Exhaust Gas Recirculation Pipe

Exhaust Gas Recirculation Pipe

Removing


The normal operating temperature of the exhaust gas recirculation valve and pipe is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled.


Do not use air tools when removing the bolts from the intake manifold. The intake manifold is made of plastic and it is critical to remove bolts using hand tools only. The use of air tools can damage the threads of the intake manifold.

- Remove the EGR pipe bolts (3) at the intake manifold.

- Remove the silicone rubber seal from between the intake manifold and EGR pipe (5).






- Remove the EGR pipe bolts (3) at the EGR valve (2).






- Remove the EGR pipe (4).

- Remove and discard the silicone rubber seal (5) between the EGR valve (2) and EGR pipe (4).

Installing


Do not use air tools to install the bolts to the intake manifold. Install the bolts using hand tools only. Tighten all bolts to specifications. The use of air tools can cause the threads of the intake manifold to become stripped.

• Inspect the rubber silicone seal for wear or cracks, replace as necessary. Make sure that the silicone rubber seal is undamaged during installation.

- Install a new silicone rubber seal (5) to intake manifold end of pipe (5), if necessary.

- Place the EGR pipe into position on the engine.

- Install the EGR pipe bolts (3) to the intake manifold. Tighten the bolts to 5.5 Nm (48.5 in lbs).






- Install a new gasket (5) between the EGR valve (2) and the EGR pipe (4).

- Install the EGR pipe bolts (3) to the EGR valve (2). Tighten the bolts to 15 Nm (11 ft lbs).
