Notice: Do not use solvent of any type when cleaning the gasket surfaces on the intake manifold and the throttle body assembly, as damage to the gasket surfaces and throttle body assembly may result.

1. Drain the radiator coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
2. Remove the air intake duct form the throttle body.
3. Disconnect the mass air flow (MAF) sensor electrical connector.
4. Disconnect the throttle body/throttle actuator control (TAC) electrical connector.



5. Remove the throttle body/throttle actuator control (TAC) retaining bolt (3) and nuts (4).
6. Remove the throttle body/throttle actuator control (TAC) assembly (1) from the intake.
7. Remove and discard the gasket (2).

1. Install the new gasket to the intake (2).
2. Install the throttle body/TAC assembly (1) to the Intake.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Reinstall the retaining bolt (3) and nuts (4).

Tighten
Tighten the throttle body retaining bolt and nut to 10 N·m (89  lb in).

4. Reconnect the throttle body/TAC electrical connector.
5. Reconnect the MAF electrical connector
6. Reinstall the air intake duct to the throttle body/TAC assembly.
7. Refill the radiator in order to replace the lost coolant. Refer to Cooling System Draining and Filling in Engine Cooling.
