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.

OIL FILTER WRENCH
8-8
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.

Testing
@G Do not smoke during the test. Keep opon
flames away lrom your work ar€a.
1. Attach a fuel pressure gauge to the service port of
the tuel filter (see page 11-118).
Pr€ssurs should be:

1. Place a shop towel under the fuel pressure regula-
tor, then relieve fuel pressure (see page 11-1'18).
2. Disconnect the vacuum hose and fuel return hose.
3. Remove the.two 6 mm retainer bolts.
NOTE:
. Replace the O-ring.
o When assembling the fuel pressure regulator,
apply clean engine oil to the O-ring and assem-
ble it into its proper position, taking care not to
damage the O-ring.
