Removal
Engine removal is not required for this procedure.
l!@ Make sure iacks and safety stands are
placed properly, and hoist blackels ale attachgd to the
correct position on the engine.
NOTE:
o Use fender covers to avoid damaging painted sur-
faces.
o To avoid damage, unplug the wiring connectors care-
fully while holding the connector portion.
. To avoid damaging the cylinder head, wait until the
engine coolant temperature drops below 100"F (38'C)
before loosening the retaining 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.

Check that the mating surfaces are clean and dry.
Apply liquid gasket, part No. 08718 - 0001 or 08718- 0003, to the head cover gasket at the eight corners
of the recesses.
NOTE:
. Do not install the parts if five minutes or more
have elapsed since applying liquid gasket.
Instead, reapply liquid gasket after removing old
residue.
. After assembly. wait at least 30 minutes before
filling the engine with oil.
Apply liquid gasket tothe shaded areas.
Hold the head cover gasket in the groove by placing
your fingers on the camshaft holder contacting sur-
faces (top of the semicirclesl.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
Inspect the cover washers. Replace any washer that
is damaged or dete(iorated.

Radiator Fan Switch Testing
E@ Removing the radiator fan switch whilethe engine is hot can cause the coolant to spray out, seri-ously scalding you. Always let the enginc and radiatorcool down before removing the radiator fan switch.
1. Remove the radiator fan switch from the thermostathousing (see page 10 '10).
2. Suspend the radiator fan switch in a container ofwater as shown.
Heat the water, and check the temperature with athermometer. Do not let the thermometer touch thebottom of the hot container.
Measure the continuity between the A and B termi-nals according to the table.
Bleed the air from the cooling system after installingthe radiator fan switch (see page 10-5).
