EGR Pipe

The process begins by uninstalling the engine sight shield together with the air intake duct and egr value. The egr pipe must be detached from both intake and exhaust manifolds through fastener removal to separate it from the right Cylinder Head by its mounting fasteners. Position the egr pipe first then fasten it securely to the right Cylinder Head by tightening its mounting fasteners to 50 n.m (37 lb ft). Reposition the egr pipe between the engine manifold components while fastening the Exhaust Manifold connectors to 25 n.m (18 lb ft) then the Intake Manifold fasteners to 12 n.m (106 lb in). Reinstallation requires both the EGR Valve alongside the air intake duct and engine sight shield.

First users need to remove retaining bolts then they need to remove bolt from the right side head before removing Exhaust Manifold nuts. Begin by taking away the egr valve pipe together with its gaskets and then wash the egr valve pipe mounting surfaces free from dirt and debris. Start by placing the replacement gaskets before installing the egr valve pipe according to the fastener notice in service precautions. Apply the retaining bolts before tightening them to 30 n.m (22 lb ft). After installing the right side head bolt with 50 n.m (37 lb ft) torque you must secure the Exhaust Manifold nuts with a torque of 30 n.m (22 lb ft).

The egr pipe replacement process starts by uninstalling the EGR Valve before disconnecting the egr pipe to Intake Manifold fasteners along with the egr pipe to Exhaust Manifold fasteners and the egr pipe mounting fasteners on the right Cylinder Head. The egr pipe can then be removed. Placing the egr pipe requires installation of the egr pipe mounting fasteners to the right Cylinder Head at 50 n.m (37 lb ft). Fasten first the egr pipe to Exhaust Manifold with 25 n.m torque (18 lb ft), then proceed to the egr pipe to Intake Manifold fasteners that require a torque of 12 n.m (106 lb in). Reinstall the EGR Valve after which you need to install the air intake duct.

Service of the EGR Tube requires EGR Valve removal followed by removal of egr pipe to intake manifold fasteners along with the egr pipe to exhaust manifold fasteners and egr pipe mounting fasteners from the right Cylinder Head until the pipe can be extracted successfully. After placing the egr pipe correctly in its position you should tighten the egr pipe mounting fasteners to the right Cylinder Head at 50 n.m (37 lb ft). The egr pipe requires mounting to the exhaust manifold fasteners with a torque of 25 n.m and to the intake manifold fasteners with 12 n.m. Finally, reinstall the EGR Valve.

The replacement process of the exhaust gas recirculation (EGR) pipe requires the removal of engine sight shield and EGR Valve first. First remove all fasteners from the egr pipe leading to both the intake and Exhaust Manifold before detaching the egr pipe from the right Cylinder Head then extract the egr pipe itself. Secure the egr pipe in its position by fastening mounting brackets to the right Cylinder Head while tightening them to 50 n.m (37 lb ft). Mount the egr pipe onto the Exhaust Manifold first before tightening the fasteners to 25 n.m (18 lb ft). Afterward, fasten the egr pipe to the Intake Manifold through adjustments of 12 n.m (106 lb in). The EGR Valve and engine sight shield should be reinstalled after the completion of the procedure.

Take out the bolt from the right side head.
