The turbocharger is a precision component assembled and balanced to very fine tolerances; do not disassemble or attempt repairs, as only authorized facilities should overhaul or repair turbochargers to prevent damage to both the turbocharger and the engine. For removal from a 7.3L engine, first disconnect the negative battery terminal cable(s), then remove the air filter housing along with the inlet and outlet intercooler ducts from the turbocharger manifold. Label and disconnect the manifold air heater connector, MAP sensor vacuum lines, and IAT sensor connector. Loosen the clamps and remove the turbocharger manifold, followed by the turbocharger O-ring seal and the exhaust outlet pipe clamp. If equipped, disconnect the actuator rod from the exhaust backpressure valve and label the wastegate solenoid vacuum hose. Remove the inlet ducts and raise the vehicle securely on jackstands. Disconnect the exhaust outlet pipe from the catalytic converter and transmission brace, loosen the turbocharger clamp, and remove the mounting bolts before lifting the turbocharger from the pedestal. If necessary, remove the turbocharger pedestal and replace the engine block/pedestal O-ring seals. Use soft cloths to cap open passages in the engine block during removal. For 6.0L and 6.4L engines, disconnect the negative battery terminal, wait for the engine to cool, and disconnect hoses from the coolant reservoir. Unbolt and set aside the degas bottle for access to the turbocharger intake duct, then remove the intake duct and inter cooler intake pipe. Remove pushpin retainers from the plastic cover, release retainers from the wiring harness, and disconnect electrical wiring from the turbocharger. Unbolt the oil supply line and remove large clamps from the intake and discharge ends of the turbocharger. Remove the wiring retainer and mounting bolts, lift the turbocharger, and disconnect the oil drain tube. On 6.4L engines, the dual-turbocharger assembly is heavy and delicate; use a heavy-duty engine hoist for removal or installation. For installation, clean the studs on the turbocharger mounting portion for the exhaust manifold with a die and coat them with anti-seize compound. Replace the oil supply and drain passage rings on the turbocharger pedestal, install a new gasket on the oil supply line for 6.0L engines, and install the turbocharger onto the pedestal. The remainder of the installation follows the reverse order of removal, ensuring to torque the bolts to specifications. For wastegate control rod adjustment, which applies only to 7.3L engines, note that the wastegate is factory adjusted and should not be readjusted unless damaged or replaced. Do not adjust the wastegate to increase operating pressure, as this may damage the turbocharger and engine. Disconnect the vacuum line from the wastegate control solenoid and the actuator rod from the lever. Using a hand-held vacuum pump, apply 5psi to the wastegate control solenoid, then press the wastegate control lever toward the solenoid until it stops, ensuring the actuator rod aligns perfectly with the lever. If misaligned, adjust the rod length by loosening the jam nut and turning the clevis as necessary, then retest the actuator control rod travel. Once correct, tighten the jam nut on the clevis.
