Timing Cover: Service and Repair

ENGINE FRONT COVER








Removal

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. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the accessory drive belt.
3. Remove the crankshaft pulley.
4. Remove the crankshaft front oil seal.
5. Remove the engine mount.
6. Remove the coolant pump pulley bolts and the coolant pump pulley.





7. Remove the two power steering pump bolts.





Note:
^ The bolt under the power steering pressure tube will remain with the power steering pump.

8. Remove the bolts and position the power steering pump aside.
9. Disconnect the crankshaft position (CKP) sensor electrical connector.
10. Remove the CKP sensor bolts and the CKP sensor.

Note:
^ Whenever the crankshaft position (CKP) sensor is removed, a new one must be installed, using the alignment jig supplied with the new part.

11. Remove and discard the CKP sensor.





12. Remove the bolts and the engine front cover.

Installation

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.

1. 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.

2. 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.





3. Install the engine front cover. Tighten the bolts in the sequence shown, to the following specifications:
^ Tighten the 8 mm bolts to 10 Nm (1.0 kgf-m, 89 inch lbs.).
^ Tighten the 13 mm bolts to 48 Nm (4.9 kgf-m, 35 ft. lbs.).
4. Install the crankshaft front oil seal.
5. Install the crankshaft pulley.
6. Install the accessory drive belt.
7. Install the engine mount.





Note:
^ The bolt under the power steering pressure tube will remain with the power steering pump.

8. Position the power steering pump and install the bolts.
