I'm sure someone can tell me an easy way of checking this. I've been driving an 03+ Escalade the past couple of days. The dealer I take one of my cars to gave it to me while it was there being serviced. I'm trying to figure out if it has the 6.0 or the 5.3. I know previously all 2wd's had the 5.3 and all awd's had the 6 liter however, this year both have it. Can you all please tell me an easy way to figure this out? The owners manual isn't present and the door stickers don't indicate an obvious answer either. Thanks!!!!!!!
