CAUTION

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 can cause engine failure.

CAUTION

The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore, the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Disconnect the negative battery cable.
   
   NOTE

   To deplete the backup power supply energy, disconnect the negative battery cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies, if equipped.
   
   
3. Raise and support the vehicle safely.
4. Remove the accessory drive belt and idler pulleys.
5. Remove the engine mount.
6. Remove the valve cover.
   
   CAUTION

   Failure to position the No. 1 piston at top dead center (TDC) can result in damage to the engine. Turn the engine in the normal direction of rotation only.
   
   
7. Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at TDC.
   
   CAUTION

   The special tool 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
   
   
   
   NOTE

   The camshaft timing slots are offset. If the special tool cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.

8. Install special tool 303-465 in the slots on the rear of both camshafts.
9. Remove the engine plug bolt.
   
   NOTE

   Only turn the engine in the normal direction of rotation.
   
   
   
   NOTE

   Installing the special tool in this step will prevent the engine from being rotated in the clockwise direction.
   
   
10. Install special tool 303-507.
11. Install the special tools 205-126 and 205-072-02.

    NOTE

    Whenever the crankshaft position (CKP) sensor is removed, a new one must be installed, using the alignment jig supplied with the new part.
    
    
18. Remove the engine front cover bolts (there are 22).
19. Remove the engine front cover.
20. Remove the timing chain tensioner. Compress the timing chain tensioner, and insert a paper clip into the hole to retain the tensioner.

To install:

1. Installation is the reverse of removal. Note the following:
   
   CAUTION

   Do not use metal scrapers, wire brushes, power abrasive disks or other abrasive means to clean sealing surfaces. These tools cause scratches and gouges which make leak paths.
   
   
2. Clean and inspect the mounting surfaces of the engine and the front cover.
   
   NOTE

   The engine front cover must be installed and the bolts tightened within four minutes of applying the silicone gasket and sealant.
   
   
3. Apply a 2.5 mm bead of silicone gasket and sealant to the cylinder head and oil pan joint areas. Apply a 2.5 mm bead of silicone gasket and sealant to the front cover.
   
   
   

   

   Fig. Front cover bolt torque sequence-2.3L engine

   NOTE

   Do not reuse the crankshaft damper bolt.
   
   
   
   NOTE

   Apply clean engine oil on the seal area before installing.
   
   
7. Install the crankshaft pulley and hand-tighten the bolt.
   
   CAUTION

   Only hand-tighten the bolt or damage to the front cover can occur.
   
   
   
   NOTE

   This step will correctly align the crankshaft pulley to the crankshaft.
   
   
8. Install a standard 6 mm x 18 mm bolt through the crankshaft pulley and thread it into the front cover. Rotate the pulley as necessary to align the bolt holes.
   
   CAUTION

   Failure to hold the crankshaft pulley in place while tightening the bolt can cause damage to the engine front cover.
   
   
9. Using the special tools to hold the crankshaft pulley in place, tighten the crankshaft pulley bolt in two stages:
   1. Stage 1: Tighten to 100 Nm (74 ft. lbs.).
   2. Stage 2: Tighten an additional 90 degrees ( ¹ / ₄ turn).

   
   
10. Remove the 6 mm x 18 mm bolt.
11. Remove special tool 303-507.
12. Remove special tool 303-465.
    
    NOTE

    Only turn the engine in the normal direction of rotation.
    
    
13. Turn the engine two complete revolutions.
    
    NOTE

    Only turn the engine in the normal direction of rotation.
    
    
14. Turn the crankshaft until the No. 1 piston is at TDC.
15. Install special tool 303-507.
    
    CAUTION

    Only hand-tighten the bolt or damage to the front cover can occur.
    
    
16. Using the 6 mm x 18 mm bolt, check the position of the crankshaft pulley. If it is not possible to install the bolt, correct the engine timing.
17. Using special tool 303-465, check the position of the camshafts. If it is not possible to install the special tool, correct the engine timing.
18. Install the CKP sensor. Do not tighten the bolts at this time.
