l The condensation drain tube expels any water
which accumulates on the bottom of the evaporator
housing into the engine compartment. If this tube is
obstructed, the air conditioning performance can be
restricted and condensation buildup can spill over
onto the vehicle’s floor.

operating correctly. Start the engine and warm it to
normal operating temperature, then make sure the

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.

streaking, smearing and blade deterioration if left on
the glass. It is advisable to wash the windshield care-
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.
If your vehicle is equipped with aftermarket blades,
there are several different types of refills and your vehi-

TIRE ROTATION
# See Figures 137 and 138
Tires must be rotated periodically to equalize wear
patterns that vary with a tire’s position on the vehicle.
Tires will also wear in an uneven way as the front

cle might have any kind. Aftermarket blades and arms
rarely use the exact same type blade or refill as the
original equipment. Here are some typiel aftermarket
blades; not all may be available for your vehicle:
The Anco@ type uses a release button that is
pushed down to allow the refill to slide out of the
yoke jaws. The new refill slides back into the frame
,
and locks in place.
Some Trico@ refills are removed by locating where
the metal backing strip or the refill is wider. Insert a
small screwdriver blade between the frame and metal
backing strip. Press down to release the refill from
the retaining tab.
Other types of Trico@’ refills have two metal tabs
which are unlocked by squeezing them together. The
rubber filler can then be withdrawn from the frame
iaws. A new refill is installed bv insertina the refill lowed to touch the olass steering/suspension system wears to the point where
the alianment should be reset.
# See Figure 138
Common sense and good driving habits will af-
ford maximum tire life. Fast starts, sudden stops
and hard cornering are hard on tires and will
shorten their useful life span. Make sure that you
don’t overload the vehicle or run with incorrect
pressure in the tires. Both of these practices will in-
crease tread wear.
*For optimum tire life, keep the fires prop
eriy inflated, rotate them often and have the
wheel alignment checked periodically.
Inspect your tires frequently. Be especially care-
ful to watch for bubbles in the tread or sidewall,
deep cuts or underinflation. Replace any tires with
bubbles in the sidewall. If cuts are so deep that they
penetrate to the cords, discard the tire. Any cut in
the sidewall of a radial tire renders it unsafe. Also
look for uneven tread wear patterns that may indi- Rotating the tires will ensure maximum life for the

jnto the front frame jaws and &ding it rearward to
engage the remaining frame jaws. There are usually
four jaws; be certain when installing that the refill is
engaged in all of them. At the end of its travel, the
tabs will lock into place on the front jaws of the wiper
blade frame.
Another type of refill is made from polycarbonate.
The refill has a simple locking device at one end
which flexes downward out of the groove into which
the jaws of the holder fit, allowing easy release. By
sliding the new refill through all the jaws and push-
ing through the slight resistance when it reaches the
end of its travel, the refill will lock into position.
To replace the Tridon@ refill, it is necessary to re-
move the wiper blade. This refill has a plastic backing
strip with a notch about 1 in. (25mm) from the end.

l Special car washing detergent is the best to
use. Liquid dishwashing detergent can remove wax
and leave the car’s paint unprotected and in addition
some liquid detergents contains abrasives which can
scratch the paint.
l Bird droppings should be removed from the
paintwork as soon as possible, otherwise the finish
may be permanently stained.
When the car is driven immediately after be-
ing washed, apply the brakes several times

On most models, the manufacturer doesn’t install
lubrication fittings on lube points on the steering
linkage or suspension. However, if the lubrication
point does have a grease fitting, lubricate with multi-
purpose NLGI No. 2 (Lithium base) grease.
CAR WASHING
The car should be washed at regular intervals to
remove dirt, dust, insects, and tar and other possibly
damaging stains that can adhere to the paint and may
cause damage. Proper exterior maintenance also
helps in the resale value of the vehicle by maintaining
its like-new appearance.
Mt is particularly important ta frequentiy
wash the car in the wintertime to prevent cor-
rosion, when salt has been used on the roads.
There are many precautions and tips on washing,
including the following:
l When washing the car, do not expose it do di-
rect sunlight.
. Use lukewarm water to soften the dirt before
you wash with a sponge, and plenty of water, to avoid
scratching.
l A detergent can be used to facilitate the soften-
ing of dirt and oil. * A water-soluble grease solvent may be used in
cases of sticky dirt. However, use a washplace with a
drainage separator.
l Dry the car with a clean chamois and remem-
ber to clean the drain holes in the doors and rocker
panels.
l If equipped with a power radio antenna, it must
be dried after washing.
Never clean the bumpers with gasoline or
paint thinner, always use the same agent as
used on the painted surfaces of the vehicle.
l Tar spots can be removed with tar remover or
kerosene after the car has been washed.
l A stiff-bristle brush and lukewarm soapy water
can be used to clean the wiper blades. Frequent
cleaning improves visibility when using the wipers
considerably.
l Wash off the did from the underside (wheel
housings, fenders, etc.).
l In areas of high industrial fallout, more fre-
quent washing is recommended.
During high pressure washing the spray nonle
must never be closer to the vehicle than 13
inches (30cm). Do not spray into the locks.
l When washing or steam cleaning the engine,
avoid spraying water or steam directly on the electri-
cal components or near the distributor or ignition
components. After cleaning the engine, the spark
plug wells should be inspected for water and blown
dry if necessary. Automatic car washing is a simple and quick way
to clean your car, but it is worth remembering that it
is not as thorough as when you yourself clean the
car. Keeping the underbody clean is vitally important,
and some automatic washers do not contain equip-
ment for washing the underside of the car.
When driving into an automatic was, make sure
the following precautions have been taken:
l Make sure all windows are up, and no objects
that you do not want to get wet are exposed.
l In some cases, rotating the side view mirrors
in can help to avoid possible damage.
l If your car is equipped with a power antenna,
lower it. If your vehicle has a solid mounted, non-
power antenna, it is best to remove it, but this is not
always practical. Inspect the surroundings to reduce
the risk of possible damage, and check to see if the
antenna can be manually lowered.
Most manufacturers do not recommend auto-
matic car washing in the first six months due
to the possibility of insufficient paint curing;
a safe bet is to wait until after six months of
ownership (when purchased new) to use an
automatic car wash.
WAXING
eBefore applying wax, the vehicle must be
washed and thoroughly dried.
Waxing a vehicle can help to preserve the appear-
ante of your vehicle. A wide range of polymer-based
car waxes are available today. These waxes are easy
to use and produce a long-lasting, high gloss finish
that protects the body and paint against oxidation,
road dirt, and fading.
Sometimes, waxing a neglected vehicle, or one
that has sustained chemical or natural element dam-
age (such as acid rain) require more than waxing,
and a light-duty compound can be applied. For se-
verely damaged surfaces, it is best to consult a pro-
fessional to see what would be required to repair the
damage.
Waxing procedures differ according to manufac-
turer, type, and ingredients, so it is best to consult
the directions on the wax and/or polish purchased.
