surface. When you tighten the filter, rotate it about a
quarter-turn after it contacts the mounting boss (or
Fig. 183 . , , then insert a funnel, and pour
oil directly into the engine
follow any instructions which are provided on the fil-
ter or parts box).
Operating the engine without the proper
amount and type of engine oil will result In
severe engtne damage.
FLUID RECOMMENDATIONS
For all vehicles with manual transaxles, use Hy-
poid gear oil SAE 75W-85W, or 75W-9OW conform-
ing to API specifications GL-4 or higher.
LEVELCHECK
Be careful of the oil; when at operating tem-
perature, it is hot enough to cause a severe
bum.
5. Allow the oil to drain until nothing but a few
drops come out of the drain hole. Check the drain
plug to make sure the threads and sealing surface are
not damaged. Carefully thread the plug into position
and tighten it snug, and give a slight additional turn.
You don't want the plug to fall out (as you would
quickly become stranded), but the pan threads are
EASILY stripped from overtightening (and this can be
time consuming and/or costly to fix).
6. To remove the filter, you may need an oil filter
wrench since the filter may have been fitted too
tightly and/or the heat from the engine may have
made it even tighter. A filter wrench can be obtained
at any auto parts store and is well-worth the invest-
ment. Loosen the filter with the filter wrench. With a
rag wrapped around the filter, unscrew the filter from
the boss on the side of the engine. Be careful of hot
oil that will run down the side of the filter. Make sure
that your drain pan is under the filter before you start
to remove it from the engine; should some of the hot
oil happen to get on you, there will be a place to
dump the filter in a hurry and the filter will usually
spill a good bit of dirty oil as it is removed.
7. Wipe the base of the mounting boss with a
clean, dry cloth. When you install the new filter,
smear a small amount of fresh oil on the gasket with
your finger, just enough to coat the entire contact
8. Remove the jackstands and carefully lower the
vehicle, then IMMEDIATELY
refill the engine
crankcase with the proper amount of oil. DO NOT
WAIT TO DO THIS because if you forget and some-
one tries to start the vehicle, severe engine damage
will occur.
9. Refill the engine crankcase slowly, checking
the level oflen, you may r..':-- U.-1 :L ..-.." II.. .-L-e

less than the amount of oil listed in the capacity chart
to refill the crankcase. But, that is only until the en-
gine is run and the oil filter is filled with oil. To make
sure the proper level is obtained, run the engine to
normal operating temperature, shut the engine OFF,
allow the oil to drain back into the oil pan, and
recheck the level. Top off the oil at this time to the fill
mark.
*If the vehicle Is not resting on level
ground, the oil level reading on the dipstick
may be slightly off. Be sure to check the level
only when the vehicle is sitting level.
10. Drain your used oil in a suitable container for
recycling.
b See Flgures 184 and 185
Inspect each component for leaking. Check the oil
level by removing the filler plug. If the oil is contami-
nated, it is necessary to replace it with new oil. Check
the oil level as follows:
