      Note


      • Cylinder head sub-assembly warpage or cracking could result from removing bolts in the incorrect order.

      • Be careful not to drop the cylinder head set bolt spacers into the cylinder head sub-assembly.

    2. Lift the cylinder head sub-assembly from the ring pins on the cylinder block sub-assembly, and place the cylinder head sub-assembly on wooden blocks on a bench.

      Note

      Be careful not to damage the contact surfaces of the cylinder head sub-assembly and cylinder block sub-assembly.

      Tech Tips

      If the cylinder head sub-assembly is difficult to remove, use a screwdriver to pry between the cylinder head sub-assembly and cylinder block sub-assembly.

  6. REMOVE CYLINDER HEAD GASKET


    1. Remove the cylinder head gasket from the cylinder block sub-assembly.

  7. INSPECT CYLINDER HEAD SET BOLT


    1. w/ Washer:

        Text in Illustration
        *a Measuring Area
        *b Washer

        Using a vernier caliper, measure the thread outside diameter of the cylinder head set bolt.

        Minimum diameter
        11.4 mm (0.449 in.)

        If the diameter is less than the minimum, replace the cylinder head set bolt.

    2. w/o Washer:


      1. B007RS4E01
        Text in Illustration
        *a Measuring Area

        Using a vernier caliper, measure the thread outside diameter of the cylinder head set bolt.

        Minimum diameter
        12.8 mm (0.504 in.)

        If the diameter is less than the minimum, replace the cylinder head set bolt and cylinder head set bolt spacer.
