This video will show you how to replace the oil pan gasket on various years the of the Chevy Silverado, Tahoe, Suburban, Avalanche, Express, Trail Blazer, GMC Sierra, Yukon, Savana, and Cadillac Escalade. This was done on a 2002 Chevy Silverado with a 5.3l but this procedure and pan gasket will also work on the 6.0, 5.7, 6.2, and 4.8l vortex engines. Pan gasket, oil pickup tube o-ring and oil filter were purchased from Amazon and I have provided a link to both parts below.
