Installation
1. Install the intake manifold (A) with a new gasket (B), and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner bolt.
2. Raise the vehicle on the lift to full height.
3. Install the intake manifold bracket (A), then install the connector (B).
4. Install the splash shield.
5. Lower the vehicle on the lift.
6. Install the water bypass hoses.
7. Install the EVAP canister hose (A) and brake booster vacuum hose (B).
8. Install the harness bracket mounting bolts.
9. Connect the engine wire harness connectors, and install the wire harness clamps to the intake manifold.
- MAP sensor connector
- Throttle actuator connector
10. Install the intake air duct (A), then install the vacuum hose (B) and breather pipe (C).
11. Install the intake manifold cover.
12. Install the front bulkhead (A), then install the radiator upper brackets (B).
13. Apply body paint to the bulkhead mounting bolts.
14. Connect the fan motor connectors (A) and hood switch connector (B), then install the harness clips (C).
15. Install the bulkhead cover.
16. Clean up any spilled engine coolant.
17. After installation, check that all tubes, hoses, and connectors are installed correctly.
18. Refill the radiator with engine coolant, and bleed the air from the cooling system with the heater valve open (see step 6 ).
Exhaust Manifold Removal and Installation
1. Disconnect the air fuel ratio (A/F) sensor connector and secondary heated oxygen sensor (secondary HO2S) connector, then remove the three way catalytic converter (TWC) (see step 25).
2. Remove the under-cowl cover, then remove the strut brace.
3. Remove the rocker arm oil control solenoid. Remove the cover and exhaust manifold bracket, then remove the exhaust manifold.
4. Install the exhaust manifold, and tighten the bolts and nuts in a crisscross pattern in two or three steps, beginning with the inner nut.
5. Install the other parts in the reverse order of removal.

Accessory Power Sockets
Your vehicle has two or three
accessory power sockets depending
on the model.
To use an accessory power socket,
the ignition switch must be in the
ACCESSORY (I) or ON (II) position.
Each socket is intended to supply
power for 12 volt DC accessories
that are rated 120 watts or l
Lock-up System
The lock-up mechanism of the torque converter clutch operates in D position
(2nd, 3rd, 4th, and 5th), and in D position
D3 driving mode (2nd and 3rd). The pressurized fluid is drained from the back of
the torque converter through a fluid
passage, causing the torque converter clutch piston to be he
