I'm not the most technical person when it comes to cars, but just to summarize:

I just had my timing belt replaced, but a few days later I heard a loud squealing when turning on my A/C. And every so often it would squeal VERY loud. It's not consistent, only for about 3-5 seconds when turning on the A/C, and randomly every 10 mins or so while driving.

Not sure if the timing belt is really related, but I'm assuming the mechanic had to take off the A/C belt to get to the timing belt, and maybe something just didnt get tightened?

If possible, I want to see if there's something I can do in my own garage to fix this issue before taking it back to the mechanic.

Thoughts? Thank you!

Steve

cat belts have a very high tension setting,150 and 180 ft lbs.if not correct tension belts will make noise.

also ck.upper tensioner for bad bearings.if bearings bad will cause a intermittent growl.

If memory serves me correctly, the New Belt Tensions are 190 foot pounds for the serpentine belt and 150 foot pounds for the A/C "V" Belt while the used tension is 120 foot pounds for both but I would strongly suggest checking your repair manual for the correct numbers.

As a precaution, I will tell you that the power steering pump has a second bolt that needs to be loosened in order to allow for adjustment. It is somewhat hidden and unless you know to look for it, it is easy to miss.

Below are a couple prior threads where this was discussed:

Yes, you are correct. Your post jogged my memory.
When my serpentine belt came off, I lost my alternator and power steering but the A/C still worked.
My concern at the time was that the car might overheat because I was not (at the moment) remembering that the timing belt drives the water pump.
It has been a few years since I was under the car replacing the belts. I had another car where the V belt operated the A/C. That is one of the issues with having so many vehicles and getting older, the memory is not always accurate.
Thank You for the reclarification.
