCREWS SO WHEN I WAS DONE , I COULD REASSEMBLE THE HEATER BOX TRAP DOOR I MADE AND UTILIZE THE HEATER CASE SCREWS TO HOLD IT TOGETHER, i USE A LITTLE SILICONE ON THE SEAM TO AIR TIGHT IT AND IT WORKS AWESOME, 2 HOURS TO INSTALL A NEW HEATER CORE AND HALF THE WORK.............OK, so i reinstalled the core, buttoned up the dash and filled up the coolant.............I ran the truck up to temp, topped of the coolant, took it for a spin, stilll kinda luke warm............temp was right up where it should be,.wtf!!! Then i REMEMBERED, I used to hang with a guy who was a head mechanic at safro Toyota in Brookfield Wisconsin, we had a modified 4x4 truck it had bad heat and he had a tool he made from a rad pressure tester , he made a stand pipe that connected to the upper radiator cap housing. just like a cap would attach, filled it up, it was a 2 inch pvc pipe that was about 16 nches tall............we filled it to the top and lo and behold, more air burped out of th esystem, so i did the same thing except on the cheap. i duck taped a tall skinny funnel to the rad, filled it 3/4 full ran the engine and it burped up a bunch of air, i grasped th erad and heater hoses and squeezed them a little to aid it along, now I have intense heat , like when that truck was new..............so I don't believe it is a sdodge issue, but it may help you get heat this winter........good luck!!!

The heat in this vehicle has been low for years. Dodge has no fix for the problem. Driving speed produces warmer temps from the system, idling the temp goes down significantly. Changed radiator cap and thermostat, flushed core and replaced anti freeze. Nothing has helped.

Update from Mar 29, 2013: Still having same problem at 130,000 miles

Terrible feeling driving this vehicle in the winter with no heat. Really cuts the trade in value. WE are feeling really bad about this truck.
