1. Locate your engine size: This information is usually found on a sticker under the hood, or in your owner's manual. Common engine sizes for a 2007 Silverado include 4.3L, 4.8L, 5.3L, and 6.0L.
2. Check your owner's manual: The manual will specify the exact oil filter part number recommended by Chevrolet.
3. Use an online parts lookup: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search by year, make, model, and engine size to find the correct oil filter.
Without knowing your engine size, I cannot tell you the specific oil filter you need. Providing your engine size will allow me or an online parts search to give you the precise answer.
