Engine Installation
1. Install the accessory brackets, and tighten their bolts to the specified torques.
2. Install the engine into position in the vehicle.
NOTICE: Reinstall the mounting bolts/support nuts in the sequence given. Failure to follow this sequence may cause excessive noise and vibration, and reduce bushing life.
3. Install the right side engine mount bracket, then tighten the bolts and nut in the numbered sequence shown.
4. Tighten the support nut on the left side engine mount bracket.
5. Install the upper radiator hose.
6. Install the heater hoses (A) and lower radiator hose (B).
7. Raise the hoist to full height.
8. Install the engine stop bracket (A), then install the engine stop bracket cushion (B).
9. Install the front tires/wheels.
10. Lower the hoist.
11. Tighten the two bolts securing the engine stop bracket.
12. Install the Evaporative Emission (EVAP) canister hose.
13. Install the brake booster vacuum hose (A), fuel return hose (B) and fuel feed hose (C), using new washers (D).
14. Push the Engine Control Module (ECM) connectors through the bulkhead, then install the grommet (A).
15. Install the battery cable (B) on the auxiliary underhood fuse box. Install the ground cable (C) and harness clamps (D).
16. Connect the ECM connectors (A) and main wire harness connector (B).
17. Install the harness clamps (A), then install the battery cable (B) on the main under-hood fuse/relay box.
18. Install the Electrical Power Steering (EPS) control unit.
19. Install the vacuum tank.
20. Install the throttle cable, then adjust the cable.
21. Install the transmission.
22. Clean the battery posts and cable terminals with sandpaper, then assemble them and apply grease to prevent corrosion.
23. Refill the engine with engine oil.
24. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open.
25. Check that the transmission shifts into gear smoothly.
26. Inspect for fuel leaks. Turn the ignition switch ON (II) (do not operate the starter) so that the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
27. Inspect the idle speed.
28. Inspect the ignition timing.
29. Enter the anti-theft code for the radio, then enter the customer's radio station presets.
