for some of you dodge owners let me tell you this vehicle is nuts i have a 2002 dodge durango that has pissed me off since the day i bought it. It overheats when it sees fit i had a flush hoses checked waterpump replaced , and a part no one even a dodge dealership never new existed called the auxillary pump many people have had success with replacing that I did for awhile it ran without overheatin but has started doing it again. took it to a dealership had the thermostat replaced 3 times. Fan works and kicks on used to spew antifreze but doesnt anymore i swear these vehicles are haunted or something one day they work perfect the next they overheat two block down the road wth????

This problem with overheating Durangos surely would carry enough weight for Dodge to issue a recall and fix this obvious design flaw in these trucks. I've got an 04' with the 4.7 and until recently hasnt given me much trouble. I've only went thru 3 water pumps, 3 thermostats, 2 fan cluthes and countless times of riding with the heater on full blast just to make it down the road. With summer only half over I figure either i'm looking at up to $500-$1000 total cooling system replacement or the nearest carlot willing to trade. Any advice anyone???? Oh yeah the secondary or auxillary water pump, I've removed it and just connected the two lines together with a metal coupling. Does this pump really make that much difference?? I've found a replacement online for $76 thru Bosch. My truck does NOT have rear heat/air.

Have you had the system fluhed? If so, did they replace the fluid with the same from Dodge? If not, it will overheat.....weird I know, but it happened with my '04. I love my Durango, but the cooling issue should carry the weight to have them recalled and repaired.

Does anyone have any idea just where this auxiliary pump is located, somewhere under the battery maybe? What all has to be taken off to get to this pump, do you get to it from under the engine? Very frustrating trying to figure out how to stop this overheating. I've replaced my water pump which did go bad and leak antifreeze, changed the thermostat, fan seems to run fine, the auxiliary pump is the next thing to try to replace if I can locate it.

OK, so my husband wants me to clarify that it is leaking out the overflow slowly, even when the temp is reading normal. We've tried heavier radiator caps, and it still makes it's way to the overflow. We even replaced the upper hose assembly where the cap goes.

"it is leaking out the overflow slowly, even when the temp is reading normal"
If that's the case, then are you sure it's not just overfilled and being forced out when the coolant expands with temperature?

No, its not overfull. I can suck the excess that is in the overflow, fill the radiator, start my trip, drive 200 miles on the highway and the car will get hot (from loss of coolant), and take nearly 2 gallons of coolant to get going again. That is starting with a full radiator and an overflow at a good level. It just continually sends coolant to the overflow, never sucking it back into the radiator. Isn't it supposed to send coolant to the overflow ONLY when the car is hot? I filled my radiator Monday, drove around town for 2 days, and had to put a quarter of a gallon back in the radiator on Wednesday> Aaaackkk!!! Need help on what to change next!!!

I just had the same problem with my 2000 Durango over heating. I replaced the clutch fan drove from York Pa to Atlanta Ga. I made it 4 miles from the Ga border and broke down. I rebuilt my motor. The head gaskets where blown out and my heads where badly damaged. I bought new heads, new water pump, new hoses, thermostat, I had my engine block vated and magnafluxed to check for damage which that did come back fine. So basically I have a brand new motor now and 2500 dollars later. Just took it for a test drive today.... It runs warm but not hot. I think I might be putting a 3 wall radiator in next. I would like to find a thermostat that was like 180 or lower but according to all places I have tried they only make a 195 stat for this truck. This is want I have done so far. Not sure if it helps you but I think these trucks run to hot from factory!

I fixed it!!!! Got to thinking about how the transmission runs thru the rad as well as the coolant. Right well the temp from the trans at least on my truck on the return line was around 170 where I tested it. Well the temp of my tuck was running around 212 at an idel and on the road or high way it was getting as high as 230 to 235. I did replacemmy rad but I was still concern about the warm temps. I have read very many blogs forums and such about this 4.7 L motor not having a good cooling system or the rad was to small. So I went and got a 60 trans cooler today installed it and I have not been able to get the truck to even go any high then 194 and the stat is a 195 stat. I am very happy now and I hope this help people with their over heating problems. I think the trans just produces to much heat. I got an heavy duty torqflow trans cooler fro
 AutoZone like 60 bucks. Thanx for everybodys feed back on this problem
 
Ps
Btw my trans temp went from about 170 to going back in the trans around 107 to 98 now the rad doesn't have to work as hard and I ran the lines in the rad and out to the trans cooler back to the trans it self and it is
Mounted in front of my ac condinsor work Awesome

 
Sorry for misspelling or things that might make no since I typed this on an iPhone. My eyes are crossed now
