Squeal from Engine When Accelerating – What Could It Be?

Technical Discussions
1

I’m experiencing a weird squealing noise coming from my engine whenever I accelerate. It’s really started to concern me, and I’m trying to figure out what could be causing this sound. Here are the details:

  • Car Make/Model: [Specify your car make and model]
  • Mileage: [Add mileage]
  • When it happens: Mostly during acceleration, especially when going uphill.

I’ve read that it might be related to the serpentine belt or possibly the alternator belt. Could it be something more serious?

Questions I’m hoping to address:

  • What are the common causes for this kind of noise?
  • Is it safe to drive while this is happening?
  • What types of repairs should I be expecting? Any ideas on cost?
  • If anyone has experienced something similar, your insights would be greatly appreciated!

Thanks in advance for any help!

I’ve been experiencing a similar squeal when I accelerate. It could be due to worn serpentine belts. Has anyone checked their belts recently?

3

That’s good to know! I heard that a failing tensioner might also contribute to the problem. Could it be worth checking both?

4

Definitely! The tensioner can cause uneven wear on the belt. Another thing to consider is the pulleys; they’re often overlooked but can lead to similar noises.

5

I’ve had issues with pulleys before! They can wear out over time and create a squealing that can increase with speed.

6

It might also be worth considering the alternator belt. If it’s worn, it can squeak when accelerating too. Has anyone looked at that?

7

Good point! It’s useful to eliminate options one by one. Regular maintenance is key for these parts.

I was just about to mention, sometimes the noise can indicate deeper engine issues, like bearings that are starting to fail. Always worth a full check-up.

That’s a bit concerning! I’m hoping it’s just the belts, but I’ll keep that in mind. Better safe than sorry!

As a mechanic, I can say that most squeaky sounds relate to belts or pulleys. But don’t ignore the potential for a loose accessory as well!

Glad to have a mechanic in the conversation! How often do you recommend inspecting these components?

12

If you’re not having issues, an inspection every 15,000-30,000 miles should suffice. But if squealing starts, check sooner!

That seems reasonable! I think mine might be due for a check-up soon.

I’ll say it again: squeals are one way of communicating! But seriously, all this info is helpful. Gotta stay proactive about my car’s health.

Squeals from the engine can often indicate issues with the serpentine belt or tensioner. If left unchecked, these can lead to more serious problems like overheating or alternator failure.

That’s a great point! It’s so important to address these noises quickly. I had a similar issue last year and caught it in time, which saved me hundreds in repairs.

19

Sometimes the squeal can be just a belt issue, but it’s wise to have a mechanic check the entire system. You never want to take chances with engine noises!

Exactly! It’s not always serious, but getting it checked is crucial. Why risk your safety?
