214 MAINTAINING YOUR VEHICLE
Open the hood.
At first, only turn the radiator cap to the first detent
to release the pressure from the cooling system.
Only then should the radiator 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
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.
Do not spill antifreeze on hot engine parts.
Antifreeze 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.

7
(1.5 cm) above the base area which is visible
through the filler opening.
Replace and tighten the radiator cap.
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.
WINTER OPERATIONHave 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: add winter concentrate
to the washer fluid.
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, taking note of the
maximum permissible speed of the tires fitted.
