o To avoid damage, unplug the wiling connectors
carefully while holding the connector portion to
avoid damage.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F
{38"C} before loossning the tetaining bolts.
NOTE:
o Mark all wiring and hoses to avoid misconnectlon
Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.
