Removal

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTE: Removal steps in this procedure may contain installation details.

1. Remove the engine oil filter and drain the engine oil.
   Refer to: Engine Oil Draining and Filling (303-01A Engine - 3.0L EcoBoost, General Procedures).
   

1. Remove the oil pan bolts.
   

1. 1. Lower the oil pan.

1. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges, which make leak paths. Use a plastic scraping tool to remove traces of sealant.
