10. Use the J 36660-A , in order to install the bolts. Tighten • Tighten the camshaft housing to cylinder head bolts to 15 N·m (11 lb ft) + 90 degrees. • Tighten the camshaft housing cover to camshaft housing bolts to 15 N·m (11 lb ft) + 30 degrees. 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. 11. Install the timing chain housing to camshaft housing and the timing chain. Refer to Timing Chain Housing Replacement . 12. Install the exhaust camshaft housing cover and the new gasket. 13.

Install the electrical connector to the ignition coil and the module assembly. 21. Connect the negative battery cable. Important: Do not compress the lifter plungers using a vise or other tool. This will cause more air to enter the lifter assembly and will take more time to bleed out once the lifters are installed. 22. If new lifters have been installed or the lifters bled down while the engine was disassembled excessive lifter noise may be experienced. This is a normal condition and no engine damage is occurring. Use the following procedure in order to purge the air from the lifters: 22.1. Start the engine and allow to warm up at the idle for 5 minutes. 22.2. Increase the engine speed to 2000 RPM until the lifter noise is gone. 22.3. Return the engine to idle for an additional 5 minutes or perform a road test. 23. Start the engine and inspect for leaks.
