Removing the oil pan on a Ford F-150 is necessary when the oil pan gasket has broken and is causing oil to leak, or when the oil pan itself is damaged. You might also remove the pan when maintenance is being performed on the bottom end of the engine. The main purpose of the oil pan is to catch all the oil when the engine is turned off. Checking the oil is accurate only when all the oil is at the bottom of the engine.
Ensure that your F-150 is parked on a flat and level surface. Set the parking brake and turn off the pickup's engine.
Place a jack under the front crossmember. Raise the truck high enough to place two jack stands under the crossmember or under the frame rails on either side of the pickup. Lower the truck onto the jack stands.
Place a drain pan underneath the engine. Unscrew the drain plug at the bottom of the oil pan with a socket wrench. Allow all the oil to drain out. Screw the drain plug back into the drain pan.
Unscrew the oil filter with a filter wrench. Place the oil filter with the waste oil.
Locate the bolts holding the oil pan to the engine. Unscrew the 16 bolts with a socket wrench. The oil pan gasket has created a seal that will prevent the pan from falling down as the bolts are removed. Tap the pan with a hammer to break the seal.
Pull the pan out from under the truck. Scrape the old gasket material off the surface of the oil pan with a plastic scraper. Scrape any gasket material off the bottom surface of the engine as well.
Always contact a recycling centre for disposal of the engine oil and oil filter.
