1986 CHEVROLET CORVAIR fuel pump

Downloaded from www.Manualslib.com manuals search engine Also, all hoses, fittings and the inlet air filter should be
inspected, cleaned and replciced if necessary.
NOTE: If the positive crankcase ventilator valve should
become
dogged, the engine idle will be adversely
affect~d. Therefore, if the engine idle becomes too slow
or rough, the ventilator valve should be checked before
any carburetor ad;ustments are made to compensate for
the trouble.
AIR INJECTION REACTOR (A.I.R.l
The Air
Injection Reactor system is designed to re­
duce .air pollution caused by exhaust emissions. It is entirely separate from the Positive Crankcase Ventilating
system. The Air
Injection Reactor system operates by
oxidizing (or burning) the
hydrocarbons and carbon
monoxide as they are expelled from the combustion
chamber into the exhaust. A positive displacement air
pump, driven by the engine, compresses clean frltered
air, which
is distributed and injected at the exhaust part
of each cylinder. This fresh air mixes with the hot exhaust
gases and promotes further oxidation (or burning) of
both hydrocarbons and carbon monoxide by converting
some
of them to carbon dioxide and water. This does not
reduce the danger of inhaling carbon monoxide in con­
frned areas. See page 7 for carbon monoxide warning.
Supplementing
the air pump a special carburetor and
distributor plus related components are required.
The Air
Injection Reactor system should have the A.I.R. pump filter serviced and the drive belt inspected
for
wear and tension every 12 months or 12,000 miles,
38
whichever occurs frrst. In addition, complete effectiveness
of the system, as well as full power and performance,
depends upon idle speed, ignition timing, and idle fuel
mixture being
set according to specifrcation. A quality
tune-up which includes
these adjustments should be per­
formed periodically to assure normal engine efficiency,
operation and performance.
STEERING GEAR
Every 36,000 miles -Re­
move frller plug and
check lubricant level. If
necessary, add water
resistant EP chassis lu­
bricant which meets
General Motors Specifr­
cation GM 6031 M to
bring to level
of frller
plug hole.
FAN BELT
Every 6000 miles-check condition of belt. Check belt
guide to belt clearance. Belt guide ciearance should
be approximately 1/16" after belt is tensioned.
(See page 49). Retensioning a belt unnecessarily
may result
in premature belt fciilure.
ENGINE OIL CHANGE INTERVAL
Change engine oil each 4 months. If more than
6000 miles are driven in a 4-month period, change oil

The chart on the previous page, and the information on the pages
which follow, contains information designed to aid the average
driver to discover, and possibly correct, conditions resulting in minor
mechanical
difficulties in his car. The chart, designed to point out
possible solutions to
several of the most common automotive mal­
functions
and point out a logical checking sequence, will lead step
by step to the most likely causes and corrective procedures. If, after
making the checks and adjustments suggested, the source of the
trouble
has not been found and corrected, it is strongly recom­
mended
that an Authorized Chevrolet Dealer inspect the vehicle and
make whatever repairs or adjustments are necessary.
FUEL SYSTEM AND ENGINE
If the ignition switch will cause the engine to "turn over" or
"crank" but the car will not start, check Steps A through D below.
NOTE:
If continual "flooding" of the carburetor is evidenced by a
carburetor wet with fuel or black exhaust smoke, perform the
operation
suggested in paragraph 0 only .
(A) The first and most obvious,
and one of the most frequently
overlooked, items to check when
you
have- difficulty in starting your
car is the amount of fuel in the
tank.
Make it a habit to check the
FUEL GAUGE regularly and most
especially
at a time when the en­
gine will "turn over" but will not
start.
(8)
If the fuel tank is not empty, Checking Fuel Flow
47
you may check further to see whether the fuel is reaching the
engine. Disconnect the fuel lines
at the carburetor. Place a jar or cup
under open line and briefly "crank" the engine by means of the
starter. If fuel spurts from the line, you may assume that the FUEL
LINES are clear and the FUEL PUMP is operating properly. If no fuel
leaves the line, either the fuel lines
or fuel pump are at fault. See
your Authorized Chevrolet Dealer.
(C) Before reconnecting the fuel lines to the carburetor, remove
the
FUel FilTER from carburetor inlet and check its condition.
If it appears to be clean, replace it and reconnect the fuel lines. If
the filter appears to be plugged, clean it as well as possible by
scraping out the foreign material and cleaning in a solvent. Then
reinstall the filter
and repeat the procedure with the second carbu­
retor. Replace the filters with new ones as soon as possible .
(0) If the fuel seems to be reaching the carburetors properly, the
problem may
be: an EMPTY CARBURETOR BOWL caused by a
"stuck shut" float valve or a flOODED CARBURETOR caused by a
"stuck open" condition and evidenced by gasoline flowing down
the outside
of the carburetor; or a stuck CHOKE valve. Remove the
air cleaners from the carburetors. Check that the choke valves move
freely and are not stuck. Tap the side of the carburetors sharply
several times with a light tool such as a screwdriver handle or pliers.
Replace the
air deaners and attempt to start the engine in the
normal manner.
(E) If the car will start but stalls when hot or has a rough idle,
you
can suspect a faulty IDLE ADJUSTMENT, or extremely dirty
