Procedure

    If not specified apply the following fastener torque specs.

    Size Torque
    6 mm 8 Nm (6 ft-lbs)
    8 mm 20 Nm (15 ft-lbs)
    10 mm 40 Nm (29 ft-lbs)

  1. Ensure that the mating surface on the cylinder head and block are clean. Remove all old gasket material and deposits. Be careful if using a scraper as it can easily gouge the aluminum surfaces of the head and block. Minor scratches can be remove with emery cloth or steel wool. Deep gouges will require machining to keep the mating surfaces level. In the case of the block this could require removing the engine from the car and removing the head studs.
  2. Place the new head gasket on the block..

    NOTE (from Tim Richards)

    I've never tried it personally but, Tim Richards suggests removing the cylinder head with the exhaust manifolds still attached. According to Tim, it saves a couple hours of work. The cylinder head can also be installed with the exhaust manifolds attached. Thanks for the suggestion Tim.

  3. Install the cylinder head onto the block.
  4. Install the two M8 Allen head bolts (6 mm head) at the front of the cylinder head. Tighten the bolts to 20 Nm (15 ft-lbs).
  5. Coat the head stud threads with a light film of engine oil. Do not use anything other than engine oil.
  6. Install all head stud nuts finger tight and then torque in three steps to the appropriate torque for your engine. Refer to CYL-03 for appropriate torque specs for your vehicle and tightening pattern.
  7. Connect the coolant hose at the back of the cylinder head going to the heater control valve.
  8. Connect the coolant outlet hose at the front of the cylinder head.
  9. Place the exhaust manifold in position in the car.
  10. Install the exhaust manifold studs and retaining nuts to secure the exhaust manifolds to the head. Torque the exhaust manifold nuts to 20 Nm (15 ft-lbs).
  11. Using FUEL-09, install the intake manifold.
  12. Using CAM-02, install the camshaft assembly.
  13. Using FUEL-02, install the fuel rail and injectors.
  14. Using the appropriate sections of ENG-06 and ENG-10, install and tension the camshaft belt.
  15. Install the front timing covers.
  16. Using AF-01, install the air filter housing and air flow sensor.
  17. Using IGN-01, install the rotor and distributor cap.
  18. Route coil wire to the distributor and plug wires from the distributor to the spark plugs.
  19. Using COOL-02, fill and vent the coolant system.
  20. Reconnect battery leads.

    NOTE

    After the engine has been run at normal operating temperature, the exhaust manifold retaining nuts should be checked and re-torqued as necessary.
