- Remove the engine front cover gaskets.

- Clean the mating surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

- Inspect the mating surfaces.





Installation

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 all traces of old sealant.

NOTE: If the engine front cover is not secured 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. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Follow the directions on the packaging. Failure to follow this procedure may cause future oil leakage.

NOTE: Make sure that the engine front cover gasket is in place on the engine front cover before installation.

Apply a bead of silicone gasket and sealant along the cylinder head-to-cylinder block surface and the oil pan-to-cylinder block surface, at the locations shown.





2. Install a new engine front cover gasket on the engine front cover. Position the engine front cover onto the dowels. Install the 15 fasteners finger-tight.





3. Tighten the engine front cover fasteners in sequence in 3 stages.
Stage 1: Tighten fasteners 1 through 5 to 25 Nm (18 lb-ft).
Stage 2: Tighten fasteners 6 and 7 to 48 Nm (35 lb-ft).
Stage 3: Tighten fasteners 8 through 15 to 25 Nm (18 lb-ft).













4. Loosely install the bolts, then tighten the bolts in 2 stages, in the sequence shown.
- Stage 1: Tighten to 20 Nm (177 lb-in).

- Stage 2: Tighten an additional 60 degrees.





5. Connect the CKP sensor electrical connector.

6. Position the power steering pump and install the 3 bolts.
- Tighten to 25 Nm (18 lb-ft).

7. Position the transmission cooler tube and starter electrical harness support brackets and install the nut.
- Tighten to 25 Nm (18 lb-ft).

8. Connect the CMP sensor electrical connector.

9. Install the LH radio ignition interference capacitor and the nut.
- Tighten to 25 Nm (18 lb-ft).

10. Install the RH radio ignition interference capacitor and the nut.
- Tighten to 25 Nm (18 lb-ft).

11. Connect the radio ignition interference capacitor electrical connectors.

12. Install the accessory drive belt tensioner and the 3 bolts.
- Tighten to 25 Nm (18 lb-ft).

13. Install the coolant pump pulley and the 4 bolts.
- Tighten to 25 Nm (18 lb-ft).

14. Install the accessory drive idler pulley and the 3 bolts.
- Tighten to 25 Nm (18 lb-ft).

15. Lubricate the engine front cover and the crankshaft seal inner lip with clean engine oil.





16. Using the Crankshaft Vibration Damper Installer, Front Cover Oil Seal Installer and Crankshaft Front Oil Seal Installer, install a new crankshaft front seal.





17. NOTE: If not secured 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. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure may cause future oil leakage.

Apply silicone gasket and sealant to the Woodruff key slot on the crankshaft pulley.





18. Using the Crankshaft Vibration Damper Installer, install the crankshaft pulley.
