The Brussels Post, 1978-04-05, Page 22When checking radiator hoses, be certain the engine is cool. Should a hose be so dete-
riorated that it breaks, you're apt to get an unwanted bath of scalding radiator coolant.
Checking hoses is just one step to take when making sure system is okay, says the Auto-
motive Cooling System Institute.

26 CAR CARE SECTION.
Keep cooling system in working order
Maintenance of three
areas most important
Some cars or components,
when they fail, cause the
engine to stop at once. The
ignition system is a good
example. Others, like the
braking system, create haz-
ardous situations. And elec-
trical trouble, at best, is in-
convenient when the car
won't start.
Failure in other areas,
such as the engine lubrica-
tion or cooling systems, can
be destructive. These are the
main safeguards of the en-
gine. Without oil or coolant
the engine can seize up, with
possibly major damage as a
result.
The latter system is rela-
tively easy to understand
and check, says the Auto-
motive Cooling System In-
stitute. In addition to the
anti-freeze/coolant, you'll be
concerned with the condi-
tion of belts, hoses and
clamps, thermostat, pressure
cap and radiator.
Main components
These are the main com-
ponents involved in a cool-
ing system tune-up. They
should be checked as follows :
1. BELTS. They drive the
fan and water pump as well
as other engine accessories.
Look for frayed, glazed or
cracked belt surfaces that
. might cause the belt to slip
or break. If you find one
belt worn, look closely at
the others. They're prob-
ably ready for replacement
too.
If the belts look okay,
check the tension. A belt
should deflect no more than
a half-inch to an inch when
depressed half way between
the pulleys.
2. HOSES. Squeeze item
hard to be sure they are not
getting brittle, mushy or
otherwise deteriorated. Do
this when the engine is cold;
your test might cause a bad
hose to let go, with resultant
hot anti-freeze all over you.
A hose of dubious condi-
tion should be scrapped, and,
as with belts, the failure of
one hose may indicate the
imminent failure of others.
Replace any that look mar-
ginal, to prevent the possi-
bility of expensive and in-
convenient failure.
Most mechanics replace
the clamps when installing
new hose. It's a wise invest-
ment whether you are a do-
it-yourselfer or have it done.
3'. THERMOSTAT. A
sticking thermostat will
cause too hot or too cold
engine operations. You will
recognize this by the obvious
signs of engine overheating
or by little or no heat from
the heater. In either case, a
new thermostat is needed.
When in doubt, have your
mechanic check it for you.
Finally, when you are sure
everything is tight and leak
proof, you come to the final
step in your cooling system
tune-up: flushing the system
and installing new anti-
freeze/coolant. If it has been
a year or more since you
last changed it,. drain 'the
old, flush the system with a
good chemical cleaner and
