#151 of 168 2000 Durango Overheating
Dec 19, 2011 (11:11 am)
">My 2000 Dodge Durango 4.7L V8 has been overheating. I replaced the thermostat when I was still living in Vegas, but am in Sacramento now, and seem to have a small leak. I've been adding coolant and/or water (alternating) once a week or so lately (only had to twice in the summer, so the leak seems to have increased). It's hard to tell where it's coming from from under the vehicle, but it seems to very possibly be coming from what I was told is the heater core, yet the pics of the part looks quite different in shape. Mine looks like a vertically long a slim radiator with an arched shaped tube coming off the top. It seems to have a small leak at the base of the tube if you look close from the top, when looking under the hood. I have a friend coming over to help me try to figure out what the problem could be today. Any ideas would be greatly appreciated. Thanks

I'm a little confused, you can't see the heater core under the hood, only the two pipes that come through the firewall and the hoses connect to. The heater hoses run right along the left (drivers side) cam cover from two metal pipes under the intake plenum back to the pipes coming off the core. If the core leaks it usually manifests itself by a sweet coolant smell coming from the heater of defrost vents, a small dripping under the right side front near the back of the engine bay (plenum drain) and a haze that may form on the windshield when the defroster is on. In extreme cases the carpet could be wet up under the dash below the heat/AC plenum.
I've changed the core myself on the same SUV. It's a big job that you need the right skills to do. The dash needs to be removed or pulled way back out of the way and the A/C will need to be discharged and recharged for two.
If needed you can bypass the core by removing the hoses from the metal pipes under the intake plenum and connecting a hose between them.

Did you find out what that part was? ( the slim small looking radiator )

I have the 04 Durango 4.7l and faced the same issue, I replaced the auxillary (electric) pump once ($150) and the engine quit over heating for about a month until pump gave out again. I have since by-passed the pump and I no longer have heating or cooling issues! I'm sure the pump serves a purposse but I remember my father buying a new k car back in 80 and he needed to place a plastic jug over alternator cap because it sat in a perfect location where heat from the engine and the cold air caused moisture to under the cap. Not all designs are good!
#155 of 168 2003 DURANGO OVER HEATING ?
Apr 30, 2012 (2:11 pm)
I HAVE A 2003 DODGE DURANGO WITH A 4.7 LITER ENGINE, I HAVE BEEN HAVING OVER HEATING ISSUES WITH IT, I HAVE CHANGED THE WATER PUMP, FLUSHED THE RADIATOR, CHANGED THE THERMOSTAT. CHECKED THE CLUTCH ON THE FAN AND MADE SURE THE ELECTRIC FANS COME ON AND STILL CANT DRIVE 2 MILES WITH OUT THE HEAT GAUGE PEGGING.
MY QUESTION IS I KNOW I HAVE A REVERSE FLOW STYLE WATER PUMP BUT WHEN IT'S RUNNING HOW FAST SHOULD THE WATER FLOW BE WHILE LOOKING AT IT THROUGH THE TOP RADIATOR HOSE. BECAUSE THE FLOW I SEE IS HARDLY ANY AT ALL. DO THEY MAKE A HIGH VOLUME WATER PUMP THE KIND WITH METAL FINS IN STEAD OF THE PLASTIC CIRCLE DESIGN. ANY IDEAS ?

I would check different part of the radiator to make sure there are I spots that migh be cool while others are hot. The flow you see might not be good because the thermasat is closed. Other then that if you have no leaks and the rad seems fine no clogs in it could be a head gasket. See if you have white smoke from the exhaust or take the cap of the rad while it is running at normal or even higher then norm temp back up and have some one pop the throttle once. If she blows like old faithful it's almost a sure sign of a head leak. Let me know how you make out.

#158 of 168 o4 durango overheating

O4 durango still overheating, I have replaced waterpump, thermostat, fanclutch, radiator,and radiator cap, drive belt, and flush out system. still overheating. No water in oil and no white smoke or water out tail pipe. With cap off I do get a little blow pressure out of radiator. Any sugestions?
May 26, 2012 (9:01 am)
Replace auxiliary water pump & hoses. I have replaced both water pumps, thermostat, radiator, hoses, clutch fan, basically anything that has to do with cooling. My 04 finally stopped o/h. Also, make sure the coolant is the original dodge coolant. Good luck!

Auxilary waterpump was leaking, took small pipe and joined two hoses together to bypass, so water will flow. Do you think that may be the problem because the water isn't circulating into the other heater core in back?
