how do you tell what size V8 you have if not under the hood and no paperwork, 4.8 or 5.3
its the eighth number or letter in the vin# "J" is LY5 5.3
It might be on the driver side door post if not as the first guy said it is in the VIN number.
Lift your hood and there should be a gray/white sticker with engine information it has the Litre info posted about the middle
The said the sticker ant under the hood. Read the question before you try to answer.
it won't be in the door jamb. get your VIN and call your local dealer, they can look it up for you.
I called 2 dealers gave them the vin got 2 different answers
