Removal

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

2. Remove the radiator. For additional information, refer to Engine Cooling Service and Repair.

3. Remove the LH and RH valve covers. For additional information, refer to Valve Cover - LH Valve Cover - LH and Valve Cover - RH Valve Cover - RH.

4. Remove the oil drain plug and drain the engine oil. Install the drain plug when finished.
- Tighten to 23 Nm (17 lb-ft).





5. Remove the nut and position the LH radio interference capacitor aside.

6. Remove the nut and position the RH radio interference capacitor aside.

7. Loosen the 4 coolant pump pulley bolts.

8. Rotate the tensioner clockwise and remove the accessory drive belt.





9. Remove the 4 coolant pump pulley bolts and the coolant pump pulley.

10. Remove the bolt and the accessory drive belt idler pulley.





11. Remove the 3 bolts and position the power steering pump aside.





12. Disconnect the A/C compressor electrical connector.





13. Disconnect the Crankshaft Position (CKP) sensor electrical connector.

14. Remove the nut and position aside the transmission cooler tube support bracket and the starter wiring harness support bracket.





15. Disconnect the Camshaft Position (CMP) sensor electrical connector.

16. NOTICE: This bolt is a torque-to-yield design and cannot be reused. Failure to follow these instructions may result in engine damage.

Using the Strap Wrench, remove the bolt and washer and discard the bolt.





17. Using the Crankshaft Vibration Damper Remover, remove the crankshaft pulley.





18. Using the Crankshaft Front Oil Seal Remover, remove and discard the crankshaft seal.





19. Remove the front 4 oil pan bolts.





20. Remove the 15 fasteners.





21. Remove the engine front cover from the front cover-to-cylinder block dowel.
- Remove and discard the engine front cover gaskets.





22. 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.

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 with 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 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 the engine front cover with the engine front cover gasket on the front cover-to-cylinder block dowel and loosely install the bolts.





3. Tighten the 15 engine front cover fasteners in the sequence shown to 25 Nm (18 lb-ft).









4. Loosely install the 4 oil pan 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. Lubricate the engine front cover and the crankshaft front seal inner lip with clean engine oil.





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





7. 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.





8. Lubricate the crankshaft pulley sealing area with clean engine oil prior to installation.





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





10. Using a new crankshaft pulley bolt, install the crankshaft pulley bolt and washer. Using the Strap Wrench to hold the crankshaft pulley, tighten the bolt in 4 stages:
- Stage 1: Tighten to 120 Nm (89 lb-ft).

- Stage 2: Loosen one full turn.

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

- Stage 4: Tighten an additional 90 degrees without exceeding 200 Nm (148 lb-ft).





11. Connect the CMP sensor electrical connector.

12. Position the transmission cooler tube support bracket and the starter wiring harness support bracket and install the nut.
- Tighten to 10 Nm (89 lb-in).





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





14. Connect the A/C compressor electrical connector.

15. Connect the CKP sensor electrical connector.

16. Position the accessory drive belt idler pulley and install the bolt.
- Tighten to 25 Nm (18 lb-ft).

17. Position the coolant pump pulley and install the 4 bolts.
- Tighten to 25 Nm (18 lb-ft).

18. Rotate the tensioner clockwise and install the accessory drive belt.





19. Position the RH radio interference capacitor and install the nut.
- Tighten to 25 Nm (18 lb-ft).

20. Position the LH radio interference capacitor and install the nut.
- Tighten to 25 Nm (18 lb-ft).

21. Install the RH and LH valve covers. For additional information, refer to Valve Cover - LH Valve Cover - LH and Valve Cover - RH Valve Cover - RH.

22. Fill the engine with clean engine oil.

23. Install the radiator. For additional information, refer to Engine Cooling Service and Repair.
