Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Important: Note the orientation of the EGR valve at the BASE before removing. Do not use the electrical connector as an indication of valve orientation. It is possible to install this EGR valve backwards. An EGR valve installed backwards may cause a rough idle and set DTCs.

Important: Ensure the EGR valve is oriented in the proper direction.

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.

Tighten
First tighten the bolts to 10 N·m (89 lb in), and then tighten the bolts to 25 N·m (18 lb ft).
