ENGINE FRONT COVER REMOVAL / INSTALLATION - 2.3L
Removal Note
1. Disconnect the battery. Procedures.
2.
CAUTION:The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, with 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.Remove the crankshaft pulley. See - Service and Repair.
1. Disconnect the crankshaft position (CKP) sensor electrical connector and the wiring harness pin-type retainers.
1.
NOTE:A new CKP sensor must be installed whenever the old sensor is removed.Remove and discard the CKP sensor.
1. Remove the belt tensioner.
1. Remove the water pump pulley.
1. Disconnect the power steering pressure (PSP) switch electrical connector.
1. Remove the bolt and position the power steering pump aside.
1.
NOTE:This step is needed only if a new front cover is being installed.Using a three-jaw puller, remove the fan drive pulley.
1.
CAUTION:There is one bolt behind the cooling fan drive pulley. This bolt can be accessed by lining up one of the holes in the pulley with the bolt.Remove the bolts and the engine front cover.
Installation Note
1.
NOTE:This step is needed only if a new front cover is being installed.Install the fan drive pulley using a nut and bolt with flat washers.
2. Clean and inspect the mounting surfaces of the engine and the front cover.
1.
CAUTION: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.
NOTE:The engine front cover must be installed and the bolts tightened within four minutes of applying the silicone gasket and sealant.
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.
1. Install the front cover. Tighten the bolts in the sequence shown, to the following specifications:
- Tighten the 8 mm bolts to 10 N-m {1 kgf-m, 7 lbf}.
- Tighten the 10 mm bolts to 25 N-m {2.5 kgf-m, 18 lbf}.
- Tighten the 13 mm bolts to 48 N-m {4.889 kgf-m, 35 lbf}.
CAUTION:There is one bolt behind the cooling fan drive pulley. This bolt can be accessed by lining up one of the holes in the pulley with the bolt.
1. Position the power steering pump and install the lower retaining bolt.
1. Connect the PSP switch electrical connector.
1. Install the water pump pulley.Tightening Torque:20 Nm {2.0 kgf-m, 15 ft-lbf}
1. Install the belt tensioner.

NOTE:A new CKP sensor must be installed whenever the old sensor is removed.Install a new CKP sensor, do not tighten the bolts at this time.
1. Adjust the CKP sensor with the Alignment Tool, and tighten the mounting bolts.
1. Connect the CKP sensor electrical connector and the wiring harness pin-type retainers.
2. Connect the battery ground cable. See Procedures
