(P/N: 23537846) INSTALLATION PROCEDURE Remove the existing coolant and oil lines as follows:

HOT COOLANT To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure. 1. Drain the coolant completely.

2. Cut the tie straps securing the electrical wires to the oil drain tube. 3. Remove only the upper oil drain tube from the bottom of the turbo and set aside. 4. Remove and discard the coolant supply line going to the actuator. 5. Remove and discard the 90 degree elbow from the actuator. 6. Remove and discard the oil supply line at the bottom of the turbo. Save the P-clip from the line to be reused on the new line. 7. Remove and discard the coolant supply line from the oil cooler housing to the turbocharger. 8. Remove and discard the T-fitting from the bottom of the turbocharger. See Figure 1.

Figure 1 Current Routing Configuration 9. Remove and discard the straight fitting from the oil cooler housing for the coolant line. Install the new coolant and oil lines for the turbocharger as follows: 1. Install new coolant T-fitting (P/N: 23535461) into the oil cooler housing leaving the jam nut

loose. Orientate the side port so it is pointing to the front of the engine. See Figure 2. 2. Install a new straight fitting (P/N: 5319974072) into the bottom of the turbo and torque the

fitting to 34 N·m (25 lb·ft). 3. Install the new coolant supply (P/N: 23537832) to the fitting on the bottom of the turbo and

to the top of the T-fitting. Verify that the line is in front of the EGR cooler tube. See Figure 2.

jam nut loose. 5. Install the new coolant line (P/N:23537833) on the side of the T-fitting and to the 90 degree

fitting. See Figure 2. 6. Using a wrench on the 90 degree fitting (P/N: 23537216) to hold the fitting as not to stress

the line, torque the jam nut on the 90 degree fitting to 22 N·m (16.2 lb·ft). 7. Using a wrench on the T-fitting to hold it as not to stress the lines, torque the jam nut to

22 N·m (16.2 lb·ft). 8. Torque the coolant line (P/N: 23537833) fittings to 36-44 N·m (26.5 – 32.5 lb·ft).

See Figure 2. 9. Torque the coolant line (P/N: 23537832) to 34 N·m (25 lb·ft). See Figure 2. 10. Install the P-clip onto the new oil supply line (P/N: 23537831). Install the new line on the

correct fitting on the engine and the turbo. Torque the fittings to 36-44 N·m (26.5 – 32.5 lb·ft). Tighten the screw holding the P-clip to the mounting bracket. See Figures 3 and 4.

30-38 N·m (22.1 – 28.0 lb·ft). 12. Install new tie straps (P/N: 05101020) for the electrical wires. Locate the tie straps just

above and below the hose clamps on the oil drain tube for the turbocharger. Verify that the wires are also in the clips on the actuator. See Figure 5.

ELECTRICAL SHOCK To avoid injury from electrical shock, do not touch battery terminals, alternator terminals, or wiring cables while the engine is operating. 13. Verify that there are no lines or electrical wires touching any components that could damage

them. See Figure 6.

ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.

14. Fill coolant system to the proper level, warm the engine and recheck the coolant level.

Check for oil and coolant leaks before releasing the truck. ADDITIONAL INFORMATION/NOTES This condition only exists for engines built with the 06M07C-6469 Turbocharger Group. The turbocharger that is used in the identified group is P/N: 23536802 and is also identified by a vertical orientation of the actuator.
