cooling system, the anti-freezing solution expands approxi -
mat ely 2 pints on h eating from 30 ° to 160° F ., and a corre -
sponding space should be left wh en adding liquid to the radi-
ator.
A
hydrometer test will !Jl.dicate whether anti-freeze, or
water, or both sh ou ld be added to bring the solution to the
proper l e~el and to maintain the de sired freezing }Xlint.
Testing. Some devices, used for testing anti-freezing so luti ons,
will indicate
the correct freezing point only wh en the t est is
made at a specific t empera -
tur e. Other test ers, prov ided
with thermometers an d
ta
bl es, in dicate the freezing
points corresponding
to re ad-
ings ma de at various tem-
peratures (fig. 42). Disre-
garding the te mp er ature of
th e so lution, wh en t~sted,
may cause an error as lar ge
as 30 ° F.
Some testing devices are
made to test only one kind of
anti -freezing solution. Others
h ave sev eral scales and may
be u se d for the correspond-
ing
kinds of anti-freeze.
The freezing point of a
soluti on containing both al -
co hol and eth ylene gl yco l
cannot be determined accu-
rately by means of a hydrometer.
CLUTCH
Description. Th e clutch, which provides a means of disconnect-
ing
