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.

CAUTION: Remove the drain plug caretuly white theengino is hot; the hot oil may cause scalding.
1. Warm up the engine.
2. Drain the engine oil.

3. Reinstall the drain bolt with a new washer, and refill
with the recommended oil.

Every 7,500 miles (12,000 km) or12 months (Normal conditions)
Every 3,750 miles (6,000 km) or 6months (Severe conditions).
NOTE: Under normal conditions, the oil filtershould be replaced at every other oil change. Undersevere conditions, the oil filter should be replacedat each oil change.

Check for continuity between the positive terminal
and the engine {ground). There should be continuity
with the engine stopped. There should be no conti-

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:
Engino Oil Temperature: 176'F (80'C)
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgt/cm', 10 psil
minimum
Ai 3,000 rpm: 3/r0 kPa {3.5 kgt/cm', 50 psi)
minimum
lf oil pressure in not within specifications, inspect the
oil pump (see page 8-9).

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.

COOLANT TEMPERATURE
Coolant Temperature Sending Unit
Testing
1. Disconnect the YEUGRN wire from the coolant tem
perature sending unit.

2. Using an ohmmeter, measure the change in resis-
tance between the positive terminal and the engine
(ground) with the engine cold and with the engine
at operating temPerature.

3. lf the readings are substantially different from the
specitications above, inspect the coolant level and
the cooling system. lf the cooling system is OK,
replace the sending unit.
