Hydraulic Brake System, Clutch Mechanism Fluid
Level
1. Brake fluid reservoir
Brake fluid level must be between the MIN and MAX
marks in the reservoir (1).
If the brake fluid is below the MIN mark, there may be
a fault in the hydraulic system. Have the system
checked as soon as possible by an authorized Sprinter
Dealer.Brake fluid
Refer to the "Recommended Fluids" chart later in this
section for recommended brake fluids.
In the course of its service life, the boiling point of the
brake fluid will fall due to the continuous absorption of
moisture from the atmosphere.
If the brakes are placed under heavy loads (e.g., on
steep hills) bubbles of steam can then form in the brake
system.
This will adversely affect the brakes' effectiveness.
Engine Cooling System
The use of aluminum components in Sprinter engines
requires that anticorrosive/antifreeze specifically
formulated to protect aluminum parts be used. The
factory approved Service Products are suitable for
Sprinter engines and can be mixed with the original
anticorrosion/antifreeze filled in at factory.
Cooling system design and anticorrosion/antifreeze
agent used stipulate the replacement interval for the
coolant solution in your vehicle. Please observe the
replacement interval specified in the Service Booklet
for your vehicle.
262 MAINTAINING YOUR VEHICLE
Failure to use MB 325.0 anticorrosion/antifreeze and/or
equivalent to DaimlerChrysler material standard MS-
9769 and/or adhere to the specified replacement interval
may result in a significantly shortened service life.
For coolant composition and water quality, contact
your authorized Sprinter Dealer.
Engine Coolant
The coolant is a mixture of water and a corrosion
inhibitor/antifreeze additive. Within the cooling
system, the corrosion inhibitor/antifreeze ensures
anti-corrosion protection
antifreeze protection
a higher boiling point.
The coolant added in the factory ensures adequate
antifreeze and anti-corrosion protection.
Refer to the "Recommended Fluids" chart for coolant
recommendations.
For reasons of anti-corrosion protection and to increase
the boiling point, the coolant added to the cooling
system is designed for all year round operation – even
in countries with high prevailing temperatures.Have the coolant renewed at least every 15 years or
after 160,000 miles.
When the coolant is renewed, the new coolant should
contain 50% antifreeze/corrosion inhibitor by volume.
This corresponds to antifreeze protection down to -
37 °C/-35°F.
Do not exceed a proportion of about 55 % by volume
(antifreeze protection down to about -45 °C/-49 °F) as
the heat dissipation properties then deteriorate.
In the event of coolant loss, do not add water only, but
sufficient antifreeze/corrosion inhibitor to maintain
the correct concentration.
The water in the coolant must satisfy certain
requirements. These are often met by tap supply
drinking water.
The water must be specially prepared if the water
quality does not come up to the required standards.
Have the corrosion inhibitor/antifreeze concentration
in the coolant checked at the outset of winter,
respectively once a year in countries with high
prevailing temperatures.

A regular check is included in the maintenance service.
Checking Coolant Level
Pressure cap on coolant reservoir (1)
The cooling system is pressurized. Only check the
coolant level with the vehicle parking on a level surface
and with the engine switched off.
– Wait until the coolant temperature has dropped
below 194 °F (+90 °C).
WARNING!
In order to avoid any possibly serious burns:
If you see flames or smoke coming from the
engine compartment, or if the coolant
temperature gauge indicates that the engine is
overheated, do not open the hood. Move away
from the vehicle and do not open the hood until
the engine has cooled. If necessary, call the fire
department.
Do not remove pressure cap on coolant reservoir
if engine temperature is above 194 °F (+90 ×C).
Allow engine to cool down before removing cap.
The coolant reservoir contains hot fluid and is
under pressure.
Using a rag, slowly open cap approximately 1/2
turn to relieve excess pressure. If opened
immediately, scalding hot fluid and steam will
be blown out under pressure.
264 MAINTAINING YOUR VEHICLE
Open the hood.
At first, only turn the pressure cap on coolant
reservoir to the first detent to release the pressure
from the cooling system. Only then should the
pressure cap be removed completely.
To add coolant:
If the engine is cold:
Add coolant until the coolant level reaches the base
area which is visible through the filler opening (area
moistened).If the engine is already at its regular operating
temperature:
Add coolant until the coolant level is about 0.6 inch
(1.5 cm) above the base area which is visible
through the filler opening.
Replace and tighten the pressure cap on coolant
reservoir.
If a large quantity of coolant has been lost, or if smaller
amounts are lost at regular intervals, have the engine
cooling system examined by an authorized Sprinter
Dealer.
For coolant composition and water quality, contact
your Sprinter Dealer.
WARNING!
Do not spill antifreeze on hot engine parts. Anti-
freeze contains ethylene glycol which may burn
if it comes into contact with hot engine parts.
Check coolant level only with the engine
switched off and the key in position 0 in the
ignition lock.

WINTER OPERATION
Have your vehicle winterized by an authorized
Sprinter Dealer before the onset of winter.
Have the engine oil changed, if the engine oil filled
is not approved for winter use.
Coolant: antifreeze/anti-corrosion concentration in
the coolant checked.
Windshield washer system and headlamp cleaning
system (optional): add windshield washer fluid
"winter wash" to the water, depending on ambient
temperatures.
Battery: the battery will lose capacity as
temperatures drop. Only a well-charged battery will
ensure reliable engine starting even at low outside
temperatures.
Tires: fit M+S radial tires with a minimum tread
depth of approximately 1/6 in (4 mm) on all wheels
for the winter season.BATTERIES
The standard battery is located in the engine
compartment.
WARNING!
Failure to follow these instructions can result in
severe personal injuries and death.
Never lean over batteries while connecting, you
might get injured, if the battery explodes.
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush
affected area with water and seek medical help if
necessary.
A battery will also produce hydrogen gas, which
is flammable and explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc.
Use only impact-resistant batteries with a central
gas release cover to prevent corrosion damage and
to prevent occupants from caustic burns in the
event of an accident.

Recommended Fluids and Lubricants
The manufacturer recommends for your vehicle model
the use of DaimlerChrysler approved fluids and
lubricants, e.g. engine oil, gear oil, automatic
transmission fluid, brake fluid, power steering fluid,
coolant and anti-corrosion/anti-freeze fluid only.
WARNING!
Failure to use fluids and lubricants which meet
the standards and specifications described in this
booklet or failure to adhere to the specified re-
placement intervals may result in damage to safe-
ty-related systems of your vehicle, such as the
brake system, which could cause an accident and/
or serious injury to you and others.
Use only fluids and lubricants meeting the
standards and specifications and adhere to
specified replacement intervals.
CAUTION!
Failure to use fluids and lubricants which meet
the standards and specifications described in this
booklet or failure to adhere to the specified
replacement intervals may result in a significantly
shortened service life and/or damage to
components of your vehicle, the repair of which
will not be covered by Warranty.
Use only fluids and lubricants meeting the
standards and specifications and adhere to
specified replacement intervals.
