I have the same problem, in my research I've come across several reports that a clogged catalytic converter was the problem. If you haven't cured the overheating problem you might want to have it checked.

I had the same problem, did the same things. If I run the heater, it cools. Once it cools, it usually does not overheat again. It got to be almost undriveable. I did one thing at a time, fan clutch last cause it only overheats on the highway. Which is opposite of what it should do. Fan clutch did it for the year....now overheating again. I'm doing the fan clutch thing again.

I think everyone that has a simular truck has the same problem. I feel that it is a design problem. I am going to add a pusher fan to the front of my truck and see if it will increase the air flow. I tried to find a bigger radiator but no one seems to make a replacement because of the way it is made to hold the trans cooler ect. My next move is to add a small radiator with a fan somewhere on the firewall or behind the grill. This is kind of drastic but I am almost at my wits end.

i had the same problem when towing my camper with my dakota with same engine.it ended up being a head gasket leak. i think you can do a pressure test at a garage to see if you have a gasket leak.

it's the head gasket..sad but true! I'm doing the head gasket job right now actually. Just to make sure though..check your oil first..as in drain it..there may be water in your oil..also can check the spark plugs. Preferably number 1 first. Hope that helps ya.

hi, i had same problem, hotter on run, now ive cooked it, never replaced rsd cap correctly after checking on motorway( yep im in uk)now have water coming out of muffler box tail pies and oil fill cap,,, head casket most definately gone,,,,like yourself can fix headcasket(S) but the problem that caused this failure is still there, so im opting for replacment engine... and taking risk of it being sent to uk from usa,, so even a gauranteed engine would be crazy cant send it back ups and after fitting labour could be complete waiste of mony,,, so dont think you have it so bad theres always me,, im so unlucky if i tread in dog poo there be a nail in it,,, good luck to you all

Have 2002 Ram w/4.7L... Found out the secret from a disgruntled Dodge mech. The head bolts are faulty and stretch after repeated heat. This allows certain parts of heads to warp. THIS allows water to be sucked through engine and burned. Slow process but will cause engine to over heat. Also oil is slowly pulled same way. Having unusual coolant or oil loss??? Now you know. My 2002 just blew due to over heating and I've been fighting Chrysler 2 years over the problem... and their CEO wonders why there is a consumer fear of their products..... DUH Great truck....bad engine. Can't afford replacement. Chrysler should invest AD money in cust. satisfaction.

Hi everybody !!! I have found the problem . 2005 4.7 Magnum - All parts changed,waterpump,T-stat , temp sens ,fanclutch .?? Still overheating ?? This solved it . 5/16 allen wrench . Follow top rad hose to the engine see the allen screw ? Loosen it to bleed air from cooling system ,have engine running until only coolant comes out no bubbles !! WORKED ON MY TRUCK !!
