the inner threads of the bolt holes.
NOTE: Do not install the parts if 5 minutes or more
have elapsed since applying liquid gasket. Instead,
reapply liquid gasket after removing old residue.
Installthe oil pan.

Oil Pressure Switch Test
1. Remove the YEURED wire (A)from the engine oilpressure switch (B).
Check for continuity between the positive terminal(C) and the engine (ground). There should be
continuity with the engine stopped. There should
be no continuity with the engine running.
lf the switch fails to operate, check the engine oil
level. lf the engine oil level is OK. check the engine
oil pressure. lf the oil pressure is OK, replace lhe oil
Dressure switch.

Oil Pressure Test
lf the oil pressure indicator stays on with the engine
running. check the engine oil level. lf the oil level is
correct:
Connect a tachometer.
Remove the engine oil pressure switch, and install
an oil pressure gauge {A).

Sta rt the engine. Shut it off immediately if thegauge registers no oil pressure. Repair lhe problem
before continuing.
Allow the engine to reach operating temperature(fan comes on at least twice), The pressure should
be:
Engine Oil Temperature: 176'F (80'Cl
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgf/cm', 10 psi)
mtntmum
At 3,000 rpm: 300 kPa (3.1 kgf/cm',44 psi)

lf the oil pressure is NOT within specifications,
inspect these items:. Check the oil screenforclogging.. Check the oil pump (see page 8-8).. Check crankshaft and connecting rod bearing
clearances.

2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter

5. lf 4 numbers or marks (1 to 4 or V to VVVV) are
printed around the outside of the filter, use the
following procedure to tighten the filter.
. Spin the filter on until its seal lightly seats against
the block, and note which number or mark is at
the bottom.. Tighten the filter by turning it clockwise 3
numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.
