Chrysler 200 Belt Tensioner Failure and Slipping Issues

Had the same belt squeal issue on my 2013 Chrysler 300 with the V6 engine. The serpentine belt started making noise during cold starts and eventually became constant. The problem turned out to be more than just the belt tensioner. The entire belt drive system needed attention. The idler pulley bearings were worn, causing misalignment and improper belt tension. This was causing premature wear on the serpentine belt itself. The fix required replacing: Belt tensioner assembly, Idler pulley, Serpentine belt, Checking pulley alignment on all accessories This was a serious repair that needed immediate attention. Ignoring these symptoms can lead to complete belt failure, which affects multiple engine systems including power steering, alternator, and AC compressor. The repair significantly improved engine performance and eliminated all unusual noises. Worth having a professional inspect the entire belt drive system rather than just replacing individual components. Belt tensioner issues often indicate wider system wear that should be addressed together.

Thanks for sharing your experience. I had a very similar engine noise issue with my Chrysler 200 last winter. The idler pulley was making that distinct squealing sound, especially during cold starts. Did you end up needing any additional repairs beyond what was initially diagnosed? I am curious about the total cost too, as I had to replace several components in the belt drive system and wondering if the prices were comparable. After automobile maintenance like this, its smart to keep monitoring for any related issues that might develop.

I got the repairs done last month, and the results have been great. The noisy belt tensioner was indeed the main culprit, but the mechanic was thorough and spotted a few related issues that needed fixing. The total came to 455€ for the belt tensioner replacement and labor. The serpentine belt system is now running perfectly smooth with no engine noise at all. Engine performance has notably improved since the repair. It was absolutely worth fixing it properly rather than trying temporary solutions. The mechanic confirmed that waiting longer could have led to complete belt failure. No additional repairs were needed beyond what was initially diagnosed in my case. The squealing noise during cold starts completely disappeared after replacing the faulty belt tensioner. Just make sure you get the entire belt drive system checked while they are working on it, prevention is always cheaper than dealing with a failure later. My recommendation would be to monitor engine noise levels for the next few weeks. If you notice any unusual sounds from the idler pulley or belt area, get it checked right away. A properly functioning belt system is crucial for overall engine health.

I finally took my Chrysler 200 to a local repair shop last week. The engine noise from the serpentine belt was getting worse, and I knew I couldnt put it off any longer. The inspection revealed worn idler pulley bearings and a failing belt tensioner, just as suspected. Total cost came to 520€ for parts and labor. They replaced the belt tensioner, serpentine belt, and idler pulley. The entire belt drive system got a thorough check during the repair. After a week of driving, the car runs perfectly now. No more squealing during cold starts, and engine performance is noticeably better. The shop did a great job explaining everything and showing me the worn parts they replaced. Really glad I got this fixed before the belt failed completely. Thanks for helping me understand what I was dealing with. Will definitely keep an eye on the belt drive system during future maintenance checks.
