Removal Procedure
Start By:
If the engine is equipped with a turbocharger, remove the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove and Install" for the correct procedure.
For C2.2 remove tube assembly from the exhaust gas recirculation valve and the exhaust cooler (NRS). Refer to Disassembly and Assembly, "Exhaust Gas Recirculation Valve - Remove and Install" and refer to Disassembly and Assembly, " Exhaust Cooler (NRS) - Remove and Install" for the correct procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
