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.

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?

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?

Hello, I am having some issues with my 2000 Durango 4.7l. Any help would be greatly appreciated. I will apologize now for anymisreads or spelling mistakes, I am posting this via my cell phone. Also, I wish tp thank you in advance!
 
Heres the deal: I bought the truck about 5 months ago. The vehicle currently has 216xxx KM and is for the most part in good condition.
 
 In short:
Truck is severely overheating, losing a lot of coolant with NO external leak (even under pressure), cylinder 8 is still misfiring (despite changed plugs), there is a coolant smell coming from the vents inside cabin but no wondow fogging or wet floors. Coolant seems clean of oil and oil looks free of coolant. I cant tell what color the exhaust is or if I smell coolant... I smell exhaust.
 
Long version:
When I bought the truck there was a smell comong from the vents but didnt know what it was until recently when I was told it was coolant/antifreeze. The windows dont fog up nor is there moisture on the passenger side floor. About a month ago, my gauge light came on telling me to check my gauges, when I did I saw that the truck had been overheating and was almost in the red. I pulled over as quickly as possible and let it cool for over an hour. Upon inspection, I found my coolant holding tank was full but my rad was empty. I filled her up and went on my way (drove from BC to Seattle ~270km) the truck was fine but I noticed that the rad was missing a bit of coolant again, so I toped ot up amd continued to keep an eye on it daily. For the first 3 Weeks_ish I was adding less than a cup of water but adding water daily and the check engine light came on (code p0308- cylinder 8 miscire), so I took it to the shop. There are no external leaks, even when put under pressure. The mechanic said to keep an eye out amd keep track of how much I was adding.
About 2 Weeks ago it overheated again and again almost to the red. I pulled over and filled the rad again. Over the last two Weeks I had been adding a lot more coolant to the rad. The truck also began running rough. I brought it back to the shop (4 daus ago) where I had the spark plug for cylinder 8 replaced, the rad placed under pressure again and the code reset. Again there were no external leaks. Next day the check engine light was on again and reading the same code, cylinder 8 misfire.
2 days ago I left for Seattle again, despite the truck now running rougher than before with idle around 550 (lower than the smooth 700 it usually idled at). Before I left home Iade sure all fluids were toped up and went on my way. It wasnt long before I began to overheat again. I pulled over waited added a lot of coolant and went on my way. About an hour to 1 1/2 hrs later I start to overheat again, I pull over and add the remaining coolant (at this point I had added a gallon of coolant since the morning when I toped up fluids). What I added wasnt enoigh and I ended up having to add another half gallon of coolant. Where is it going?
 
Any ideas?

Late as this is I am finding out that the timing cover sort of, falls apart with time. These particles then get lodged in smaller coolant passages and clog it. Aside from Dodge making this nightmare design, they take no responsibility for all the engines it seems to have killed.
