- Apply the parking brake.
- Raise the front of the vehicle approximately 100mm (4 in.) with a floor jack. Refer to Lifting and Jacking the Vehicle in General Information.
- Remove the two front frame bolts.
- Slowly lower the frame and powertrain approximately 100mm (4 in.) from the underbody rails in order to gain access to the EGR pipe.
- Place two jack stands beneath the frame to prevent any movement of the frame and powertrain assembly.
- Remove the EGR pipe bolt and the EGR pipe from the EGR valve.
- Loosen the EGR pipe nut in order to remove the EGR pipe from the exhaust manifold.
- Remove the EGR pipe.
Important: Do not lower the frame and powertrain more than 100mm (4 in.)
Installation Procedure
- Install the EGR pipe to the exhaust manifold.
- Install the EGR pipe and the EGR pipe bolt to the EGR valve.
- Use the floor jack in order to raise the frame and powertrain until the frame contacts the underbody rails.
- Install the frame bolts. Refer to Front Frame Replacement in Frame and Underbody.
- Remove the jack stands.
- Lower and remove the floor jack.
- Release the parking brake.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
