Hello, I have a 2003 Chevy Impala and I noticed that it is leaking a green liquid from a silver canister. Its located on the driver side next to the radiator, below What I'm guessing is the intake. I just want to know what this silver canister is really. I uploaded a picture. Thanks in advance.

 

you have an a/c leak. The fluid is pag oil with a fluorescent dye in it. your a/c doesn't work i'll bet. The cylinder is the reciever/dryer.
