Oil Seals
lnstallation
NOTE:
. Engine removal is not required.
. The crankshaft oil seal housing should be dry.
Apply a light coat of grease to the crankshaft and to
the lips of the seals.
1. Using the special tool, drive in the timing pulley-
end seal until the driver bottoms against the oil
pump.
When the seal is in place, clean any excess grease
off the crankshaft and check that the oil seal lip is
not distorted.

2. Measure the flvwheel-end seal thickness and the oil
seal housing depth. Using the special tool. drive the
flywheel-end seal into the rear cover to the point
where the clearance between the bottom of the oil
seal and the right side cover is 0.5 - 0.8 mm (0.02 -
0.03 in) (see page 7-23).
NOTE: Align the hole in the driver attachment with
the Din on the crankshaft.

Engine Oil
Inspection
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 actuallevel.
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: lmert thc dipstick car€fully to avoid b€nd_ing it.

3. Reinstall the drain bolt with a new washer. and rbfill
the engine with the recommended oil.
NOTE: Under normal conditions, the oil filter should be
replaced at every other oil change Under severe condi-
tions, the oilfilter should be replaced at each oil change'
The numbers in the middle of the API Service label tell
you the oil's SAE viscosity or weight Select the oil for
vour car according to this chart:
30 20 -10 010 20 30 4OoC
An oil with a viscosity of 5W - 30 is preferred for
improved tuel economy and year-round protection in the
car. You may use a 10W - 30 oil if the climate in your area
is limited to the temperature range shown on the chart'

Oil Filter
Replacement
After the engine has been run, the exhaust pipe willbe hot; be careful when working around ihe exhaustpipe.
Be careful when loosening the drain bolt whils theengine is hot. Burns can resuh because the oil tem-peratu16 is very high.
Remove the oil filter with the oil filter wrencn.
Inspect the threads and rubber seal on the new filter.Wipe off the seat on the engine block, then apply alight coat of oil to the new filter,s rubber seal.
NOTE: Use onty fitters with a built-in bypass sys,tem.
Apply oil to rubber sealbefore installing.
l.
Inspect threads andrubber seal surface.

Install the oil filter by hand.
After the rubber seal seats, tighten the oil filter clock_wise with the oil filter wrench.
Tighten: 7/8 tu.n clockwise.
Tightening tolque: 22 N.m (2.2 kgt.m, 16lbf.ft)
OIL FILTER WRENCH07912 - 6110001

Oil Pressure
Use this procedure to tighten the filter if eight num-
bers (1 to 8) are printed on the surface of the filter.
1) Make a mark on the oil filter base under the num-
ber that shows at the bottom of the filter when
the rubber seal is seated.
2l Tighten the filter by turning it clockwise seven
numbers from 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'

CAUTION: Using any procedure other than those
shown could rosult in serious engins damage due
to oil leakage
5. After installation. fill the engine with oil up to the spec-
ified level, run the engine for more than three minutes,
then check for oil leakage

Testing
lf the oil pressure warning Iight stays on with the engine
running, check the engine oil level. It the oil level is cor-
rect:
1. Connect a tachometer'
2. Remove the engine oil pressure switch, and install an
oal pressure gauge.

{CommerciallY availablei
Start the engine. Shut it off immediately if the gauge
registers no oil pr€ssure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (tan
comes on at least tlivice). The pressure should be;
Engine Oil Temperature: 176"F (80"C1
Engine Oil Pressulo:
At ldle: 69 kPa (0.7 kgf/Gm'. 10 Psi)

. lf the oil Dressure is within specifications, replace
the oil pressure switch and recheck.
. lf the oil pressure is NOT within specifications,
inspect the oil pump (see page 8-10).
