    Some dodges (don't know what year) had a heater door flapper failure design where the door in the heater control box doesn't go the right way, and prevents heat from coming in the cab.

    Google it you will find your answer

    You know that this is based upon the fact that you've already determined the engine is really at temp, but the interior of the truck isn't.

    meaning like the gauge is staying in the low temp range? like the heater hoses aren't getting hot?

    I'd start to see if the top radiator hose gets hot.If it doesn't you have T stat issues,doesn't matter that you just changed it.Was it one of those gimmicky fail safe ones or possibly installed backwards or maybe just a bad one?If you had heat before,that's where I'd go.Also check your radiator cap that it's pressurizing.

    How long did you bled the system? Did the tstat open before you put the cap back on?

    In my Yota, the heater hoses are physically "higher" than the radiator cap. With that, I bought one of those "flush and fill" kits which has a Tee in it with a screw on cap. I installed it in the hose closest to the sky.

    You take the cap off during filling, and wallah... no more air pockets.







    Dont forget to put the cap back on, otherwise you get AF all over your windshield....





    Not like I did that 2 times, or anything:blush2:

    While in college, I replaced my bicycle that I used to get to class with a crappy $500 buick regal that I bought from a farmer near the school. I drove the car for 4 years with no heat or no air. Don't know how I did it, but I survived wearing layers and using lots of wiper fluid with deicer added to it in the winter and no shirt in the summer heat. Had no money. Upgraded to $800 plymouth sundance during grad school. Ordered a 99' ls1 z28 upon graduation. Can't get rid of her. Still in the garage.

    My point is........ there is no point :)
