2007 chevy silverado 1500 5-sp belt squealing/chirping

Answers :

From what you have described I believe you have intermittent\015\012belt squeal in the serpentine belt. These tend to squeal in cold and\015\012damp weather on some vehicles and usually the noise will typically dissipate once the\015\012belt warms up from friction and radiated engine heat. This is not\015\012always the case however.

You should check the belt for \015\012wear and, if in doubt, replace it as these are quite inexpensive items\015\012which need periodic replacement in any event. Also make sure the\015\012current belt - and any replacement - is properly aligned on the pulleys.

Very often when you replace the serpentine belt the squeal will disappear but return again as the new belt "wears in". Your vehicle is probably still running the original belt so you should replace it as a first step unless you have a record of it being replaced in the past 18 months or so.

There\015\012are some temporary fixes for noisy belts which sometimes work (such as\015\012removing it and lightly spraying the belt with "Belt Grip"). There are\015\012also 1 or 2 others but I would not recommend them.

I recommend you also talk to a competent experienced service department person in the nearest CHEV dealer. You will likely find that that there will have been a number of owners coming in reporting the same issue.

Hope this helps.
