cooling CADILLAC XLR 2007 1.G User Guide

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant and
the proper coolant mixture.
{CAUTION:
You can be burned if you spill coolant on
hot engine parts. Coolant contains
ethylene glycol and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.

1. You can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pressure cap
and upper radiator hose, is no longer hot.
Turn the pressure cap slowly
counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the cap and remove it.3. Fill the coolant surge tank with the proper
mixture until the level inside the surge tank
stabilizes at the FULL COLD mark on the front
of the surge tank.
395

4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can
feel the upper radiator hose getting hot. Watch
out for the engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower,
add more of the proper mixture to the coolant
surge tank until the level stabilizes at the FULL
COLD mark on the coolant surge tank.
5. Then replace the pressure cap. Be sure the
cap is hand-tight and fully seated.If the LOW COOLANT message does not appear
on the Driver Information Center (DIC) after
two minutes, the coolant is at the proper ll level.
If a LOW COOLANT message does appear,
repeat Steps 1 through 3 then reinstall the
pressure cap, or see your dealer.

If you need to replace any of your wheels, wheel
bolts or wheel nuts, replace them only with
new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel
bolts, and wheel nuts for your vehicle.
{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle ground
clearance, and tire clearance to the body
and chassis.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause a crash. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if you need to, to get all the rust or
dirt off.
{CAUTION:
Never use oil or grease on studs or the
threads of the wheel nuts. If you do, the
wheel nuts might come loose and the
wheel could fall off, causing a crash.

Maintenance Footnotes
(a)A uid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the uid level checked. Add uid
if needed.
(b)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(c)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(d)Lubricate the trunk key lock cylinder. Lubricate
all body door hinges. Lubricate all hinges and
latches, including those for the hood, trunk,
console door, and any folding seat hardware. More
frequent lubrication may be required when
exposed to a corrosive environment. Applyingsilicone grease on weatherstrips with a clean cloth
will make them last longer, seal better, and not
stick or squeak.
(e)If you drive regularly under dusty conditions,
the lter may require replacement more often.
(f)Change automatic transmission uid and lter if
the vehicle is mainly driven under one or more
of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
(g)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 385 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
Contact your GM Goodwrench
®dealer if service is
required.
Underbody Flushing Service
At least every spring, use plain water to ush any
corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and
other debris can collect.
Recommended Fluids and
Lubricants
Fluids and lubricants identied below by name,
part number, or specication may be obtained from
your dealer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identied as
synthetic, and should also be
identied with the American
Petroleum Institute (API) Certied
for Gasoline Engines starburst
symbol. However, not all synthetic
API oils with the starburst symbol
will meet this GM standard. You
should look for and use only an oil
that meets GM Standard GM4718M.
