REMOVAL & INSTALLATION
See Figures 1 through 5
The 3.0L engine's throttle body is a 1 piece casting which includes the upper intake manifold. In order to remove the throttle body, the entire upper manifold must be removed. Refer to Engine & Engine Overhaul for the proper procedures.
- Loosen the air inlet tube clamps, then separate the tube from the throttle body and air cleaner housing. Remove the tube from the vehicle.
- If equipped, remove the throttle linkage shield.
- Detach the accelerator and speed control (if equipped) cables from the throttle body lever.
- Label and disengage the engine wiring harness connectors from the Throttle Position (TP) sensor and the Idle Air Control (IAC) valve; both are mounted on the throttle body.
- Remove the four mounting nuts, then carefully separate the throttle body from the upper intake manifold.
- Remove and discard the old throttle body-to-intake manifold gasket.
If scraping is necessary to clean the remaining gasket material off of the mating surfaces, take care to avoid scratching or gouging the soft aluminum.
- Clean the gasket mating surfaces of any residual gasket material.
- Install the throttle body, along with a new gasket, onto the upper intake manifold. Install and tighten the mounting nuts in a crisscross pattern to specifications.
- Engage the TP sensor and IAC valve wiring connectors and remove the temporary labels.
- Reattach the accelerator and speed control cables, if applicable, to the throttle body lever.
- If removed, install the throttle linkage shield.
- Install the air inlet tube between the air cleaner housing and the throttle body. Tighten the tube clamps until snug.
