water + additive agent from the cooling system and add the following mixture:
50% of water + 50% of additive agent Havoline XLC.
ATTENTION:
Do not remove the cooling system cap when the engine temperature is over 90º
C; the system steam may cause severe burn injuries.
If it is absolutely necessary remove the cooling system cap when the engine is hot
(over 50º C), cover the cap with a thick cloth and turn slowly until the first slot and
let the steam go out. Then turn the cap until the second slot and remove it.
THERMOSTATIC VALVE
It is situated on the upper front part of the engine block, controls the cooling
system water flow.
When the engine is cold, the thermostatic valve restricts the water passing to
the radiator, circulating only in the engine. When the water temperature arrives at
the value specified for the engine operation regime, the thermostatic valve starts
opening, permitting the water circulation in the system.
HYDRAULIC CLUTH SYSTEM
CLUTCH COUPLING
Clutch Pedal
The clutch coupling features hydraulic auto-adjuschart command, therefore, it is
not needed to be adjusted.
In case of superheating, do not disactivate the engine immediately: let it operating
idle until the temperature drops up to the normal levels. After it, switch off the
engine and check the cause(s) of the superheating.
Cooling Liquid Change and Cleaning of the System.
For better cleanout of impurities, carry out the liquid drainage a few minutes after
the engine stopped operating, but wait until the water is cooled.
Cooling liquid change procedure:
a) Remove the cap of the compensation tank(1); (Previos figure)
b) Release the clamp ring (2) and
disconnect the lower hose of the
radiator;
c) After the drainage and cleaning
of the system, fill it with clean
water with additive agent according
to the following note:
NOTE:
1- If the cooling system water is not added with an additive agent, it will cause
erroneous conditions for a good operation of the engine;
See also item Cooling System, in the Specifications.
When the temperature is close or equal to zero, it is necessary to remove the
