pressure reduces fuel economy and
may result in abnormal tire wear
and adverse vehicle handling. Too

Tire inflation pressures should
be checked at least monthly when
the tires are "cold" and when
changing the load you plan to carry
in your vehicle.

applies to the tire pressure when
a vehicle has not been driven for

It is normal for tire pressures to
increase 4-8
PSI when the tires
become hot from driving. Do not
"bleed" (reduce tire inflation
pressures) after driving your
vehicle. Bleeding serves to in­
crease tire flexing and heat build­
up which can result in tire dam­
age and failure.
3. For sustained driving at turn­
pike speeds, cold inflation
pressures should be increased 4
PSI above the recommended
cold inflation pressures on the
tire placard up to a maximum of
32
PSI for load range Btires, 36
PSI for load range C, and 40 PSI
for load range D. Sustained
speeds above 75 mph are not
recommended when the 4
PSI
adjustment would require pres­
sures greater than the maximum
pressures above.
4. Always use a tire pressure gauge
(a pocket type gauge is recom­
mended) when checking
infla~
tion pressures. Underinflated
radial tires may have the same
appearance
as a properly inflated
radial tire.
Visual inspection of
tires for inflaton is totally inade­
quate especially in the case
of
radial tires. If inflation pressure
of an individual tire
is found to be
consistently low, have your
dealer find and correct the cause.
5. Be sure to re-install the tire in­
flation valve caps, if
so equipped,
to prevent dirt and moisture
from entering the valve core
which could cause air leakage.
Inspection and Rotation
Your tires perform different jobs
(front tires are involved with steer­
ing and rear tires normally with
propelling the vehicle) and can
wear differently depending on the
type of roads driven, individual

Downloaded from www.Manualslib.com manuals search engine Air Cleaner
Your car receives its power from
a mixture of gasoline and air. The
air
is taken in to the system through
the air cleaner
so it's important to
replace the air cleaner at required
intervals. A dirty air cleaner re­
duces engine efficiency.
Properly Tuned Engine
Overall tuning (a check on tim­
ing, spark plugs, emission control
devices, etc.) can improve your
car's gas mileage. You just can't
expect an
"out-of-tune" engine to
give you good gas mileage and
cleaner air.
Excess Weight
Fuel economy is related to the
work the engine must do. The
heavier the load, the more power it
takes. Keep excess weight to a
minimum by removing any per­
sonal effects or luggage from the
car or trunk when they are not
needed.
Tire Inflation
Underinfiation not only causes
needless wear of the tires, but can
also waste gasoline. It's a good
idea to check tire pressures
regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" can
have the effect
of dragging your
front tires sideways and may cause
premature tire wear.
It takes power
to carry this extra load and that
takes gas from your tank.
Catalytic Converter
The catalytic converter IS an
emission control device added to
5-22
the exhaust system to reduce hy­
drocarbon and carbon monoxide
pollutants from the exhaust gas
stream.
The converter contains
beads which are coated with a cata­
lytic material containing platinum
and palladium.
Use of the catalytic converter
has the advantage of allowing the
engine to be re-tuned for improved
fuel economy and driveability.
The catalytic converter requires
the use
of unleaded fuel only.
Unleaded gasoline is used to re­
duce combustion chamber deposits,
corrosion and
to prevent lead con­
tamination of the catalyst that
would render it ineffective.
The use
of leaded fuel will cause the cata­
lytic converter to
become ineffec­
tive as an emission control device.

The headlamp circuits are protected by a circuit breaker in the
light switch . An -electrical overload will cause the lamps to go on
and off. or in some cases to remain off. If this condition develops,
have your wiring circuits checked immediately.

An Air Conditioning high blower fuse, 30 amp. is located in an In-line fuse holder running from horn relay to Air Conditioning relay.
Do not use fuses of higher amperage rating than those recommended above.
Fusible Links are incorporated into the wiring system, These are wires of such a gauge that they will fuse (or melt) before damage occurs to an entire wiring harness in the event of an electrical overload. See your Chevrolet Dealer if fusible link replacement becomes necessary.
