Hi i have a Dodge caravan 2005 3.8l engin and its make a small noise someware in the front were the timing belt is , i have checked the sterring fluid and its okay , and the sound dont get louder when a turn the steringwheel, i have replaced the tensioner but with no resoult ,could it bee the waterpump?when a take away the timingbelt and start the car the sound is gone! so it most bee the steringpump or the waterpump but with??

 

LOL the belt u remove aint called a timing belt.....its a serpentine belt....

Maybe de Power steering pump has a lil air in the system
Maybe de water pump going away slowly....(look under the car near the water pump pulley......is it all pink n ****?) if so its leaking....common on these cars

 

Hi i have changed the waterpump and the serpentine tensior but the nois is still there, the noise dont get louder when a move the steering wheel,the power steering fluid is okay, when a remove the belt and start the car the sound is gone ,what can it bee, the sound isent loud so its hard to detect!!!

 

There are some sounds that are just going to be there,no matter what you do.
You might try spraying a little water onto the belt while the engine is running and see if the sound changes.

 

the answer to your problem is the idler pulley

 

The alternator clutch is a common noise culprit.
