What is your question?
Loud sounds when idling coming from the top of the motor....when I take off the vacuum hose it stops. What could it possibly be???
What makes this problem better or worse?
Taking off the vacuum hose makes it better, when the a/c is on it is worse.
How long has your 2005 Dodge Grand Caravan had this problem?
A few days

Hi! this is Bo with Car Genius at RepairPal! Loud sounds from your 2005 Dodge Grand Caravan while idling sounds serious! It could be due to a few different issues. The Valves: One possible cause of a rattling noise in your Dodge Caravan’s engine is the valves. Over time, the clearance between the valves and their corresponding parts may become too tight or too loose, leading to a ticking or rattling noise, especially at idle. Belt Tensioner: The noise could be the belt tensioner jumping at idle. Once you get it above idle, it stops hopping and the noise goes away. A/C Compressor or Clutch: I think this is most likely the culprit nd removing the vacuum hose is simply a coincidence. The Vacuum System: Given that removing the vacuum hose seems to alleviate the problem, it’s possible that there’s an issue with the vacuum system itself. It could be a vacuum leak or a problem with one of the components that the vacuum system operates. If you have any other questions feel free to give us a call at 877-913-1554!
