REMOVAL

CAUTION
^ Use fender covers to avoid damaging painted surfaces.
^ To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
^ When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
^ To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE
^ Mark all wiring and hoses to avoid misconnection.
^ Turn the crankshaft pulley so that the No. 1 piston is at top dead center.
