Cold start annoyance
 
Just as the temperatures started to dip below 40 degrees where I live, my car now makes this annoyingly loud squealing sound from the belts & pulleys for about 5 to 6 minutes then as the car gets warmer the sound becomes more faint (not sure if it completely goes away). I just hope it's not something more than just lubricating the belts and pulleys. Does this happen to anyone else? What do you recommend using make it go away? I tried some Prestone belt dressing and it stopped for a couple days and now it's back, noisier than ever.

Thanks.

Check the tension of your belts. Belts that are too loose or too tight will cause a squeeling, that will sometimes go away or get better has the engine warms up.

Thanks for the response. That seems to be the main culprit here, I think if it keeps up, I will just change the belt tensioner. Found one on AutoHausAZ for $104, gonna check all the other moving parts around there just in case though.
