The engine noise from my 2000 Durango suddenly got louder while I was driving on the interstate at about 70 mph. I thought it might have been from the cold weather, but I had been driving for about 20 mins and the engine was warm. The check engine light didn't come on, and it continued to shift gears as normal all the way home, the car was just a lot louder. Any suggestions???

does it sound like the engie is roaring? Like a loud fan noise? If so thats your fan clutch seized up... with the engine off, try to spin the fan thats connected tothe engine via a belt... it should spin rather freely...

A seized fan clutch will really hurt your fuel mileage, and thats about it... it may put some extra strain on your accessories belt, so if its old it may break, but thats about all I can think of...

if this isnt the case, give us a more descriptive sound, as well as the engine size in your Durango...

If it is the clutch fan and you also have the electrical fan(s), you can just remove it and keep it off. The electrical fan will keep it cool.

Onebadkota:

This is not accurate advice. The electric helper fan(on the Durango anyway) is there to supplement the mechanical fan when the A/C is on, and when it is super hot out.

By removing the mechanical fan, you will overheat when stopped in traffic and at slow speeds. You would have to run the A/C all the time to have the electric fan operate.

IIRC, the helper fan did not come about till the 00 model year.

yea the helper fan is on the durangos w/ the 4/7 i thinkg and if its not the clutch fan when that happened to me on my old truck the after-cat o2 sensor had fallen out so maybe check the exhaust for leaks??

What about just a plain old exhaust gasket?

There are plenty of other things that it could be. First lets get the model, year, engine, and what ever that could help this problem.

I think a lot of us tend to jump on problems without the proper info. This can lead to excessive parts, time, and money. This is why we are all here right?
