I just joined here in hope of getting some advice.

I have a 2004 Santa Fe with 74000 miles. I just had the serpentine belt and tensioner replaced after the original broke as I was going down the highway. Now it seems to me like the engine is much noiser than before. It sounds sort of like a diesel engine rumble on the right side of the car. It's fairly quiet at idle and gets louder as I accelerate. The dealer says it's normal for an older car to be noiser when a new belt is installed and it will get quieter as the belt breaks in. Is this true? Outside of the new noise the car is running fine, but I've got a feeling that I'm due for another ride in a tow truck.

Any insight into this would be appreciated.

 

Did they install the -37111 belt, or the -37181 belt ??

Yours should have the -37181 belt, assuming you have a 2.7L (you not posted which engine we playing with)
