10. Remove retaining bolts to stabilizer bar brackets.
11. Lower vehicle.
12. Lower engine assembly.
13. Raise vehicle.
14. Remove damper bolt.
15. Remove damper. If necessary use Differential Bearing Cone Remover T77F-4220-B1.
16. Remove crankshaft seal.
17. Remove lower front cover bolts.
18. Remove front cover and gasket.
19. Remove chain tensioner.
20. Remove cam sprocket bolt.
21. Remove timing chain and gears.

INSTALLATION

CAUTION: Do not use carburetor cleaner or any other solvent that will leave a hydrocarbon residue on the parts which will prevent the RTV from bonding to the engine/oil pan. Failure to completely clean the surface prior to the use of the brake cleaner or use of the incorrect solvent could result in a repeat servicing.

1. Clean and inspect all parts before installation.
2. Clean cylinder block and front cover of gasket material and dirt, and blow out any fluid in the front cover bolt holes.
3. Slide both sprockets and timing chain onto camshaft and crankshaft with timing marks aligned. Install camshaft bolt and washer and tighten to 55-75 Nm (41-55 ft lb).
4. Install timing chain tensioner and tighten to 8-12 Nm (6-8 ft lb).





5. Oil timing chain, sprockets and tensioner after installation. Install new gasket and position gasket onto front cover oil seal. Position front cover on engine loosely, and install Front Cover Aligner T84P-6019-C onto crankshaft, ensuring crank key is aligned with keyway in tool.

NOTE: The aligner tool is required because the front cover bolts are not designed to align the front cover seal with respect to the crankshaft.

6. Use Gasket Maker E2AZ-19562-B (WSK-M2G348-A5) on the two front cover lower bolts only and tighten to 8-12 Nm (6-9 ft lb). Remove front cover aligner.
7. Replace front cover seal with a new one. Install seal using Pinion Seal Replacer T83T-4676-A.
8. Lubricate the hub of the crankshaft damper with Multi-Purpose Grease DOAZ-19584-AA (ESR-M10159-A) or equivalent to prevent damage to seal during installation and initial engine start. Install crankshaft damper and bolt.
9. Remove and clean the oil pick-up tube and screen assembly. After cleaning, install the pick-up and screen assembly.
10. Obtain a tube of the new grade RTV F1AZ-19562-A (WSE-M4G320-A2) or equivalent and check the expiration date before using.

WARNING: Use adequate ventilation when applying RTV sealer.

CAUTION: Applying RTV in excess of the specified amount will not improve the sealing of the oil pan. If could cause the oil pick-up screen to become plugged with pieces of RTV.








OIL PAN GROOVES AND THE PROPER AMOUNTS OF RTV





LENGTHWISE CROSS SECTION OF GROOVE

11. Apply enough RTV F1AZ-19562-A (WSE-M4G320-A2) or equivalent in the oil pan to completely fill the oil pan groove, regardless of the groove size or configuration (see images above).





a. Have a bead approximately 5mm (0.2 inch) wide by 6mm (0.25 inch) high, above the pan surfaces, in both front and rear half-rounds.





b. Have a bead approximately 5mm (0.2 inch) wide by 4mm (0.15 inch) high, above the oil pan surfaces, along the rails.

12. Be sure that the groove is completely filled with RTV. Make certain that no air is trapped in the groove because a blow out of the RTV may occur when the engine is heated up during normal engine operations.
a. Have the nozzle of the RTV tube slightly above the oil pan groove.
b. Apply enough RTV to build up the bead above the oil pan surface before moving the nozzle along the groove.
C. Do not lay the RTV nozzle on top of the groove because this may leave air pockets, especially in oil pans with deep grooves.
13. Immediately (within 5 minutes of applying the RTV to the oil pan) install the oil pan against the cylinder block to prevent the RTV from skinning over. Tighten the oil pan bolts as follows:
a.8GTighten the oil pan-to-transaxle bolts to 40-54 Nm (30-39 ft lb).
b. Loosen the oil pan-to-transaxle bolts one half turn.
c. Tighten the oil pan flange bolts to 20-30 Nm (15-22 ft lb). Start in the center of the oil pan and work to the rear of the engine. Then, tighten the bolts from the center to the front of the engine.
d. Tighten the oil pan-to-transaxle bolts to 40-54 Nm (30-39 ft lb).
14. Install bracket from air conditioning compressor line above the oil pan.
15. Install bracket at the block and install water pump inlet tube assembly.
16. Install starter motor.
17. Install secondary air injection (AIR) tubes and connect rubber hose at the check valve (MTX).
18. Install two bolts that secure the air conditioning compressor line and the water pump inlet tube to pan bottom.
19. Lower vehicle.
20. Raise engine assembly.
21. Raise vehicle.
22. Install retaining bolts-to-stabilizer bar bracket.
23. Lower vehicle.
24. Install top front cover bolts and tighten to 8-12 Nm (6-9 ft lb).
25. Install idler pulley bracket.
26. Install idler pulley.
27. Install engine mount.
28. Install belt tensioner.
29. Remove engine support bar.
30. Install fuel line shield.
31. Install drive belt.
32. Connect battery ground cable.
33. Fill cooling system.

CAUTION: Do not add engine oil until one hour after the oil pan bolts have been tightened. This allows the outside layer of the RTV to skin over prior to coming in contact with the engine oil.

34. Fill crankcase to proper level with recommended type of engine oil.
