1996 TOYOTA TACOMA engine

121
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless
you are sure that the booster batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in
another vehicle, make sure the vehicles
are not touching. Turn off all unnecessary
lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged batter- ies. Lay a cloth over the open vents on the
batteries. (This helps reduce the explo-
sion hazard, personal injuries and burns.)
3. If the engine in the vehicle with the booster battery is not running, start it and
let it run for a few minutes. During jump
starting, run the engine at about 2000 rpm
with the accelerator pedal lightly de- pressed. 4. Connect
the jumper cables in the exact
order shown in the illustration: positiveterminal (+º mark)-to-positive terminal
(+º mark), and negative terminal (-º
mark)-to-engine or body ground. Note
that you first connect the positive cable to
the discharged battery and then to the
booster battery. Next, connect the nega-
tive cable to the booster battery and then
to a solid, stationary, unpainted, metallic
point (e.g. engine hanging hook) away
from the battery. Do not connect it to or
near any part that moves when the engine
is cranked.
When making the connections, do
not lean over the battery or acciden- tally let the jumper cables or clamps
touch anything except the correctbattery terminals or the ground. CAUTION
!
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm for several minutes with the accelerator ped-
al lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
clothsÐthey may now contain sulfuricacid. 8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked.

122If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
! 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 vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
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 vehicle. However, note that water draining from the air condi-
tioning 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 or the
coolant is leaking, stop the engine immedi-
ately. Call a Toyota dealer for assistance.
5. If the engine drive belt is O.K. and there
are no obvious leaks, you may help the en-
gine cool down more quickly 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 en- gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. CAUTION
!
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If necessary,
bring it up to half full again. Serious cool- ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer.

1. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traffic. Avoid stopping on the center divid-
er of a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emer-
gency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or re- verse (manual).
4. Have everyone get out of the vehicle
on the side away from traffic.
5. Read the following instructions thor-
oughly.
When jacking, be sure to observe
the following to reduce the possibil-
ity of personal injury: Follow jacking instructions.
Use a jack only for lifting your
vehicle during wheel changing.
Never get beneath the vehicle
when supported by a jack.
Do not start or run the engine
while your vehicle is supported by a jack. CAUTION

If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers
can still open the door for you, us-
ing their special tools. If you must break a
window to get in, we suggest breaking the
smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass.

142Where to go for service?
Toyota technicians are well-trained spe- cialists
and are kept up to date with the lat-
est service information through technical
bulletins, service tips, and in-dealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
What about do-it-yourself mainte- nance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Part 7. If you are a skilled do-it-yourself me-
chanic, the Toyota service manuals are recommended. Please be aware that do-
it-yourself maintenance can affect your
warranty coverage. See Owner's Guide,
Owner 's
Manual Supplement or W arranty
Booklet for the details. Listed
below are the general maintenance
items that should be performed as fre-quently as specified. In addition to check-
ing the items listed, if you notice any un-
usual noise, smell or vibration, you should
investigate the cause or take your vehicle
to your T oyota dealer or a qualified service
shop immediately. It is recommended
that any problem you notice be brought to
the attention of your dealer or the qualified service shop for their advice.
Make these checks only where
adequate ventilation can be ob-
tained if you run the engine. CAUTION
!
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.
