It sounds like you have already replaced some components that could cause the problem, so lets go on from there. Since the car runs good for a day or two, we can assume that the external cooling parts are generally doing there job (the fans). I would take the truck back down to your mechanic and have him perform a pressure test on your radiator or you can remove the radiator and take it down to a radiator shop and have them pressure test it for you (this will tell you if you have a leak or if its clogged). My shop did it for nothing and it only took a few minutes. You also stated that the coolant is coming from the overflow. It is important not to overfill your overflow and make sure it is holding coolant. If you have a leak in your overflow, you will slowly drain your car of coolant causing it to overheat. If you overfill, obviously it will cause it blow off the excess and make it difficult to see if there is a leak somewhere else. While it sounds like you are sure there aren't any leaks, it may pay to look over your system once more. I've had a leak in my Durango that was hard to find because the plastic parts under the radiator caught almost all of the coolant. I hope this helps.

Thank you for the reply. I am truly at my wits end. The car works great for a few days than the overheating begins. Now I have no heat. If I drive with no heat the car will not overheat. I am really upset. I am in sales and my car is ESSENTIAL!!! Talk about a catch 22, I don't have the money to take it in to ge the car fixed but if I don't I'm probably going to loose me job because I'm not producing like I should be because I can't get out and see my account. I really don't know what else to do. I'm going to replace the radiator next week and pray this helps. Again, I appreciate your reply and any other info you can add. I really didn't think someone was going to respond.

Thank you for the suggestion. Over the past 2 months I have done the following...
Changed the thermostat - twice
Changed the water pump
Changed the radiator cap
Changed the Heater core
Flushed the system...
and I'm still having problems...

Been weird. For awhile, it would get hot and all of a sudden would just drop in temp to normal. Heat would not work when it was going up to hot. Lately, got hot and did not come down. Took the thermostat out...replaced it...no effect. Did a water pump before this problem started because I was loosing water...The other day, I took off both radiator hoses and ran water through the radiator and the engine in both directions. Water does come out from the upper and lower hose in the radiator and through the engine. Flushed and put back together without the thermostat. Still runs hot. Thinking radiator? Top hose gets hot but the bottom hose remains cool? Email please.

My dad's 2000 dodge durango 4.7 is overheating we replaced the thermostat thinking that was it. That did not do it. You can see the fluid circulating so it's not the water pump so at this point we are stumped. What do you think it could be. We check the timing belt cover and it is not detiorating so what now?
#74 of 163 What is the normal operating temp
Jul 14, 2010 (3:07 pm)
Just curious, what is the normal operating temp, where does that relate to on the temp gauge (1/4, 1/2, 3/4, etc).

Typically it should hover around 210F. Lower when cruising, higher when under load. when it's 115F in Arizona and I'm climbing a hill I get about 220-225F, when I'm on a flat spot it will drop back to 190 or so. I consider it normal for cooling system in good order. My Suburban was about the same, but I remember pulling a heavy trailer once and it was running at 240 or so when under load.

I have a question and you seem to be the one with all the answers. I have a 2000 Durango 2WD, it has 112,000 miles on it, I purchused it used last Feb, It started overheating, about two weeks ago, it was over 100 degress, it went to hot very fast then the check gauges light was on, once I pulled in the driveway, it made thgis loud noise and this rusty water came out everywhere through the fan thing in the front, and the top. The next day I tried to drive it, when I would stop it would turn off, now its sitting waiting to be fixed, what do I check first?
