2007 PONTIAC TORRENT engine overheat

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine will continue
cranking for a few seconds or until the vehicle
starts. If the engine does not start and the
key is held in START for many seconds,
cranking will be stopped after 15 seconds to
prevent cranking motor damage. To prevent
gear damage, this system also prevents
cranking if the engine is already running.
Engine cranking can be stopped by turning the
ignition switch to the ACC or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briey but then stops
again, do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.

Engine Coolant Heater
If your vehicle has this feature, in very cold
weather 0°F (−18°C) or colder, the engine coolant
heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the passenger’s
side of the engine compartment, near the
radiator.
3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and some
other things. Instead of trying to list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

Transaxle Overheating
If the transaxle uid temperature rises above
284°F (140°C) or rises rapidly, the Engine Coolant
Temperature Warning Light will ash. See
Engine Coolant Temperature Warning Light on
page 182for more information. When the transaxle
overheats it will go into a protection mode and
will default shift into fth gear if in the DRIVE (D)
position, or second gear if in the LOW (L)
position. Continue driving the vehicle in either
position depending on the required vehicle speed
and load. Once the uid temperature lowers to
the normal temperature range, the transaxle
will return to the normal shift patterns. Towing or
driving on long hills can cause the transaxle
uid temperature to be higher than normal. If the
transaxle uid temperature will not cool, you
may need to pull over and check the transaxle
uid level. You should also check the engine
coolant temperature. If it is hot, seeEngine
Overheating on page 360.
Parking Brake
The parking brake lever is located to the right of
the driver’s seat.
To set the parking brake, hold the brake pedal
down and pull up on the parking brake lever. If the
ignition is on, the brake system warning light will
come on.
To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can
press the release button. Hold the release button in
as you move the brake lever all the way down.
122

Make sure to release the parking brake before
driving the vehicle.
If the parking brake is applied and the vehicle is
moving at least 4 mph (6 km/h), a chime will
activate to remind you to release the parking brake.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify
that the parking brake is fully released and the
brake warning light is off before driving.
Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
CAUTION: (Continued)
CAUTION: (Continued)
Your vehicle can roll. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 328.
1. Hold the brake pedal down and set the
parking brake.
2. Move the shift lever into the PARK (P)
position by holding in the button on the
shift lever and pushing it all the way toward
the front of the vehicle.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you
can leave your vehicle with the ignition key in
your hand, your vehicle is in PARK (P).
123

Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle
could move suddenly if the shift lever is
not fully in PARK (P) with the parking
brake rmly set. And, if you leave the
vehicle with the engine running, it could
overheat and even catch re. You or
others could be injured. Do not leave your
vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever into
PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever
away from PARK (P) without rst pushing the
button. If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift
your transaxle into PARK (P) properly, the weight
of the vehicle may put too much force on the
parking pawl in the transaxle. You may nd
it difficult to pull the shift lever out of PARK (P).
This is called “torque lock.” To prevent torque lock,
set the parking brake and then shift into PARK (P)
properly before you leave the driver’s seat. To
nd out how, seeShifting Into Park (P) on
page 123.
When you are ready to drive, move the shift lever
out of PARK (P) before you release the parking
brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transaxle, so you can pull the shift lever
out of PARK (P).

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine has
overheated.
If this happens you should pull over and turn off
the engine as soon as possible. SeeEngine
Overheating on page 360for more information.
Notice:Driving with the engine coolant
temperature warning light on could cause your
vehicle to overheat. SeeEngine Overheating
on page 360. Your vehicle could be damaged,
and it might not be covered by your warranty.
Never drive with the engine coolant
temperature warning light on.
This light will also come on when starting your
vehicle. If it does not, have your vehicle serviced.
