Service Procedure
CAUTION: 2015-2017 model year vehicles are not compatible with the press-in-place gasket
oil pan. Installation of the press-in-place gasket oil pan will result in engine damage.
1. Remove and discard the oil pan and oil pump seal. It is recommended to allow the crankcase to drain
overnight to prevent contamination of the engine sealing surface. Refer to the Workshop Manual
(WSM), Section 303-01.
NOTE: Cleaning and preparation of the engine sealing surface is absolutely critical for proper
adhesion of the new oil pan. Improperly cleaned and prepared sealing surfaces will result in an oil
leak.
2. Thoroughly clean the engine sealing surface using Motorcraft® Silicone Gasket Remover and a plastic
scraper. Allow the gasket remover to set for several minutes after application to aid in removal of the
RTV sealant.
(1). The engine block skirt stiffener sealing surface must be clean and free of any residual RTV. Do not
use metal scrapers, wire brushes, or rotary tools of any type on the engine sealing surface. These
tools will cause damage to the sealing surface including scratches or gouges that will create leak
paths. A second application of Motorcraft® Silicone Gasket Remover may be required.
NOTE: When cleaning the engine sealing surface it must be wiped clean using a lint free cloth.
Spraying the surface with brake cleaner and air drying will not adequately remove the oil and other
contaminates from the surface and may leave residue from the brake cleaner behind that may
interfere with RTV adhesion.
3. Use a lint free towel and Motorcraft® Metal Brake Parts Cleaner to remove all residual sealant and oil
from the engine sealing surface until a clean lint free towel no longer shows any residual oil when wiping
the surface. (Figures 1-2)
(1). Use only Motorcraft® Metal Brake Parts Cleaner to clean the engine sealing surface. Some
unapproved brake parts cleaners contain chemicals that will inhibit RTV adhesion or may evaporate
without removing all of the residual oil from the sealing surface which will result in a repeat leak
condition.

NOTE: Motorcraft® Engine Shampoo and Degreaser is used to remove residual brake cleaner
which can cause RTV failure and prepare the surface for the Motorcraft® Metal Surface Prep
Wipes. The use of any other brand engine shampoo or engine cleaner can compromise the sealing
surface and could lead to failure of the RTV seal and a fluid leak.

4. Use Motorcraft® Engine Shampoo and Degreaser to clean the surface of any remaining oil
contamination and prepare the surface for the Motorcraft® Metal Surface Prep Wipes. After Motorcraft®
Engine Shampoo and Degreaser, dry the surface with a lint free towel.
NOTE: Do not use Motorcraft® Metal Surface Prep Wipes on the replacement oil pan. Using
Motorcraft® Metal Surface Prep Wipes on the oil pan will contaminate the treated oil pan sealing
surface causing reduced RTV adhesion and a potential oil leak.
5. Wipe the metal engine block skirt stiffener sealing surface using Motorcraft® Metal Surface Prep Wipes.
Thoroughly coat the surface with the fluid. Discard wipes after a single use.
(1). Motorcraft® Metal Surface Prep Wipes create a conversion coating providing an improved base for
RTV sealing. The fluid is a water-based, slightly acidic solution that will etch and bond to the metal to
provide a microscopic layer to which the RTV can adhere. If the surface is oily, the solution will bead
and the surface will not be treated properly. If the solution beads when applied to the sealing surface,
the surface must be cleaned again and then the Motorcraft® Metal Surface Prep Wipes reapplied.
(Figures 3-4)
NOTE: If the sealing surface or an area of the sealing surface becomes contaminated after it has
been prepared, use a lint-free towel soaked in isopropyl alcohol to clean the area. Prepare the area
again using Motorcraft® Metal Surface Prep Wipes.

6. Allow the surface to air dry for approximately 2 minutes.
(1). Do not dry the surface using any other method. Attempting to dry the surface may result in sealing
surface contamination that may cause oil leaks.
7. Install the new oil pump seal. Refer to the WSM, Section 303-01.
NOTE: The oil pan must be installed within 10 minutes of applying the RTV.
8. Apply a 4.5 mm (0.18 in) bead of Motorcraft® High Performance Engine RTV Silicone to the new oil
pan. The RTV bead must be applied to straddle the step chamfer and sealing face. (Figures 5-6)
(1). Using too little sealant may result in oil leaks and using too much sealant may result in oil
contamination and engine damage.

9. Apply a 9 mm (0.35 in) bead of Motorcraft® High Performance Engine RTV Silicone to the engine front
cover-to-cylinder block joint areas on the new oil pan as shown in Figure 5.
10. Install the new oil pan. Refer to the WSM, Section 303-01.
