Cylinder Head: Removal

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  1. Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. 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 bolt. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.
  2. 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.
  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
  2. Release the fuel system pressure. For additional information, refer to FUEL SYSTEM PRESSURE RELEASE .
  3. Drain the engine cooling system. For additional information, refer to DRAINING .
  4. Remove the timing drive components. For additional information, refer to TIMING DRIVE COMPONENTS .
  5. Remove the special tool.
