Ribbed V-BeltThe ribbed V-belt drives the accessories, such as
generator, coolant pump and hydraulic steering pump.
The ribbed V-belt is automatically kept tensioned.
Check the state of the ribbed V-belt regularly, such as
at every engine oil level check.
The belt must not be damaged, worn, oiled or glazed.
There must be no cracks in the belt running surface.
Replace damaged belts.
Hydraulic Brake System, Clutch Mechanism Fluid
Level1. 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.

212 MAINTAINING YOUR VEHICLEBrake fluidUse brake fluid approved to MB 331.0, or a DOT 4
brake fluid with: minimum dry boiling point (ERBP)
500
°F, minimum wet boiling point (WERBP)
356°F, maximum viscosity 1500 mm
2/s,
conforming to FMVSS116 and ISO 4925.
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 CoolantThe 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.
Use coolant approved to MB 325.0, such as Valvoline
GO5, or an equivalent Extended Life Coolant.
To avoid damage to the cooling system, only use
manufacturer approved corrosion inhibitor/
antifreeze additives.
Information on the corrosion inhibitor/antifreeze
additive is available from any Sprinter Dealer.
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.

A ppearance Car and Corrosion ProtectionIn operation, your vehicle is subjected to varying
external influences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and
varying climatic conditions, but also by air pollution,
road salt, tar, gravel and stone chipping. Grease and
oil, fuel, coolant, brake fluid, bird droppings, insects,
tree resins etc. should be removed immediately to
avoid paint damage. Frequent washing reduces and/or eliminates the aggressiveness and potency of the
above adverse influences.
More frequent washings are necessary to deal with
unfavorable conditions; for example operation near the
ocean, in industrial areas (smoke, exhaust emissions),
or during the winter months.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should
be repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection.
Damaged areas need to be undercoated again.
Your vehicle has been treated at the factory with a wax-
base rustproofing in the body cavities which will last
for the lifetime of the vehicle. Post-production
treatment is neither necessary nor recommended by
DaimlerChrysler Corporation.
Because of the possibility of incompatibility between
materials used in the production process and others
applied later.
WARNING!
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always fol-
low the instructions on the particular container.
Always open your vehicle’s doors or windows
when cleaning the inside.
Never use fluids or solvents that are not designed
for cleaning your vehicle. Do not use fuel as a
cleaning agent. Fuel is flammable and constitutes
a health hazard.

220 MAINTAINING YOUR VEHICLEScratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be
removed or repaired with car-care products. In such
cases it is best to seek aid by your authorized Sprinter
Dealer.
The following topics deal with the cleaning and care of
your vehicle and give important "how-to" information
as well as references to car-care products.
Power WasherWhen using a power washer for cleaning the vehicle
always observe manufacturers’ operating instructions.
WARNING!
Never use openings in the bodywork as steps.
You could otherwise damage the vehicle and it
could lead to an accident.
CAUTION!
Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder, which will
scratch metal and painted surfaces.
CAUTION!
The intense jet of water of a round nozzle can
result in damage to the tire. Therefore never use a
round nozzle to power wash tires.
Always replace a damaged tire.
Always keep the jet of water moving across the
surface. To avoid damaging the vehicle, do not
aim the water jet directly at electrical components,
end of electrical lines, electrical connectors, intake
or ventilation openings, brake hoses, door joints,
seals, other rubber parts.
