ion type (which require screw or hex drivers to
oosen). Pull the clamps back on the hose away from
he connection. Never remove the pressure cap while the en-
gine is running, or personal injury from
scalding hot coolant or steam may result. If
possible, wait until the engine has cooled to
remove the pressure cap. If this is not possi-
ble, wrap a thick cloth around the pressure
cap and turn it slowly to the stop. Step back
while the pressure is released from the cool-
ing system. When you are sure all the pres-
sure has been released, use the cloth to turn
and remove the cao.
2. Position a clean container under the radiator
and/or engine draincock or plug, then open the drain
and allow the cooling system to drain to an appropri-
ate level. For some upper hoses, only a little coolant
must be drained. To remove hoses positioned lower
on the engine, such as a lower radiator hose, the en-
tire cooling system must be emptied.
When draining coolant, keep in mind that
cats and dogs are attracted by ethylene gly-
col antifreeze, and are quite likely to drink
any that is left in an uncovered container or
in puddles on the ground. This will prove fa-
tal in sufficient quantity. Always drain
coolant into a sealable container. Coolant
may be reused unless it is contaminated or
several years old. 9. Close the radiator or engine drains and prop-
erly refill the cooling system with the clean drained
engine coolant or a suitable mixture of ethylene gly-
cot coolant and water.
10. If available, install a pressure tester and check
for leaks. If a pressure tester is not available, run the
engine until normal operating temperature is reached
(allowing the system to naturally pressurize), then
check for leaks.
If you are checking for leaks with the system
at normal operating temperature, BE EX-
TREMELY CAREFUL not to touch any moving
or hot engine parts. Once temperature has
been reached. shut the enaine OFF. and

The CV (Constant Velocity) boots should be
checked for damage each time the oil is changed and
any other time the vehicle is raised for service. These
boots keep water, grime, dirt and other damaging
matter from entering the CV-joints. Any of these
could cause early CV-joint failure which can be ex-
pensive to repair. Heavy grease thrown around the in-
side of the front wheel(s) and on the brake
caliper/drum can be an indication of a torn boot.

For maximum effectiveness and longest element
Although the A/C system should not be serviced
by the do-it-yourselfer, preventive maintenance can
be practiced and A/C system inspections can be per-
formed to help maintain the efficiency of the vehicle’s
A/C system. For A/C system inspection, perform the
following:
The easiest and often most important check for the
air conditioning system consists of a visual inspec-
tion of the system components. Visually inspect the
air conditioning system for refrigerant leaks, dam-
aged compressor clutch, abnormal compressor drive
belt tension and/or condition, plugged evaporator
drain tube, blocked condenser fins, disconnected or
broken wires, blown fuses, corroded connections and
poor insulation.
A refrigerant leak will usually appear as an oily
residue at the leakage point in the system. The oily
residue soon picks up dust or dirt particles from the
surrounding air and appears greasy. Through time,
this will build up and appear to be a heavy dirt im-
pregnated grease.
For a thorough visual and operational inspection,
check the following: * Check the surface of the radiator and con-
denser for dirt, leaves or other material which might
block air flow.
l Check for kinks in hoses and lines. Check the
system for leaks.
l Make sure the drive belt is properly tensioned.
When the air conditioning is operating, make sure the
drive belt is free of noise or slippage.
l Make sure the blower motor operates at all ap-
propriate positions, then check for distribution of the
air from all outlets with the blower on HIGH or MAX.
*Keep in mind that under conditions of high
humidity, air discharged from the A/C vents
may not feel as cold as expected, even if the
system is working properly. This is because
vaporized moisture in humid air retains heat
more effectively than dry air, thereby making
humid air more difficult to cool.

fully with a commercial glass cleaner at least once a
month. Wipe off the rubber blades with the wet rag
afterwards. Do not attempt to move wipers across the
windshield by hand; damage to the motor and drive
mechanism will result.
To inspect and/or replace the wiper blade ele-
ments, place the wiper switch in the LOW speed po-
sition and the ignition switch in the ACC position.
When the wiper blades are approximately vertical on
the windshield, turn the ignition switch to OFF.
Examine the wiper blade elements. If they are
found to be cracked, broken or torn, they should be
replaced immediately. Replacement intervals will vary
with usage, although ozone deterioration usually lim-
its element life to about one year. If the wiper pattern
is smeared or streaked, or if the blade chatters across
the glass, the elements should be replaced. It is easi-
est and most sensible to replace the elements in
pairs.

GENERALINFORMATIONAND MAINTENANC-E 1133
Used fluids such as engine oil, transaxle fluid, an-
tifreeze and brake fluid are hazardous wastes and
must be disposed of properly. Before draining any
fluids, consult with your local authorities; in many ar-
eas, waste oil, antifreeze, etc. is being accepted as a
part of recycling programs. A number of service sta-
tions and auto parts stores are also accepting waste
fluids for recycling.
Be sure of the recycling center’s policies before
draining any fluids, as many will not accept different
fluids that have been mixed together.
ENGINE OIL
6 See Figure 148
WMitsubishi recommends that SAE 5W-30
viscosity engine oil should be used for all clia
mate conditions, however, SAE low-30 is ac
ceptable for vehicles operated in moderate-
to-hot climates. the SAE number, the lighter the oil; the lower the vis-
cosity, the easier it is to crank the engine in cold
weather but the less the oil will lubricate and protect
the engine in high temperatures. This number is
marked on every oil container.
Oil viscosity’s should be chosen from those oils
recommended for the lowest anticipated temperatures
during the oil change interval. Due to the need for an
oil that embodies both good lubrication at high tem-
peratures and easy cranking in cold weather, multi-
grade oils have been developed. Basically, a multi-
grade oil is thinner at low temperatures and thicker at
high temperatures. For example, a low-40 oil (the W
stands for winter) exhibits the characteristics of a 10
weight (SAE 10) oil when the car is first started and
the oil is cold. Its lighter weight allows it to travel to
the lubricating surfaces quicker and offer less resis-
tance to starter motor cranking than, say, a straight
30 weight (SAE 30) oil. But atier the ensine reaches
operating temperature, the low-40 oil begins acting
like straight 40 weight (SAE 40) oil, its heavier weight
providing greater lubrication with less chance of
foaming than a straight 30 weight oil. Synthetic oil is not for every car and every type of
driving, so you should consider your engine’s condi-
tion and your type of driving. Also, check your car’s
warranty conditions regarding the use of synthetic oils.
FUEL
All models equipped with a SOHC (Single Over-
head Camshaft) engine are designed to operate using
regular unleaded fuel with a minimum of 87 octane.
All models equipped with a DOHC (Dual Overhead
Camshaft) engine are designed to operate using reg-
ular unleaded fuel with a minimum of 91 octane. Mit-
subishi warns that using gasoline with a lower octane
rating can cause persistent and heavy knocking, and
may cause internal engine damage.
If your vehicle is having problems with rough idle
or hesitation when the enoine is cold, it mav be
caused by low volatility fuel. If this occurs, iry a dif-
ferent grade or brand of fuel.

Synthetic Oil
There are many excellent synthetic and fuel-effi-
cient oils currently available that can provide better
gas mileage, longer service life and, in some cases,
better engine protection. These benefits do not come
without a few hitches, however; the main one being
the price of synthetic oil, which is significantly more
expensive than conventional oil.

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.

allow the oil to drain back into the oil pan, and
recheck the level. Top off the oil at this time to the fill
