EGR Cooler Coolant Supply Line • For Rear Gear Train engines, if disassembled, assemble the EGR cooler supply line onto the EGR cooler and install the EGR cooler assembly. Refer to Procedure 011-019. • Install and connect the EGR cooler coolant supply line to the cylinder head coolant fitting. Secure the hose clamps to… Read More »
Clean the tubes with solvent and dry with compressed air. Inspect the tubes for cracks or leaks. Replace any damaged components. Inspect the sealing o-ring for cracks or distortion, replace as necessary. NOTE: If the EGR cooler coolant inlet tube shows signs of leaking, inspect both the sealing o-ring and the EGR coolant inlet bore… Read More »
EGR Cooler Coolant Return Line • Remove the nut from the studded capscrew on the oil cooler housing. • Remove the hose clamps from the EGR cooler coolant return line and remove the return line. EGR Cooler Coolant Supply Line NOTE: In some applications, it is necessary to loosen or remove the EGR cooler to… Read More »
Install the EGR cooler bracket and capscrew to the cylinder head. Tighten the capscrews in the order shown. Torque Value: 24 N•m [ 212 in-lb ] NOTE: It is important to tighten the capscrews in the proper sequence, or the EGR cooler will align incorrectly with the exhaust manifold potentially causing premature EGR cooler malfunction.… Read More »
Clean the EGR cooler bracket with solvent and dry with compressed air. Inspect the EGR cooler bracket for cracks or other damage. Replace the EGR cooler bracket if damaged.
Remove the two capscrews that attach the EGR cooler bracket to the cylinder head. Remove the EGR cooler bracket.
NOTE: Install a light coating of high temperature anti- seize compound to the threads of the exhaust gas pressure sensor tube prior to installation. Install the exhaust gas pressure sensor tube to the port on the exhaust manifold and to the exhaust gas pressure sensor mounting pedestal. Make sure both fittings are hand tight prior… Read More »
Clean the exhaust gas pressure sensor tube with solvent and dry with compressed air. Inspect the tube for signs of leakage, damaged sealing areas, or plugging with soot. If the tube is plugged with soot, use solvent and a pipe cleaner, or similar device, to remove the soot blockages in the tube. For rear gear… Read More »
Remove the mounting fastener securing the exhaust gas pressure sensor tube to the EGR cooler mounting bracket. Use compressed air to clean around the fittings where the exhaust gas pressure sensor tube connects to the exhaust gas pressure sensor and the exhaust manifold. Disconnect the exhaust gas pressure sensor tube from the exhaust gas pressure… Read More »
Inspect the ports on the exhaust manifold and the exhaust pressure sensor for signs of leaks or damage. Leaks can be identified by soot streaks. If leaks are found, tighten the fittings again. If the fittings are not loose, replace the exhaust gas pressure sensor tube.
