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 can 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 fasteners finger-tight.





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













4. Loosely install the 4 oil pan bolts, then tighten 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 starter wiring harness support bracket and the transmission cooler tube support bracket and tighten the nut.
- Tighten to 10 Nm (89 lb-in).





7. Position the starter wiring harness and starter wiring harness rear support bracket and install the bolt.
- Tighten to 10 Nm (89 lb-in).





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





9. Using the Crankshaft Vibration Damper Installer, Front Cover Oil Seal Installer and the Crankshaft Front Oil Seal Installer, install a new crankshaft front seal into the engine front cover.





10. NOTE: If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface prep and silicone gasket remover. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

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





11. Use the Crankshaft Vibration Damper Installer to install the crankshaft pulley.





12. Tighten the new crankshaft pulley bolt in 4 stages.
- Stage 1: Tighten to 90 Nm (66 lb-ft).

- Stage 2: Loosen 360 degrees.

- Stage 3: Tighten to 50 Nm (37 lb-ft).

- Stage 4: Tighten an additional 90 degrees.





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

14. Install the 3 accessory drive idler pulleys and the 3 bolts.
