Cylinder Head Removal

NOTE:
^ Use fender covers to avoid damaging painted surfaces.
^ To avoid damaging the wires and terminals, unplug the wiring connectors carefully while holding the connector portion.
^ Connect the Honda Diagnostic System (HDS) to the data link connector (DLC), and monitor the engine coolant temperature (ECT). To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 100°F (38°C) before loosening the cylinder head bolts.
^ Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact any other wiring or hoses, or interfere with any other parts.
