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).
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).

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.
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.
226 MAINTAINING YOUR VEHICLE
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 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.
