2007 DODGE SPRINTER cooling

6 IntroductionOperating safetyDo not allow the electronically stored total
distance covered by your vehicle to be
modified as a result of tampering with the
electronics system.
This type of modification or failing to in-
form the buyer when selling the vehicle
could constitute an offense punishable by
law, depending on the country concerned.
Having the engine power output of your
vehicle increased by tampering with the
electronic engine management system will
invalidate the vehicle’s general operating
permit and insurance coverage, as well as
your warranty and warranty entitlement.
Modifications to the output of the engine
must be reported to the insurance provider
and require the vehicle to be recertified.
The tires, chassis, brake and cooling sys-
tems must be adapted to the increased en-
gine power output.Tampering with the electronic engine man-
agement system modifies emission values
and it will not be possible to guarantee the
operating safety of the engine in every
case. Increases in performance may lead
to malfunctions and consequential dam-
age to other assemblies.
If you sell the vehicle, failing to inform the
buyer of the modified engine power output
could constitute an offense punishable by
law, depending on the country concerned.
The manufacturer recommends the use of
genuine Sprinter parts and conversion
parts as well as accessories that have
been expressly approved for your vehicle
model (\2page 352).
These parts have been subjected to spe-
cial tests in order to determine their safety,
reliability and suitability.Body builder guideline
If you intend on making any alterations to
the vehicle, we strongly recommend that
you select one of the following options in
order to obtain all necessary information:
\4Contact the authorized Sprinter Dealer
nearest you to obtain a copy of the
Sprinter Body Builder Guideline.
\4Call DaimlerChrysler Vans LLC at tele-
phone (800) 992-1997 to request a
copy of the Sprinter Body Builder
Guideline (there may be a charge).

Tempmatic is only operational while the
engine is running. You can use Tempmatic
to regulate or control the temperature au-
tomatically. The vehicle is either heated or
cooled, depending on the temperature se-
lected and the outside temperature.
The combination filter removes most dust
particles, pollen and unpleasant odors
from the outside air.
The interval for replacing the filter depends
on environmental factors, e.g. high air pol-
lution. The interval may be shorter than
that indicated in the Service Booklet.

Warning
G
Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise fog up. As a result,
you could be distracted from road and traffic
conditions and cause an accident.Warning
G
Air flowing out of the air vents in the footwell
when Tempmatic is in operation may be very
hot or very cold. There is therefore a risk of
frostbite or burns to bare skin in the imme-
diate proximity of these outlets. Keep bare
skin away from these air outlets. If neces-
sary, direct the airflow into a different area
of the vehicle interior using the air distribu-
tion control.

The air in the vehicle is neither cooled nor
dehumidified when economy mode is se-
lected.
\1To activate: press the° switch for
economy mode.
The indicator lamp in the switch comes
on.
\1To deactivate: press the° switch
for normal mode.
The indicator lamp in the switch goes

iIf the vehicle interior has been heated
up, ventilate the vehicle before starting
your journey or briefly switch to air-re-
circulation mode for faster cooling.
Keep the air inlet on the hood free from
ice and snow.
Position the sliders for the center air
vents in the central position to provide
practically draft-free ventilation.

The expansion tank is in the engine com-
partment. Only add coolant with the vehi-
cle standing on a level surface and with the
engine switched off. The coolant tempera-
ture must have dropped below 122 °F
(50 °C).1Coolant tank cap

\1Slowly unscrew cap1 counterclock-
wise to reduce excess pressure.
\1Continue turning the cap and remove
it.
\1Add coolant as far as the MAX mark.
\1Twist cap1 back on.
For coolant specifications, see "Service
products and capacities" (\2page 355).Environmental note
H
When adding oil, take care not to spill any.
No engine oil must be allowed to enter sew-
age systems, surface water, ground water or
soil.
You would otherwise be damaging the envi-
ronment.
Dispose of engine oil in an environmentally
responsible manner. Comply with the manu-
facturer’s instructions.Coolant
Warning
G
When opening the coolant expansion tank
there is a risk of scalding from hot coolant
spraying out. The cooling system and the
coolant expansion tank are pressurized
when the engine is at normal operating tem-
perature.
Wear gloves and eye protection. Only open
the coolant expansion tank when the cool-
ant temperature is less than 122 °F (50 °C).
N20.30-2063-31
Warning
G
Coolant contains glycol and is therefore tox-
ic. Do not swallow coolant. Consult a doctor
immediately if any coolant is swallowed.
Do not allow coolant to come into contact
with your skin, eyes or clothing. In the event
of contact with the eyes, rinse them thor-
oughly with clean water. Clean skin and
clothes immediately with soap and water.
Change out of soiled clothing without delay.

192 OperationEngine

The reservoir is in the engine compart-
ment. Check the brake fluid level:
\4regularly, e.g. weekly or when refueling
\4only with the vehicle standing on a level
surface and with the engine switched
off1Coolant tank cap
2Brake fluid reservoir cap
3Windshield washer reservoir cap
The brake fluid level must be between the
MIN and MAX marks.
!
CAUTION
Check the cooling and heating systems
regularly for leaks. If a large quantity of
coolant is lost, have the cause traced
and rectified at an authorized Sprinter
Dealer.
Brake fluid
iThere is usually a notice in the engine
compartment to remind you when the
next brake fluid change is due.
N20.30-2063-31
!
CAUTION
Brake fluid corrodes paintwork. If
brake fluid comes into contact with the
paintwork, immediately rinse with wa-
ter.
If the brake fluid does not reach the
MIN mark, the vehicle’s hydraulic sys-
tem could be malfunctioning. Do not
add brake fluid under any circumstanc-
es. This will not solve the problem.
Do not drive any further.
Have the system checked immediately
at an authorized Sprinter Dealer.
Warning
G
Brake fluid is hazardous to health. Do not
swallow brake fluid. Consult a doctor imme-
diately if any brake fluid is swallowed.
Brake fluid must not come into contact with
the skin, eyes or clothing. Wash affected ar-
eas with plenty of clean water and consult a
doctor immediately if necessary.
