1997 TOYOTA TACOMA air condition

143
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine running.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
! 3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain-ing from the air conditioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken of the coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as- sistance.
5. If The engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quick-
ly by running it at about 1500 rpm for
a few minutes with the accelerator
pedal lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out underpressure. CAUTION
!
7. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota deal-
er.

CORROSION
PREVENTION ANDAPPEARANCE CARE
Protecting your Toyota from corrosion
Washing and waxing your
Toyota
Cleaning the interior
Toyota, through its diligent research, de-
sign and use of the most advanced
technology available, has done its part to
help prevent corrosion and has provided you with the finest quality vehicle
construction. Now, it is up to you. Proper
care of
your Toyota can help ensure long-
term corrosion prevention.
The most common causes of corro-
sion to your vehicle are: The accumulation of road salt, dirt and
moisture in hard-to-reach areas un- der the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmentalconditions: Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea-
coast or in areas of industrial pollution.
High humidity accelerates corrosion
especially when temperatures rangejust above the freezing point.
Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High temperatures will cause corro-
sion to those components of the ve-
hicle which are prevented from quick-
drying due to lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside,
as clean as possible and to repair any
damage to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently: It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent corrosion, the following points should beobserved: If you drive on salted roads in the win-
ter or if you live near the ocean, you
should hose off the undercarriage atleast once a month to minimize corro- sion.

162
High pressure water or steam is effec-
tive for cleaning the vehicle's under-
side and wheel housings. Pay particu-
lar attention to these areas as it is
difficult to see all the mud and dirt. It
will do more harm than good to simply
wet the mud and debris without remov-
ing them. The lower edge of doors,
rocker panels and frame members
have drain holes which should not be
allowed to clog with dirt as trapped wa-
ter in these areas can cause corrosion.
Wash the underside of the vehicle
thoroughly when winter is over.
See Washing and waxing your Toyotaº
for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im- mediately to prevent corrosion from start- ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair. Check the interior of your vehicle.
Wa-
ter and dirt can accumulate under the floor
mats and could cause corrosion. Occa-
sionally check under the mats to make sure the area is dry. Be particularly careful
when transporting chemicals, cleansers,
fertilizers, salt, etc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full- size shields, which come as near to the
ground as possible, are the best. We rec-
ommend that the fittings and the area
where the shields are installed be treated
to resist corrosion. Your Toyota dealer will
be happy to assist in supplying and instal-
ling the shields if they are recommended for your area.
Do not park your vehicle in a damp, poorly ventilated garage. If you wash
your vehicle in the garage, or if you drive
it in covered with water or snow, your ga- rage may be so damp it will cause corro-
sion. Even if your garage is heated, a wet
vehicle can corrode if the ventilation is
poor. Washing your Toyota by hand
Work in the shade and wait until the ve-
hicle body is not hot to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your hands.!
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or in the wheel
wells.
2. Wash with a mild car-wash soap, mixed according to the manufacturer's
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hard-let the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap or
neutral detergent.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted surfaces.
Do not use gasoline or strong
solvents, which may be toxic or
cause damage.

When cleaning the inside of the
windows, be careful not to scratch
or damage the heater wires on therear window.
NOTICE
Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off any dirt.

Do not use organic substances(solvents, kerosene, alcohol, gas-
oline, etc.) or alkaline or acidicsolutions. These chemicals cancause discoloring, staining or
peeling of the surface.
NOTICE
If you use cleaners or polishingagents, make sure their ingredi-
ents do not include the sub-
stances mentioned above.
If you use a liquid car freshener,do not spill the liquid onto the ve-
hicle's interior surfaces. It maycontain the ingredients men-
tioned above. Immediately clean
any spill using the method men-tioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool. Remove dirt using a soft cloth dampened
with 5 % Solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.

If a stain should fail to come outwith a neutral detergent, apply a
cleaner that does not contain anorganic solvent.
NOTICE
Never use organic substancessuch as benzine, alcohol or gaso-
line, or alkaline or acid solutionsfor cleaning the leather as thesecould cause discoloring.
Use of a nylon brush or synthetic
fiber cloth, etc. may scratch thefine grained surface of the leather.
Mildew may develop on soiled
leather upholstery. Be especiallycareful to avoid oil spots. Try to
keep your upholstery alwaysclean.
Long exposure to direct sunlightmay cause the leather surface to harden and shrink. Keep your ve-hicle in a shaded area, especially
in the summer.
The interior of your vehicle is aptto heat up on hot summer days, so
avoid placing on the upholsteryitems made of vinyl or plastic orcontaining wax as these tend to
stick to leather when warm.
Improper cleaning of the leatherupholstery could result in discol-
oration or staining.

mech-
anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector lever in ºPº position and all brakes re- leased.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time , e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.
Engine coolant level Make sure the coolant level is between
the FULLº and LOWº lines on the see-
through reservoir when the engine is cold.
See Chapter 7-2 for additional informa-tion.
Battery electrolyte level Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information. Brake fluid level
Make sure the brake fluid level is correct. See Chapter 7-2 for additional informa- tion.
Engine oil level
Check the l
evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. SeeChapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when drivingstraight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal
Does your vehicle need repairing?

CAUTION
Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It
can cause dangerous handling
characteristics, resulting in loss of control.
Do not use tire or wheels other than
the manufacturer's recommended size.!
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See If you have a flat tireº in Part 4 for tire
change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
Two-wheel drive models with steel wheels
Two-wheel drive models with alumi-
num wheels and four-wheel drive models To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires every 12000 km (7500
miles).
However, the most appropriate
timing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See If you have a flat tireº in Part 4 for tire
change procedure. When rotating tires, check for even wear
and damage. Abnormal wear is usually
caused by incorrect tire pressure, improp-
er wheel alignment, out-of-balance
wheels, or severe braking.
