Inspection
Park the vehicle on level ground, and turn ofl the
engine. Allow the oil a few minutes to drain back
into the oil pan so the dipstick will show the actual
tevet,
Make certain that the oil level indicated on the dip-
stick is between the upper and lower marks.
lf the level has dropped close to the lower mark,
add oil until it reaches the upper mark.
CAUTION: Insert the dipstick caretully to avoid
bending it.

Ambi€nt Temperature
An oil with a viscosity of 5 W 30 is preferred forimproved fuel economy and year-round protection inthe vehicle.
You may use a 10 W 30 oil if the climate in your area islimited to the temperature range shown on the chart.
4. Run the engine for more than three minutes, thencheck for oil leakage and oil level.

Eight numbers (1 to 8) are printed on the surlace ol
the filter.
The lollowing explains the procedure for tightening
filters using these numbers.
1) Make a mark on the engine oil cooler (818c5
engine) or cylinder block (8188'1, 818C1 engines)
under the number that shows at the bottom of
the filter when the rubber seal is seated.
2) Tighten the filter by turning it clockwise seven
numbers Irom the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point

5. After installation, fill the engine with oil up to the
specilied level, run the engine for more than 3 min-
utes, then check for oil leakage and oil level.
CAUTION: Installation using other than the above
procedure could result in serious engine damage
duo to oil leakage.

Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. It the oil level iscorrect:
Connect a tachometer.
Remove the oil pressure switch and install an oil pressure gauge.
Start the engine. Shut it off immediately if the gaugeregasters no oil pressure. Repair the problem beforecontinuing.
Allow the engine to reach operating temperature (fan
comes on at least twicel. The pressure should be:
Engine Oil Pressure:
At ldle: 70 kPa {O.7 kgficmr, tO psil
minimum
At 3,OOO rpm: 34O kPa (3.5 kgf/cmr, 50 psil
minimum
a lf oilpressure is within specifications, replace theengine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications,rnspect the oil pump (see page g-11).

Oil Jet
lnspection(818C1, 818C5 engines
only)
1. Remove the oil jet (see pages 8 4 or 8 5) and inspectit as follows.
a Make sure rhat a 1 .1 mm (O.04 in) diameter drillwillgo through the nozzle hole fl.2 mm (O.O5 in)diameter).
a Insert the other end of the same 1 .1 mm {0.O4in) drill into the oit intake (1.2 mm (0.05 in)diameter).
Make sure the check ball moves smoothly and hasa stroke of approximately 4.0 mm (O.16 in).a Check the oil jet operation with an air nozzle. ltshould take at least 2OO kPa 12.O kg|lcm2, 2gpsi) to unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzleis damaged or bent.
2. Mounting torque is critical. Be very precise when in-stalling.
