Replacing headlight lamp (H4)
Loosen both rubber bands 1 and tilt headlight mask to the front. Remove
bulb plug
2 and remove rubber cap 3. Turn the supporting ring counter-
clockwise and remove it from the reflector together with the bulb.
Insert a new bulb such that the noses
4 fit into the recess 5. Do not touch
the glass body of the bulb, to keep if free from grease. Mount supporting
ring, rubber cap and plug. Position headlight mask with the bottom holders,
and fasten it with the rubber bands.
Cooling system
The water pump in the engine circulates the cooling liquid. However, the
cooling liquid can only circulate properly if the cooling circuit contains no air
bubbles.
Bleeding of the cooling system is therefore required
a) after adding more than 0.25 l cooling liquid and
b) after refilling the entire cooling system.
(see Bleeding the cooling system).
Some models are equipped with a thermostat
6 so that the engine reaches
its operating temperature more quickly. When the engine is cold, the liquid
coolant circulates in the cylinder and the cylinder head. As soon as the coo-
ling liquid has reached a temperature of approximately 55°C, the ther-
mostat opens and the cooling liquid is also pumped through the two alumi-
num radiators.
The cooling liquid is cooled by the air stream. This means that the cooling
effect decreases with the travelling speed. Dirty radiators additionally
reduce the cooling effect.

-
SCALDING HAZARD
!
–DO NOT DETACH ANY RADIATOR HOSES WHILE THE ENGINE IS HOT. THE ESCAPING
HOT COOLANT AND THE STEAM MAY CAUSE SERIOUS BURNS
.
–IN CASE YOU GET BURNT, HOLD THE AFFECTED PART OF YOUR BODY UNDER RUNNING
COLD WATER RIGHT AWAY
!
–C
OOLANT IS TOXIC. KEEP THE COOLANT OUT OF THE REACH OF CHILDREN!
–IN CASE COOLANT IS INGESTED, GO SEE A DOCTOR IMMEDIATELY!
–I
F COOLANT GETS INTO YOUR EYES, RINSE THEM OUT WITH WATER IMMEDIATELY
AND GO SEE A DOCTOR
!
A mixture of 40% anti freeze liquid and 60% water is used as coolant.
However, the anti-freeze protection must be at least -25° C (-13° F). This
mixture offers anti-freeze protection but also good corrosion protection and
should therefore not be replaced by pure water.
!
CAUTION
!
F
OR THE COOLING SYSTEM, USE ONLY WITH HIGH-GRADE ANTIFREEZE (I.E. SHELL
ADVANCE COOLANT). USING LOWER-GRADE ANTIFREEZE AGENTS, CAN CAUSE CORRO-
SION AND COOLANT FOAMING.
Pressure induced by heating of the coolant in the system is controlled by a
valve in the radiator cap
7; a water temperature of up to 120° C (248° F) is
admissible therefore, having to expect any trouble.
