all of a sudden, my dodge durango 2004 4wd 4.7 engine began overheating and leaking coolant. to date, i have changed the thermostat, relay, water pump, and fan clutch. the car is no longer leaking coolant, but is still overheating in the worst way. al of these repairs were done within a two week period. i still can't use the car. help! any suggestions?

We just had this happen to ours. I traced the leak back to a auxiliary or secondary pump up near the firewall (passenger side). It's a bosch magnetetic driven pump. After searching all over the internet for replacement, and not finding one for Dodge, I've decided to compare pictures and found similar in many german made vehicles, i.e. BMW, VW, etc. I'm going to call the dealership and see what they have, but they don't open 'til Monday... In the meantime, I pulled the pump, put in a 2" PVC nipple, so it is now bypassed. That fixed my leak and after idling for a half hr. it seems to be holding temp. I'm going to take it for a drive and cross my fingers. here is a link that shows the pump. Hope this helps, if you find out any more, reply to this post, maybe I'm missing something else...

I just had the same problem happen to me today. If it is the auxiliary pump, I purchased mine from the dealer for $102.00 (after a 25%) discount. I installed it in about 20 minutes (and I am no mechanic). It is 2 clamps and a switch (that's all).
You can tell it is the auxiliay pump if the fluid is leaking behind the right front tire. You should see 2 puddles (one large puddles with coolant and 1 smaller puddle from the A/C). By the way, for those of you who don't know what the pump does, this is what I found thanks to Hartwells797 link (A replacement auxiliary water pump will ensure that your vehicle receives ample cooling water after shutdown and during critical engine phases).
Good luck and I'll keep you posted if I still have leakage after this replacement.

Do you happen to know the model number of the replacement pump under Bosh? Thanks Bubba

I'm having the same problem, but I am not leaking any fluid. I have replaced the water pump, thermostat, fan clutch and had a radiator flush and still not luck. It overheats on the highway only, usually don't have any problems when driving in town. Anybody get any resolution to their problem?

I have flushed mine three times, replaced the water pump and taking it in in two days to replace the radiator. My secondary pump is leaking and you can get them from the dealer they told me it was $152.00. I would like to know more abut bypassing it. If anyone has just bypassed it and not replaced it and it worked let me know. I think the bypass will only work for so long because the secondary pump is needed for when it really gets hot. The temp outside does effect this because mine does not do it in the winter.

How long did the bypass work? I am wondering if you can just bypass it and leave it that way? I was told it is just for the rear heating and cooling system.

We purchased our 2003 Durango in Nov 2008 and in early 2009 we started having overheating problems. The first time it happened was the day after I got home from a 600 mile trip in February 2009. I was at a drive through and started to leave and the check gauge light came on. I looked and my temp gauge was in the red. We immediately stopped. We let the car cool down and checked the fluid levels. It did need antifreeze. We took the Durango to be looked at by a local mechanic and he could not get it to overheat. He flushed the system and change the radiator hose assembly where the radiator caps lies as a precaution.

I drove it for a few weeks locally with no problems. Then I had to go out of town on a 340 mile trip and the problem came back. We took the car back and still they could not identify the problem so they sent it off to the Chrysler Dealer to run some tests including checking the computer which checked out fine. The replace the thermostat and also recharge the ac system saying that if the system was low if could delay the fan from coming on (news to me). Well we drove it for about a month locally and nothing was wrong... then I drove another 300 mile trip and the problem is back and they have no idea why. I have read post after post of people having this same problem and I really wish there was a solution. It makes me mad, I paid top dollar less than 7 months ago and have car I cannot drive or trade in.

It is going back to the shop, now it is also getting sucky gas mileage and still will mysteriously loosing antifreeze and overheat –

We have done a huge amount of research and so has our mechanic. We are going to replace the water pump. We have also found out that if you vehicle uses DEX COOL which ours does, Dex cool is very corrosive. DEX Cool clogs the radiator and other components in your system and will in time will make the cooling components fail. In addition to the water pump change the system will be flushed twice and then we will be using the green coolant and not the Dex Cool. We are past our warranty period for the cooling system so this will not void our warranty.
GM has class action lawsuits in several states against them regarding Dex Cool and the damage it can do to you vehicle. They are not winning these cases and are having to pay out $$$$ to plaintiffs.

If this does not correct the problem we will be moving on to the engine and will be looking at replacing the heads. They have done the compression checks and it checks out fine. However there has to be a reason that the antifreeze disappears and is not leaking out. There is some concern that this is happen at the intake and when the engine is hot and expanded.

I have to say the I am not impressed with our Chrysler Dealer Service Center (Spokane Chrysler)– they acted like we were the only Durango in the world with this problem – I know that they have knowledge and honesty would have been enough to consider another Dodge/Chrysler/Jeep Product but now I will most likely never buy any of these in the future and NOTHING that uses DEX Cool.

We will keep you all posted… the saga continues.

I tried to flush my radiator 3 times and it did not work so I pulled it out took it to a parts store they tried to unclog it and couldn't so I had to buy a new radiator and put it in, If you have someone do this for you it should be around $400.00 depending on the labor. I have not had any problems since but the problem with these vehicles is that thae radiator clogs quicly so it is a good idea to flush them every 6 mo to every year.

The problem is the Dex Cool it causes corosion of the engine and other parts. There has been a settlement in a class action lawsuit with GM vehicles having the same problem with Dex Cool. I have requested a class action law suite with an attorney for Chrysler...we will see what happens. I referred them to this website and other's so you may be contacted if we can start a law suite.

Just got news from our Mechanic - he finally got to the heads and found that the head gasket was bad. The machinist is saying that this is a common problem with the gasket that was used and that they were cheaply made. They now know that the leaking and coming from the gasket deterateing to nothing and when the car heated up on long trips it allowed the antifreeze to escape. The tests that everyone ran before did not show any problems because of where and how it was leaking.

The heads will still need to be reworked and new gaskets replaced. Our warranty company is coming out today to look at it and we are praying they just say go ahead and pay for the repairs without a fight… this is something we could not have prevented and had to do with the engine all along not the cooling system.

I am not aware of anyway way to check head gaskets without pulling the heads which is not cheap…. But if this particular gasket that was used is cheaply made and has a history of this problem this may be the start of what others are facing as well. We are told that they would have never found the problem unless the head was crack (which eventually with overheating will most likely happen to many engines).

I will update when I have more news… my car has been down for almost a month now – UGH!

I have a 02 4.7l dodge dakota that will not hold coolant. There are no visual leaks and I've had it pressure tested and changed the radiator cap. I noticed the temp gauge get almost to the red zone one day, so I parked it and check the coolant and it was empty. Ever since then I've been filling the radiator about every week and a half. I also have noticed on a few occasions some white smoke when I first started the truck, but it goes away after about a minute. I fear that this also might be caused by a bad head gasket. Has your vehicle shown any of these?

We just got word that our warranty company will $1973 of the $2600 it is goiong to cost to repair the head gaskets and rework the heads. They are not covering the water pump - thermostat (already replaced once, plugs, tension rods and state tax. They are going to reimburse $60.00 total for rental car based on the # hours of actual repair time - not car down time...

I am glad I do not have to pay the whole thing but this is really spending after forking out the original cost of the warranty which was about $1800.00 -

I think I am staying away from Dodges from here on out - I figure with almost a new engine we should have some time to get the loan paid off and trade it in. Lets hope anyways....
