Throttle Body Elbow

Removal

CAUTION: Before disconnecting or removing components, ensure the area around the joint faces and connections are clean. Plug open connections to prevent contamination.

1. Disconnect the battery ground cable.
2. Partially drain the cooling system.
3. Remove the supercharger outlet pipe.
4. Disconnect the throttle position (TP) sensor electrical connector.

WARNING: Since injury such as scalding could be caused by escaping steam or coolant, do not remove the filler cap from the coolant expansion tank while the system is hot.

CAUTION: Care must be taken to stop coolant entering the supercharger air intake, when disconnecting the throttle body coolant hoses.

5. Disconnect the coolant hoses from the throttle body.
^ Clamp the throttle body coolant hoses to minimize coolant loss.
^ Release the 2 clips.

6. Remove the throttle body.
^ Remove the 4 bolts.
^ Remove and discard the gasket.







7. Disconnect the brake booster vacuum hose quick release connector.
8. Disconnect the supercharger fuel tank purge line quick release connector.
^ Release the dust seal.

9. Disconnect the supercharger engine breather line.
^ With assistance release the clip.







10. Disconnect the manifold absolute pressure (MAP) sensor electrical connector.
11. Remove the throttle body elbow.
^ Remove the 6 bolts.
^ Remove and discard the O-ring seals.
^ Discard the gasket.







NOTE: Do not disassemble further if the component is removed for access only.

12. Remove the MAP sensor.
^ Remove the Allen screw.
^ Discard the O-ring seal.

13. Remove the supercharger pressure relief actuator.
^ Remove the bolt.
^ Disconnect the actuator link.
^ Remove the vacuum line.
