Cylinder Head Removal

NOTE:

Use fender covers to avoid damaging painted surfaces.
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 38°C (100°F) before loosening the cylinder head bolts.
Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or hoses, or interfere with other parts.
