it is on a sticker adhered to your radiator shroud.
if it is removed, damaged, or unclear...

one tip - if you look by the crankshaft pulley to the right you will see a tubular looking shaft about 1" diameter , you will notice you can't get the belt out from under this piece , it has a nut on it , once you take the nut off , you will notice it has a star shaped point on the tip of the stud , it requires a reverse torx socket or wrench to remove the stud , when you get the stud out the tube piece it can be removed , then the belt comes off , replace the belt , now comes the tricky part , fitting that tube spacer back into its spot , it can be difficult , once its in place put the stud back in , and put the nut on and tighten it.
