Removal Procedure
Start By:
If necessary, remove crankcase breather and bracket. Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure.
If necessary, remove the fuel filter base and bracket. Refer to Disassembly and Assembly, "Fuel Filter Base - Remove and Install" for the correct procedure.
Remove the fuel manifold. Refer to Disassembly and Assembly, "Fuel Manifold - Remove" for the correct procedure.
Remove the wastegate solenoid. Refer to Disassembly and Assembly, "Wastegate Solenoid - Remove and Install" for the correct procedure.
Remove the boost pressure sensor. Refer to Disassembly and Assembly, "Boost Pressure Sensor - Remove and Install" for the correct procedure.
Remove the air inlet temperature sensor. Refer to Disassembly and Assembly, "Inlet Air Temperature Sensor - Remove and Install" for the correct procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
