Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. NOTICE: Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.

    NOTE: Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.

    Remove the spark plugs.
Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. Remove the retainers and the engine undershield.
Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. NOTE: Measure the valve clearance at base circle, with the lobe pointed away from the tappet, before removing the camshafts. Failure to measure all clearances prior to removing the camshafts will necessitate repeated removal and installation and wasted labor time.

    Measure each valve's clearance and record its location.
    Use the General Equipment: Feeler Gauge
Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. NOTE: The nominal clearance is:

    • intake: 0.0112 in (0.285 mm)
    • exhaust: 0.0167 in (0.425 mm)

    NOTE: The acceptable clearance is:

    • intake: 0.009–0.013 in (0.24–0.33 mm)
    • exhaust: 0.015–0.019 in (0.38–0.47 mm)
    Replace the valve tappets as needed.

Adjustment

  1. Remove the camshafts.
    Refer to: Camshafts (303-01A Engine - 1.5L EcoBoost (118kW/160PS) – I4, Removal and Installation).
  1. NOTE: The number on the valve tappet only reflects the digits that follow the decimal. For example, a tappet with the number '3,125' has the thickness of 3.125 mm.

    NOTE: Select the closest tappet size to the ideal tappet thickness available and mark the installation location.

    Select tappets using this formula: tappet thickness = measured clearance + the existing tappet thickness - nominal clearance.
  1. Install the correct valve tappet.
  1. NOTE: Install a new O-ring seal.

    Install the new O-ring seal.
Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. Apply a 2.0 mm bead of flange sealant.
    Material: Flange Sealant / CU7Z-19B508-A (WSS-M2G348-A11)
Ford Fusion. Valve Clearance Adjustment. General Procedures
  1. NOTE: Make sure that the components are installed to the position noted before removal.

    NOTE: Make sure that new bolts are installed.

    NOTE: Apply clean engine oil to the bearing surfaces of the camshafts, camshaft bearing caps and the VCT bridge.

    Install the camshafts approximately at valve overlap position cylinder No. 4. Install the camshaft caps and tighten the bolts evenly, half turn at a time, until the crankshaft bearing caps and the VCT bridge are seated against the cylinder head.
