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, may cause engine failure.

1. NOTE: LH shown, RH similar.

If equipped, remove the 4 nuts (2 shown) and the strut tower cross brace.





2. If equipped, detach the 2 retainers and remove the engine appearance cover.





3. Remove the Air Cleaner (ACL) outlet tube. For additional information, refer to Intake Air System Components - Exploded View, 3.7L in Intake Air Distribution and Filtering Diagrams.

4. Disconnect the crankcase ventilation tube quick connect coupling from the LH valve cover. For additional information, refer to Fuel System - General Information Quick Connect Coupling.

5. Remove the oil level indicator.

6. Detach the fuel supply tube and Evaporative Emission (EVAP) tube retainer from the LH valve cover.

7. Remove the LH ignition coils. For additional information, refer to Engine Ignition - 3.7L Service and Repair.

8. Disconnect the 2 LH Variable Camshaft Timing (VCT) solenoid electrical connectors.

9. Disconnect the Engine Oil Pressure (EOP) switch electrical connector.
- Detach the EOP switch wiring harness retainer from the cylinder head.

10. Detach all of the wiring harness retainers from the LH valve cover and stud bolts.

11. Remove the nut and the LH valve cover stud bolt wiring harness bracket.

12. NOTICE: While removing the valve cover do not apply excessive force to the Variable Camshaft Timing (VCT) oil control solenoid or damage may occur.

NOTICE: If the Variable Camshaft Timing (VCT) oil control solenoid sticks to the VCT seal, carefully wiggle the valve cover until the bond breaks free or damage to the VCT seal and VCT oil control solenoid may occur.

NOTE: The plastic electrical connector on the VCT oil control solenoid will rotate approximately 12 degrees inside the steel housing, which is normal.

Loosen the 7 stud bolts, 4 bolts and remove the LH valve cover.

- Discard the gasket.

13. Inspect the 2 VCT solenoid seals. Remove any damaged seals.
- Using the Differential Bearing Cone Installer and Handle, remove the seal(s).





14. Inspect the spark plug tube seals. Remove any damaged seals.
- Using the VCT Spark Plug Tube Seal Remover and Handle, remove the seal(s).





15. Clean the valve cover, cylinder head and engine front cover sealing surfaces with metal surface prep.

Installation

1. NOTE: Installation of new seals is only required if damaged seals were removed.

Using the VCT Spark Plug Tube Seal Installer and Handle, install new spark plug tube seals.





2. NOTE: Installation of new seals is only required if damaged seals were removed.

Using the Differential Bearing Cone Installer and Handle, install new VCT solenoid seal(s).





3. NOTICE: Failure to use the correct Motorcraft(R) High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.

NOTE: If the valve cover is not installed and the fasteners tightened within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.

Apply an 8 mm (0.31 in) bead of Motorcraft(R) High Performance Engine RTV Silicone to the engine front cover-to-LH cylinder head joints.





4. Using a new gasket, install the LH valve cover and tighten the 4 bolts and 7 stud bolts in the sequence shown.
- Tighten to 10 Nm (89 lb-in).





5. Ensure the VCT seals in the valve cover are below the top of the VCT oil control solenoid electrical connector or the VCT seal may leak oil.





6. Install the wiring harness bracket on the LH valve cover stud bolt and install the nut.
- Tighten to 10 Nm (89 lb-in).

7. Attach all of the wiring harness retainers to the LH valve cover and stud bolts.

8. Connect the EOP switch electrical connector.
- Attach the EOP switch wiring harness retainer to the cylinder head.

9. Connect the 2 LH VCT solenoid electrical connectors.

10. Install the LH ignition coils. For additional information, refer to Engine Ignition - 3.7L Service and Repair.

11. Attach the fuel supply tube and EVAP tube retainer to the LH valve cover.

12. Install the oil level indicator.

13. Connect the crankcase ventilation tube quick connect coupling to the LH valve cover. For additional information, refer to Fuel System - General Information Quick Connect Coupling.

14. Install the ACL outlet tube. For additional information, refer to Intake Air System Components - Exploded View, 3.7L in Intake Air Distribution and Filtering Diagrams.

15. If equipped, install the engine appearance cover.





16. NOTE: LH shown, RH similar.

If equipped, install the strut tower cross brace and the 4 nuts (2 shown).

- Tighten to 35 Nm (26 lb-ft).
