COOLING SYSTEM
Coolant Circuit
Every 500 miles or weekly - Check
the coolant level in system expansion
tank, with cold engine: the level must
3lways be abt. 7 cm (2y.
F
in) above the
M!N mark on tank.
When engine is very hot the level
might rise noticeably: this could afso
happen immediately after stopping the
engine.
Should the coolant level drop below
the tank MIN mark, top up by removing
expansion tank cap and pouring in
coolant, seeing that its level is as
specified.
Warning: Do not remove radiator or
expansion tank caps on a hot engine
to avoid possibly scorching your hands;
wait until engine has cooled down.
Do not top up a hot engine with
cold water.
Should more than 2 conse-
cutive top-ups be required at
short intervals, or after limited
mileages (500 miles), the system needs
checking, This applies also when
water temperature gage pointer stays
on the red sector (see page 6).
To drain cooling system, move
lever D to the left {see page 12),
open the cocks on radiator lower side
and on cylinder block, and disconnect
expansion tank hose.
To fill the system:
— Connect expansion tank hose, close
radiator cock and remove plug A.
— Pour in water siowly through radia-
tor filler port until water overflows,
then refill the expansion tank.
— Refit radiator and expansion tank
caps and plug A then run the
engfne so as to favor a thorough
mixing of the fluid in the system.
— Stop the engine, slacken plug A,
wait for a proper system bleeding
and refit the plug.
— With engine cold check the level
in expansion tank and, if nee. top up.
Antifreeze Mixture
The cooling system is filled with an
antifreeze mixture effective down to
— 35 "C (—32
(1
F). In case of coolant
change or topping-up FIAT recom-
mends the use of a 50-50 mixture of
water and Paraflu 11 fluid {or equi-
valent), which allows the use of hard
or chlorinated water and incorporates
