Supercharger: Service and Repair

Supercharger Replacement
Removal Procedure

Caution: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.

Notice: Servicing of the supercharger unit itself is limited to replacement only. No attempt should be made to disassemble the supercharger, as parts damage may result.





1. Disconnect the negative battery cable.
2. Remove the Exhaust Gas Recirculation (EGR) valve heat shield (1), nut (2), and the bolt (3).
3. Remove the supercharger drive belt.
4. Remove the fuel rail assembly.
5. Disconnect the manifold absolute pressure (MAP) and the barometric pressure (BARO) sensor electrical connectors.
6. Disconnect the vacuum hoses from the MAP.





7. Remove the MAP and BARO sensor bracket bolts.
8. Remove the MAP and BARO sensor bracket.





9. Remove the boost control solenoid.
10. Disconnect the vacuum lines from:
^ Supercharger bypass valve
^ Manifold vacuum source
11. Disconnect the electrical connectors from:
^ Supercharger bypass valve
^ EGR valve
^ Evaporative emission (EVAP) purge valve
^ Mass air flow (MAF)/intake air temperature (IAT) sensor
^ Electronic throttle control (ETC)
12. Remove the air cleaner intake duct.





13. Remove the left side supercharger bolts (1,3).





14. Remove the right side supercharger bolts (1,3).
15. Remove the supercharger.





16. Remove the supercharger gasket.





17. Remove the supercharger O-ring seals.
18. Clean the lower intake manifold-to-supercharger mating surfaces.
19. If replacing the supercharger remove the:
^ Throttle body
^ Positive crankcase ventillation (PCV) valve
^ Supercharger bypass valve
^ Manifold vacuum source

Installation Procedure
1. If replacing the supercharger install the:
^ Manifold vacuum source
^ Supercharger bypass valve
^ PCV valve
^ Throttle body





2. Install the new supercharger O-ring seals.





3. Install the new supercharger gasket.

Important: Do not use any sealer on the gasket.






4. Install the supercharger.

5. Install the right side supercharger bolts (1, 3).

Notice: Refer to Fastener Notice in Service Precautions.





6. Install the left side supercharger bolts (1,3).
Tighten the supercharger bolts starting from the center and working to the outside of the supercharger to 23 Nm (17 ft. lbs.).
7. Install the air cleaner intake duct.
8. Connect the electrical connectors to the:
^ Electronic throttle control (ETC)
^ Mass air flow (MAF/IAT) sensor
^ EVAP purge valve
^ Exhaust Gas Recirculation (EGR) valve
^ Supercharger bypass valve
9. Connect the vacuum lines to the:
^ Manifold vacuum source
^ Supercharger bypass valve
10. Install the boost control solenoid.





11. Install the MAP and BARO sensor bracket.
12. Install the MAP and BARO sensor bracket bolts.
Tighten the bolts to 30 Nm (22 ft. lbs.).
13. Connect the vacuum hoses to the MAP sensor.
14. Connect the MAP and the BARO sensor electrical connectors.
15. Lightly coat the fuel injectors (3) with clean engine oil.





16. Install the fuel rail assembly (1) to the lower intake assembly.

Important: Ensure the fuel rail is fully seated in the lower intake manifold assembly.

17. Install the supercharger drive belt.





18. Install the EGR valve heat shield (1), nut (2) and the bolt (3).
Tighten the nut and the bolt to 10 Nm (89 inch lbs.).
19. Connect the negative battery cable.
20. Inspect for fluid or vacuum leaks.
