Removal

CYLINDER HEAD ASSEMBLY








COMPONENTS

REMOVAL
Engine removal is not required for this procedure.

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 mis-connection.
^ Inspect the timing belt before removing the cylinder head.
^ Turn the crankshaft pulley so that the No. 1 piston is at top dead center.
