Removal

CAUTION:
CAUTION:During engine repair procedures, cleanliness is extremely important. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages, coolant passages or the oil pan can cause engine failure.
CAUTION:
CAUTION:The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore, the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Section 100-02 Jacking and Lifting.
  1. Release the fuel system pressure. For additional information, refer to Section 310-00 Fuel System - General Information.
  1. Drain the engine cooling system. For additional information, refer to Section 303-03 Engine Cooling.
  1. Remove the timing drive components. For additional information, refer to Timing Drive Components in this section.

  1. Remove the special tool.

  1. Mark the position of the camshaft lobes on the No. 1 cylinder for installation reference.

  1. CAUTION:
    CAUTION:Failure to follow the camshaft loosening procedure can result in damage to the camshafts.
    Remove the camshafts from the engine.
    • Loosen the camshaft bearing cap bolts, in sequence, one turn at a time until all tension is released from the camshaft bearing caps.
    • Remove the bolts and the camshaft bearing caps.
    • Remove the camshafts.
  1. CAUTION:
    CAUTION:If the camshafts and valve tappets are to be reused, mark the location of the valve tappets to make sure they are assembled in their original positions.
    Remove the valve tappets.
  1. NOTE:
    NOTE:The number on the valve tappets only reflects the digits that follow the decimal. For example, a tappet with the number 0.650 has the thickness of 3.650 mm.
    Inspect the valve tappets. For additional information, refer to Section 303-00 Engine System - General Information.
  1. Remove the intake manifold. For additional information, refer to Intake Manifold in this section.
  1. Remove the exhaust manifold. For additional information, refer to Section 309-00 Exhaust System.
  1. Disconnect the radio ignition interference capacitor electrical connector.
  1. Disconnect the exhaust gas recirculation (EGR) valve electrical connector.
  1. Disconnect the EGR coolant hose from the EGR valve.
  1. Disconnect the upper radiator hose, coolant bypass hose, heater hose and coolant vent hose from the engine coolant outlet.
  1. Remove the bolts and the cylinder head.
    • Discard the bolts and the cylinder head gasket.

Installation

  1. CAUTION:
    CAUTION:Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
    CAUTION:
    CAUTION:Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
    NOTE:
    NOTE:If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
    Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block.
    1. Remove any large deposits of silicone or gasket material with a plastic scraper.
    1. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
    1. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
    1. Apply metal surface prep, following package directions, to remove any traces of oil or coolant, and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
  1. Inspect the cylinder head for distortion. For additional information, refer to Section 303-00 Engine System - General Information.

  1. Apply silicone gasket and sealant to the locations shown.
  1. Install a new head gasket.

  1. NOTE:
    NOTE:The cylinder head bolts are torque-to-yield and must not be reused. New cylinder head bolts must be installed.
    NOTE:
    NOTE:Lubricate the bolts with clean engine oil prior to installation.
    Install new cylinder head bolts. Tighten the bolts in the sequence shown in 5 stages:
    • Stage 1: Tighten to 5 Nm (44 lb-in).
    • Stage 2: Tighten to 15 Nm (11 lb-ft).
    • Stage 3: Tighten to 45 Nm (33 lb-ft).
    • Stage 4: Turn 90 degrees.
    • Stage 5: Turn an additional 90 degrees.
  1. Connect the upper radiator hose, coolant bypass hose, heater hose and coolant vent hose to the engine coolant outlet.
  1. Connect the EGR coolant hose to the EGR valve.
  1. Connect the exhaust gas recirculation (EGR) valve electrical connector.
  1. Connect the radio ignition interference capacitor electrical connector.
  1. Install the exhaust manifold. For additional information, refer to Section 309-00 Exhaust System.
  1. Install the intake manifold. For additional information, refer to Intake Manifold in this section.

  1. NOTE:
    NOTE:Lubricate the valve tappets with clean engine oil.
    Install the valve tappets in their original positions.

  1. CAUTION:
    CAUTION:Install the camshafts with the alignment notches in the camshafts lined up so the camshaft alignment plate can be installed. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Failure to follow this procedure can cause severe damage to the valves and pistons.
    NOTE:
    NOTE:Lubricate the camshaft journals and bearing caps with clean engine oil.
    Install the camshafts and bearing caps. Tighten the bolts in the sequence shown in 3 stages.
    • Stage 1: Tighten the camshaft bearing cap bolts, one turn at a time, until finger tight.
    • Stage 2: Tighten the bolts to 7 Nm (62 lb-in).
    • Stage 3: Tighten the bolts to 16 Nm (12 lb-ft).

  1. Install the special tool.
  1. Install the timing drive components. For additional information, refer to Timing Drive Components in this section.
  1. Fill and bleed the engine cooling system. For additional information, refer to Section 303-03 Engine Cooling.
