How to Replace the Oil Pan Gasket in a Chevy Silverado

If you notice a trail of oil behind your Chevy Silverado, it may be time to change a worn oil pan gasket. Changing the oil pan gasket in a Chevy Silverado varies slightly from year to year and between models. However, these are the steps to change the oil gasket in most 4.8-L, 5.3-L and 6.0-L Silverado engines.

Instructions

1

Park the Chevy Silverado on a level surface and block the rear wheels to keep them from rolling.

2

Put a large bucket under the oil pan, and use a socket wrench to remove the drain plug, which will be located next to the oil filter, in the rear part of the oil pan. Let the oil drain into the bucket.

3

Remove the oil pan skid plate if your Chevrolet Silverado is a 2-wheel drive vehicle. Disconnect the crossbar, oil level sensor connector. From the lower oil pan, remove the nuts and bolts and oil pan and oil pan from the lower crankcase.

4

Wipe out the oil pan with a clean cloth or paper towel and wipe the sealing surfaces with solvent to be sure they're completely free of debris.

5

Apply a thin bead of sealant to the sealing surface and carefully attach the new oil pan gasket.

6

Reattach the oil pan, fastening the bolts securely. Replace the oil level sensor connector, crossbar, and the oil pan skid plate, if applicable.

7

Refill the engine with oil and check the level with a dipstick. Pour the old oil into an empty milk carton and dispose of it at a garage or at your neighborhood hazardous waste facility.
