engine PONTIAC FIREBIRD 1994 Service Manual

Your Driving and the Road
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, just move that hand to the left.
To move the trailer to the right, move
your hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making 7hms
When you’re turning with a trailer, make
wider turns than normal.
Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Thrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you signal a turn or lane change. Properly
hooked up, the trailer lights will also
flash, telling other drivers you’re about to
turn, change lanes or stop. When
towing a trailer, the green arrows
on your instrument panel will flash for
turns even
if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signal when
they are not. It’s important to check
occasionally to be sure the trailer bulbs
are still working.
Driving on Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer
work well.
On a long uphill grade, shift down and
reduce your speed to around
45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If you are towing a trailer and you
have an automatic transmission with
Overdrive, you may prefer to drive in
“D”
instead of Overdrive (or, as you need to, a
lower gear). Or,
if you have a manual
transmission with fifth (or sixth) gear and
you are towing a trailer, it’s better not to
use fifth (or sixth) gear. Just drive in
fourth gear (fifth gear if you have a six-speed manual transmission) or, as you
need to, a lower gear.
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill. If
-
something goes wrong, your rig could
start to move. People can be injured, and
both your vehicle and the trailer can be
damaged.
But if you ever have to park your rig on a
hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
“P” (Park) yet, or into gear
for a manual transmission.
2. Have someone place chxks under the

4. Reapply the regular brakes. Then

for a manual transmission.
5. Release the regular brakes.

Maintenance When Trailer Towing
Your vehicle will need service more often
when you're pulling a trailer. See the
Maintenance Schedule for more on this.
Things that are especially important in
trailer operation are automatic
transmission fluid (don't overfill), engine
oil, axle lubricant, belts, cooling system,
and brake adjustment. Each of these
is
covered in this manual, and the Index will
help you find them quickly. If you're
trailering, it's a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch
nuts and bolts .are tight.

Find the positive (+) and negative (-)
terminals on each battery. 5. Check that the jumper cables don’t
have loose
or missing insulation. If
they do, you could get a shock. The
vehicles could be damaged, too.
Before
you connect the cables, here
are some basic things
you should
know. Positive
(+) will go to positive
(+) and negative (-) will go to
negative
(-) or a metal engine part.
Don’t connect
(+) to (-) or you’ll get a
short that would damage the battery
and maybe other parts, too.

6. Connect the red positive (+) cable to
the positive
(+) terminal of the vehicle
with the dead battery. Use a remote
positive
(+) terminal if the vehicle
has one.
I‘ 7. Don’t let the other end touch metal.
Connect it to the positive
(+) terminal
of the good battery. Use a remote
positive
(+) terminal if the vehicle
has one. But don’t use the junction
block on your Pontiac.
8. Now connect the black negative (-)
cable to the good battery’s negative
(-) terminal.
Don’t let the other end touch anything
until the next step. The other end
of
the negative cable doesn’t go tathe
dead battery. It goes to a heavy
’
unpainted metal part on the engine
of the vehicle with the dead battery.

IO.
Attach the cable at least 18 inches
(45 cm) away from the dead battery,
but not near engine parts that move.
The electrical connection is just as
good there, but the chance of sparks
getting back to the battery is much
less.
Now start the vehicle with the good
battery and run the engine for a
while.
11.
12.
Try to start the vehicle with the dead
battery.
If it won't start after a few tries, it
probably needs service.
Remove the cables in reverse order
to prevent electrical shorting. Take
care that they don't touch each other
or any other metal.

Towing a vehicle over rough surfaces
could damage a vehicle. Damage
can occur from vehicle-to-ground
or vehicle-to-wheel-lift-equipment
contact.
To help avoid damage, install
a towing dolly and raise vehicle until
adequate clearance is obtained between

Engine Overheating
I
If Steam Is Coming from Your Engine:
You will find a coolant temperature gage
on your Pontiac’s instrument panel.
You may also find a low coolant warning
light
on your Pontiac instrument panel.

ProCarManuals.com

Problems on the Road
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly darhaged.
The costly repairs would not be
covered by your warranty.
If No Steam Is Coming from Your
Engine:
If you get the overheat warning but see
or hear
no steam, the problem may not be
too serious. Sometimes the engine can gel
a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer. If you
get the overheat warning with
no
sign of steam, try this for a minute or so:
1. If you have an air conditioner, turn it
2. Turn on your heater to full hot at the
off.
highest
fan speed and
open the
window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine runs
slower).
If you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for about
ten minutes. If the
warning doesn’t come back
on, you can
drive normally.
If the warning continues, pull over, stop,
and park your vehicle right away.
If there’s still no sign of steam,
you can
idle the engine for two or three minutes
while you’re parked, to see if the warning
stops. But then, if you still have the
warning, TURN
OFF THE ENGINE
AND GET EVERYONE OUT
OF THE
VEHICLE until it cools down.
You may decide not to lift the hood but to
get service help right away.
Cooling System
When you decide it’s safe to lift the hood,
here’s what you’ll see on the V6 engine:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fan
. . .I62
ProCarManuals.com

On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
If the coolant inside the coolant recovery
tank is boiling, don’t do anything else
until it cools down.
When it
is cool, remove the coolant
recovery tank cap and look at the dipstick.
The coolant level should be at
or above
“FULL
COLD.” If it isn’t, you may have
a leak in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
If there seems to be no leak, check to see
if the electric engine fan is running. If the
engine
is overheating, the fan should be
running.
If it isn’t, your vehicle needs
service.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t at or above the
“FULL COLD’ mark, add a 50/50
mixture of clean water (preferably
distilled) and a proper antifreeze at the
coolant recovery tank. (See “Engine
Coolant” in the Index for more
information about the proper coolant
mix.)
NOTICE:
I
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other parts. Use the
recommended coolant. When the coolant
in the coolant recovery
tank is at or above the “FULL COLD’
mark, start your vehicle.
If the overheat warning continues, there’s
one more thing
you can try. You can add
the proper coolant mix directly to the
radiator, but be sure the cooling system is
cool before
you do it.
