1. Turn OFF the ignition.
2. Drain enough of the engine coolant to prevent leakage from the throttle body coolant bypass hoses. Refer to Cooling System Draining and Filling in Engine Cooling.
3. Disconnect the breather tube from the air intake tube. Refer to Air Cleaner Inlet Duct Replacement .
4. Remove the air intake tube.



5. Disconnect the idle air control (IAC) valve electrical connector.



6. Disconnect the throttle position (TP) sensor electrical connector.



7. Disconnect the accelerator controls cable. Refer to Accelerator Control Cable Replacement .



8. If applicable disconnect the cruise control cable from the throttle lever and accelerator bracket.



9. Remove the accelerator control cable bracket. Refer to Accelerator Control Cable Bracket Replacement .
10. Unsnap the wire harness clip from bracket.



11. Disconnect the throttle body coolant bypass hoses.
12. Disconnect the heater pipe nut at the throttle body.
13. Remove the nuts and bolts holding the throttle body to the intake manifold.
14. Remove the throttle body assembly.

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. Clean the gasket surface on the intake manifold and the throttle body assembly.
2. Install a new gasket, if necessary.
3. Install the throttle body assembly.

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.

4. Install the throttle body retaining nuts and bolts.

Tighten
Tighten the throttle body retaining nuts and bolts to 28 N·m (21 lb ft).

5. Connect the throttle body coolant bypass hoses.
6. Connect the heater pipe nut at the throttle body.



7. Connect the IAC valve electrical connector.



8. Connect the TP sensor electrical connector.



9. Install the accelerator controls cable bracket. Refer to Accelerator Control Cable Bracket Replacement .
10. Install the wire harness clip.



11. If applicable connect the cruise control cable to the throttle lever and accelerator bracket.



12. Connect the accelerator controls cable. Refer to Accelerator Control Cable Replacement .



13. Install the air intake tube. Refer to Air Cleaner Inlet Duct Replacement
14. Connect the air intake tube.
15. Connect the IAT sensor electrical connector.
16. Connect the breather into the air tube.
17. Fill the coolant. Refer to Cooling System Draining and Filling in Engine Cooling.

Important: The throttle should operate freely without binding between full closed and wide open throttle.

18. Inspect for complete throttle opening and closing positions by operating the accelerator pedal. Also check for poor carpet fit under the accelerator pedal.
