      Seal packing

      Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent

      Standard seal dimension

      3.0 to 7.0 mm (0.118 to 0.276 in.) wide and 3.0 mm (0.118 in.) thick

      Note:
      • Remove any oil from the contact surface.

      • Install the cylinder head gasket within 3 minutes and tighten the bolts within 15 minutes after applying seal packing.

      Tip:

      Apply at least 20 mm (0.787 in.) of seal packing from the inside edge of the protrusion of the cylinder block.

    3. Place a new cylinder head gasket on the cylinder block surface with the front face of the Lot No. stamp upward.

      Note:

      Pay attention to the installation direction.

  2. INSTALL CYLINDER HEAD SUB-ASSEMBLY

    Tip:

    Perform "Inspection After Repairs" after replacing the cylinder head sub-assembly.

    1. Place the cylinder head sub-assembly on the cylinder block.

      Note:
      • Make sure that no oil is on the mounting surface of the cylinder head sub-assembly.

      • Place the cylinder head sub-assembly on the cylinder block gently in order not to damage the gasket with the bottom part of the head.

      Tip:

      The cylinder head set bolts are tightened in 4 progressive steps.

    2. Install the plate washers to the cylinder head set bolts.

    3. Apply a light coat of engine oil to the threads and under the heads of the cylinder head set bolts.

    4. Step 1:

      1. A284098N03

        Using a 10 mm bi-hexagon wrench, install and uniformly tighten the 10 cylinder head set bolts in several steps in the sequence shown in the illustration.

        Note:

        Do not drop the plate washers for the cylinder head set bolt into the cylinder head sub-assembly.

    5. Step 2:

      1. Tighten the cylinder head set bolts again in the sequence shown in the illustration to make sure that they are tightened to the specified torque.

    6. Step 3:

      1. Mark the front side of each cylinder head set bolt head with paint.

      2. Tighten the cylinder head set bolts 90° in the sequence shown in step 1.

    7. Step 4:

      1. Tighten the cylinder head set bolts another 90° in the sequence shown in step 1.

      2. Check that the paint marks are now at a 180° angle to the front.

        Note:
        • Do not apply oil for at least 4 hours after the installation.

        • Do not start the engine for at least 4 hours after the installation.

        • After the installation, if the seal packing has seeped out, wipe it off.
