- Install the EGR inlet pipe into the RH exhaust manifold as the EGR valve adapter assembly is installed onto the cylinder head.
- Install the EGR valve adapter assembly to cylinder head bolts and the EGR inlet pipe to RH exhaust manifold bolt.
- Install the EGR valve outlet pipe to the lower intake and the EGR valve adapter assembly.
- Install the EGR valve outlet pipe bolt and nut.
- Install the EGR valve gasket and EGR valve.
- Install the EGR valve nuts.
- Install the exhaust manifold heat shield.
- Install the exhaust manifold heat shield bolts.
- Install the heated oxygen sensor.
Important: Inspect the exhaust gas recirculation (EGR) inlet/outlet pipes for leaks before installation. If cracks, deformations or any visible signs of leaking are present, replace the appropriate part.
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.
