Engine Oil
Inspection
2.
1.Park the vehicle on level ground, and turn off theengine. Allow the oil a few minutes to drain backinto the oil pan so the dipstick will show the actuallevet,
Make certain that the oil level indicated on the dip-stick is between the upper and lower marks. Insertthe dipstick carefully to avoid bending it.
lf the level has dropped close to the lower mark,add oil until it reaches the upper mark.

Remove the YEL/RED wire from the engine oil pres-
sure swrtcn.
Check for continuity between the positive terminal
and the engine {ground). There should be continuity

Start the engine. Shut it off immedjately if the gauge
registers no oil pressure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (fan
comes on at least twice). The pressure should be:

Test the motor by connecting battery power to theNo. 2 terminal and ground to the No. 1 terminal.
lf the motor fails to run or does not run smoothly,reptace rt.

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).

Goolant Temperature Gauge
Gauge Testing
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testin9.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire from the coolant tempera-
ture sending unit. and ground it with a jumper wire.
YEL/GRNWIRE
Turn the ignition switch ON {ll). Check that the
pointer of the coolant temperature gauge starts
moving toward the "H" mark. Turn the ignition
switch OFF before the pointer reaches "H" on the
gauge dial. Failure to do so may damage the gauge.
lf the pointer of the gauge does not move at all,
check for an open in the YEL/GRN wire.
lf the wires are OK, replace the coolant temperature
gauge.
lf the coolant temperature gauge works, test the
coolant temperature sending unit.
