CAUTION
Allow the engine to completely cool down before removing the turbocharger. The turbocharger can get extremely HOT while the engine is running and you could sustain severe burns.

  1. Disconnect the battery.
  2.  
  3. Remove the air cleaner-to-turbocharger inlet air hose.
  4.  
  5. Remove the aluminum turbocharger outlet-to-intercooler air duct.
  6.  
  7. Remove the brake master cylinder and hot water pipe heat shields.
  8.  
  9. Label and disconnect any water hoses and vacuum lines from the turbocharger.
  10.  
  11. Remove the oxygen sensor and unbolt the catalytic converter from the turbocharger.
  12.  
  13. Remove the upper retainers from the converter heat shield.
  14.  
  15. Disconnect the turbocharger oil inlet and outlet lines, and the EGR pipe. Also loosen the EGR pipe retainer at the front of the engine.
  16.  
  17. Unbolt the turbocharger from the support bracket at the lower clamp.
  18.  


WARNING
Never handle or grab the turbocharger by the wastegate linkage, as this could damage the capsule diaphragm.

  1. Remove the exhaust manifold and turbocharger as an assembly.
  2.  
  3. Separate the exhaust manifold from the turbocharger.
  4.  

To install:

  1. Assemble the turbocharger to the exhaust manifold; ensure that all mating surfaces are clean and properly aligned.
  2.  
  3. It is recommended that you use new self-locking fasteners to attach the exhaust manifold to the turbocharger. Tighten the fasteners to 33 ft. lbs.
  4.  
  5. The rest of the installation is the reverse of removal. Use new gaskets on all exhaust connections, and on the oil inlet and outlet lines. Tighten the turbocharger-to-catalytic converter bolts to 22 ft. lbs.
  6.  


WARNING
The engine should never be cranked or run with the air intake system disconnected. Damage to the system could result.
