I have a 2001 Durango R/T 5.9L 4WD w/towing package.
Fought the problem and replaced the damaged radiator as well. Still smelled antifreeze and kept losing coolant as well. Found a small puddle behind front passenger tire and traced it to a device on the firewall (passenger side). After much research, the problem and solution was to replace this - the auxiliary water pump. The air is cold because this pump isn't working and probably has a leak causing the overheating as well. found one online through ebay for $89, same as OEM but Bosch (better). This overheating also caused my water pump to weep as well and replaced it too.

Hi, I've been having the same problem, replaced thermostat, fan clutch, no leaks, the same thing's happening, 'can't even drive my durango pass 30mi & it starts to heat up, you go uphill & temp easily goes up to 90%. After having the fan clutch replaced, it started to make a noise as if it is a V8 & doesn't shift well as it used to. When I first got it, the radio unit used to heat up so bad you'd be afraid to touch it, I didn't pay much attention then. Is there anything that manufacturers can do about this since so many owners are complaining? Thanks.

start by checking your heater core it could be cloged and therefor slowing down the coolant in the engine causing it to over heat good luck

oh one more thing does your coolant system need to be bled if there is air in the system that can cause it to over heat as well
#146 of 168 slowly loosing antifreeze
Dec 10, 2011 (12:32 pm)
I brought my car into the dealership due to seeing red fluid under my car (transmission fluid). As I explained the problem to the associate he actually spoke down to me (since I'm apparently just a girl) and tried to tell me it was anitfreeze and that I had red antifreeze. I had to explain that mine was green and this was transmission fluid leaking through the radiator area. As it turns out, I was right and my radiator was replaced (which I told him to fill with green antifreeze); however, he called to say that my anitfreeze was low and they had smelled a burnt smell. He wanted to do a pressure check because he was guessing my head gasket was going which would be 4000 dollars. Of course I didn't trust him by the way he treated me originally, but now my antifreeze is down some in just a month of having the radiator replaced. What could be the cause of this? Is the jerk correct? I have no overheating problems, nor any other kind. Help!

I would say this ..... If your truck Isnt over heating.... I wouldn't see any reason to be alarmed. Quick way to find out if the head is blown is to start the truck and let it get to normal temp and look for white smoke. Place your hand over the exhaust and then smell it. If you head is leaking the. It should smell like antifreeze. Another way would be let the truck cool down enough to take the radiator cap off and start the truck let it get to normal op temp. Pop the gas hard and quick. If antifreeze shoots out like old faithful the. Yes that is a blown head gasket. What happens is it pressurizes the cooling system and it blows by the bead and out the radiator. From the sounds of it you don't really have anything to worry about.
Please let me know what you find out

I had the same problem. I got a replacement auxiliary water pump from dodgeparts.com. I think that it is made by bosch. The pump can suddenly stop causing lots of antifreeze to flow out of the over flow. You then look for leaks and find nothing. Costs about $125 and is a 15 minute fix.
I still have to go to counter measures and go full heat in stop and go traffic but the sudden overheating has stopped.

I bought an 02 Durango with 95k miles and have 127K miles and still standing.
I have only used synthetic oil and changed every 3k
Replaced auxilliary water pump after sudden loss of antifreeze. Replaced antifreeze twice. Works great in Winter. Temp gauge will creep up on hot days at slow speeds. I use an auxilary electric fan and turn heater on. I call the procedure counter measures. AC works best on high way and I have been adding Freon more often then I should. Ultra Violet check showed no leaks in o rings. I am worried that When hot weather comes in May, overheating could rear its ugly head. I am considering selling the vehicle, changing the water pump and temp gauge, replacing with a larger radiator, and trying to flush out the grit mentioned by another poster.
I did not quite understand how the timing chain cover fits into the equation.
I have a 2002 4.7 SLT with tow package

My Money is on replacing the Auxilliary Water Pump on the left back side of the truck facing the vehicle. 15 minute repair. If it comes on at high speeds when it should be off, it cause fluid to back out through the overflow. All you notice is low fluid without any clue as to wher it went. 15 minute repair. Easy to do yourself. Part online is from bosch and is about $125
