Mark the area to be drilled, centering the drain hole below the third bolt hole from the driver's side on the front of the oil pan, 1.5-inches from the oil pan rail.

With the oil pan secured on a workbench, drill the outer bolt holes to 1/4-inch, the center drain hole to 1/2-inch, deburr the holes and thoroughly clean the oil pan to remove any metal shavings.
