1. Install the coolant outlet pipe to the cylinder head.
2. Install the engine coolant temperature (ECT) sensor and housing to the rear end of the cylinder head.
3. Install the fuel injector rail to the cylinder head.
4. Install the new cylinder head gasket to the cylinder block. The gasket is marked TOP (1).
5. Install the cylinder head to the cylinder block.

Important: The cylinder head bolts must be torqued in 2 stages, loosened, and then retorqued in 3 stages in order to ensure against compression and coolant leaks.

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.
