strange noise when turning off car

[nuchieboy]

well guys i just hit 31,000 miles on my 2009 camry v6 se and i have an issue. car runs great, no check engine light and motor runs strong. the problem i have is when i am turning the car off there is a strange noise coming from the passenger side of the engine compartment. it sound like some sort of vacuum leak or a squeak until the engine shuts down. it has been 90 degrees here everyday. do you think it is a dried out belt? im not really sure so im asking you guys

Have you been having your A/C on full blast every day? Both my cars will make the same kind of noise when I turn them off after the A/C compressor has been working non-stop. I myself normally don't have the A/C on unless it's unbearably hot out...I usually keep the windows down.
