To install:
  1. Clean all mating surfaces and lightly oil all bolt and stud threads prior to installation.
  2. Place the exhaust manifold into position on the cylinder head using a new gasket. Tighten the four exhaust manifold retaining bolts and two stud bolts to 15-18 ft. lbs. (20-25 Nm).
  3. Install the exhaust pipe to the exhaust manifold and tighten the exhaust pipe attaching nuts to 25-34 ft. lbs. (34-47 Nm).
  4. Install the oil level indicator tube. Tighten the bracket nut to 12-15 ft. lbs. (16-20 Nm). Reposition the engine control sensor wiring.
  5. Connect negative battery cable.
  6. Run the engine and check for exhaust leaks and proper operation.
