GENERAL DESCRIPTION

A pressure cooling system is provided for on all

models by a pressure type radiator cap (fig. 1). The

pressure type radiator cap used is designed to hold a

pressure above atmospheric pressure in the cooling

system. Excessive pressure is relieved by a valve within

the cap that opens to radiator overflow.

The water pump is a ball bearing, centrifugal vane

impeller type. It requires no care other than to make

certain the air vent at the top of the housing and the drain

holes in the bottom do not become plugged with dirt or

grease. Removal and installation of the water pump is

covered in this section. For overhaul procedures of the

water pump refer to Section 6K of the Passenger Chassis

Overhaul Manual.
For radiator, refer to Section 13 of this manual For

radiator shroud, refer to Section 11 of this manual.

MAINTENANCE AND ADJUSTMENTS

Coolant Level

The radiator coolant level should only be checked when

the engine is cool, particularly on cars equipped with air

conditioning. If the radiator cap is removed from a hot

cooling system, serious personal injury may result

The cooling system fluid level should be maintained

one inch below the bottom of the filler neck of the radia-

tor when cooling system is cold, or at the bottom of the

filler neck when the system is warm. It is very impor-

tant that the correct fluid level be maintained. The seal-

ing ability of the radiator cap is affected when the cooling

level is too high.

All passenger car cooling systems are pressurized

with a pressure cap which permits safe engine operation

at cooling temperatures of
up
to 247°F.

When the radiator cap is removed or loosened, the

system pressure drops to atmospheric, and the heat

which had caused water temperature to be higher than

212°F, will be dissipated by conversion of water to

steam. Inasmuch as the steam may form in the engine

water passages, it will blow coolant out of the radiator

upper hose and top tank, necessitating coolant replace-

ment Engine operating temperatures higher than the

normal boiling point of water are in no way objectionable

so long as the coolant level is satisfactory when the

engine is cooL

Upon repeated coolant loss, the pressure radiator cap

and seat should be checked for sealing ability. Also, the
cooling system should be checked for loose hose con-

nections, defective hoses, gasket leaks, etc.

Coolant System Checks

1.
Test for restriction in the radiator, by warming the

engine up and then turning the engine off and feeling

the radiator. The radiator should be hot at the top

and warm at the bottom, with an even temperature

rise from bottom to top. Cold spots in the radiator

indicate clogged sections.

2.
Water pump operation may be checked by running the

engine while squeezing the upper radiator hose. A

pressure surge should be felt Check for a plugged

vent-hole in pump.

NOTE:
A defective head gasket may allow ex-

haust gases to leak into the cooling system.

This is particularly damaging to the cooling

system as the gases combine with the water to

form acids which are particularly harmful to

the radiator and engine.

3.
To check for exhaust leaks into the cooling system,

drain the system until the water level stands just

above the top of the cylinder head, then disconnect

the upper radiator hose and remove the thermostat

and fan belt. Start the engine and quickly accelerate

several times. At the same time note any appreci-

able water rise or the appearance of bubbles which

GENERAL DESCRIPTION

Various carburetors (fig. lc) are used with Chevrolet,

Chevelle, Chevy II, Camaro and Corvette passenger

vehicles. These carburetors are designed to meet the

particular requirements of engines, transmissions and

vehicles, therefore carburetors that look alike are not

always interchangeable. (Refer to carburetor part num-

ber and/or specifications.)

Because many service procedures for the various

carburetors are similar, typical illustrations and pro-

cedures are used except where specific illustrations or
procedures are necessary to clarify the operation.

This section covers removal, installation and adjust-

ments (on engine) of carburetors. Also covered in this

section are maintenance procedures for choke coils,

throttle linkage and fuel filters. For carburetor .over-

haul procedures and additional adjustments (bench), re-

fer to Section 6M of the Overhaul Manual under the

carburetor being serviced.

Specifications for carburetors are located in the back

of this manual.

SERVICE PROCEDURES

Preliminary Checks

1.
Thoroughly warm-up engine. If the engine is cold,

allow to run for at least 15 minutes.

2.
Inspect torque of carburetor to intake manifold bolts

and intake manifold to cylinder head bolts to exclude

the possibility of air leaks.

3.
Inspect manifold heat control valve (if used) for free-

dom of action and correct spring tension.

Idle Speed and Mixture Adjustment (Except Air Injection

Reactor System)

NOTE:
This adjustment should be performed

with engine at operating temperature and park-

ing brake applied.

1.
Remove Air Cleaner.

2.
Connect tachometer and vacuum gauge to engine, then

set hand brake and shift transmission into neutral.

3.
As a preliminary adjustment, turn idle mixture

screws lightly to seat and back out 1-1/2 turns.

CAUTION: Do not turn idle mixture screw

tightly against seat or damage may result.

4.
With engine running (choke wide open) adjust idle
speed screw to specified idle speed, (automatic

transmission in drive, synchronized transmission in

neutral).

5. Adjust idle mixture screw to obtain highest steady

vacuum at specified idle speed.

NOTE:
On air conditioned vehicles, turn air

conditioning to the "on" position and hold the

hot idle compensator valve closed while adjust-

ing idle speed and idle mixture screws.

NOTE:
On Rochester BV carburetors the idle

mixture screw should be turned out 1/4 turn

from the "lean roll" position. The definition

of "lean roll" point is a 20 to 30 rpm drop

in engine speed obtained by leaning the idle

mixture.

6. Repeat Steps 4 and5 as needed for final adjustment.

NOTE:
If necessary, final adjustment of the \

carburetor may be made with the air cleaner

installed.

7. Turn engine off, remove gauges and install air

clearer.

mounting brackets.

CLUTCH LINKAGE ADJUSTMENT

There is one linkage adjustment (clutch fork push rod

or pedal push rod) to compensate for all normal clutch

wear.

The clutch pedal should have
1-1/4"
free travel (meas-

ured at clutch pedal pad) before the throwout bearing en-

gages the clutch diaphragm spring levers. Lash is re-

quired to prevent clutch slippage which would occur if the

bearing was held against the fingers and to prevent the

bearing from running continually until failure.

Chevrolet Linkage Adjustment (Fig. 1}

With Nuts (A) & (B) loose on Rod (D)
&
before installa-

tion of Clutch Pedal Return Spring
(E),
apply approximately

5 lbs. load in direction of arrow (F) to eliminate clear-

ance between throwout bearing and clutch fingers. Move

Rod (D) in direction of arrow (G) until Clutch Pedal Arm

makes contact with Bumper Stop on instrument panel

brace. Run Nut (B) toward Swivel until dimension (X) is

9/32". Tighten Nut (A) to lock Swivel (C) against Nut (B).

Install Clutch Pedal Return Spring (E).

The foregoing procedure will provide a free pedal

travel of 1" to
1-1/2"
measured on a perpendicular from

the crown of the, pedal pad to the bare metal toe pan.

Chevelle Linkage Adjustment (Fig. 2)

1.
Disconnect spring between cross shaft lever and

clutch fork.

at square wrench area) until it is free of clutch fork.

4.
Hold the clutch fork rearward to move throwout

lightly against clutch release fingers, then adjust rod

length until rod just touches ,its seat in the fork.
5.
Adjust locknut to obtain approximately 3/16" clear-

ance between nut and rod sleeve end.

6. Turn the rod with wrench, until the nut just comes in

contact with rod sleeve end, then hold the rod with

wrench and tighten locknut.

7.
Check free pedal travel at pedal (1" to
1-1/2"
is

proper clearance). Readjust if necessary.

chined flat "B". (Shorten push rod to increase pedal

lash).

2.
Hold push rod at flat "B" and tighten locknut "A".

3.
Recheck pedal free travel.

NOTE: A measurement of approximately 3/16"

between push rod and its seat in fork will give

required pedal free travel.

V-8 Models

The eight cylinder linkage has a two-piece clutch fork

push rod (fig. 3). Adjust clutch pedal free travel by turn-

ing the adjusting rod portion of the push rod to obtain apr

proximately 3/16" clearance between clutch fork and end

of rod, ttien tighten locknut to 8-12 lbs. ft. and check free

travel at pedal. Pedal free travel on all models should

be 1" to
1-1/2".

Refer to fig. 1 and the following procedure:

1.
Disconnect pedal return spring.

2.
With Nuts (A) and (B) loose on Rod (D) apply push

hard load in direction of arrow (F) to eliminate

clearance between throwout bearing and clutch

fingers.

3.
Run Nut (B) towards Swivel (C) until dimension (X)

is 3/8" to 7/16".

4.
Tighten Nut (A) to lock swivel against Nut (B).

5.
Connect pedal return spring and check pedal free

travel for
1-1/4"
minimum to 2" maximum.

6. Check every 3,000 miles.

7.

Replacement

In the event replacement is necessary use the following

procedure.

1.
Remove seat separator (console) assembly.

2.
Remove shift lever seal retainer and slide seal up

on lever.

3.
Remove shift lever knob, and the 2 lever to bracket

retaining nuts and remove the lever assembly.

4.
Replace blocker cable - thread new cable up through

lever and MT" handle and install cable retainer

through access slot. Adjust retainer to hold blocker

end .010/.020" above lever bracket surface, then lock

and cut off excess cable.

5.
Reverse Steps 1, 2 and 3 to install.
Figure 3M shows the adjustment and lubrication proce-

dure for the mechanism. This Figure applies to both

models of lever assemblies.

NOTE: If, for any reason, the cable assembly

is removed from the handle, it is difficult to in-

stall without rework. This is due to the fact that

the extra length of the cable is trimmed after

assembly and, therefore, it is almost impossible

to get the shortened cable to enter the cable hole

in the cylindrical retainer.

If new service cable assemblies are not available, the

original part can be re-used by butt soldering a 2.00 inch

piece of small wire to the cable end. Trim the solder

joint so that it will pass through the hole in the retainer.

After assembly, trim off the excess wire as shown in

Figure 3M.

Adjustment

1.
With set screw loose, assemble cable through hole

in cylindrical retainer above handle.

GENERAL DESCRIPTION

The case
and
converter housing
of the two
speed alumi-

num Powerglide Transmission
is a
single case aluminum

unit. When
the
manual control
is
placed
in the
drive
po-

sition,
the
transmission automatically shifts
to low
gear

for initial vehicle movement.
As the car
gains speed
and

depending
on
load
and
throttle position,
an
automatic shift

is made
to
high gear.
A
forced downshift feature
pro-

vides
a
passing gear
by
returning
the
transmission
to low

range.

The
oil
pump assembly
is a
conventional gear type
and

the
oil
pump housing
is of the
large diameter type acting

as
the
front bulkhead
of the
transmission.
The
torque

converter
is a
conventional three element welded design

bolted
to the
engine flywheel which drives through
a
two-

speed planetary gearset.
The
high clutch assembly
is

typical
of the
designs used
in
this type transmission.
The

aluminum Powerglide uses
an
output shaft mounted
gov-
ernor which requires
a
hole through
the
output shaft.
The

reverse clutch assembly
is a
multiple disc type clutch.

The steel plates
are
splined directly
to the
case while
the

face plates
are
splined
to the
internal
or
ring gear.
The

clutch piston operates within
the
rear portion
of the
case.

The internal diameter
of the
pistoh
is
sealed to
an
integral

hub portion
of the
case rear bulkhead.
The
outside
dia-

meter
is
sealed
to a
machined portion
of the
case.
The

piston
is
hydraulically applied
and is
released
by
separate

coil springs.
The
valve body assembly
is
bolted
to the

bottom
of the
transmission case
and is
accessible
for

service
by
removing
the oil pan
assembly.
The
valve

body consists
of an
upper
and
lower body located
on
either

side
of a
transfer plate.
The
vacuum modulator
is lo-

cated
on the
left rear face
of the
transmission case.
The

modulator valve bore
is
located
in the
upper valve body.

MAINTENANCE
AND
ADJUSTMENTS

OIL LEVEL CHECK

The transmission
oil
level should
be
checked period-

ically
as
recommended
in
Section
0. Oil
should
be
added

only when level
is on or
below
the
"ADD" mark
on the dip

stick with
oil hot or at
operating temperature.
The oil

level
dip
stick
is
located
at the
right rear
of the
engine
compartment. Fill with
oil
specified
in
Section
0.

In order
to
check
oil
level accurately,
the
engine should

be idled with
the
transmission
oil hot and the
control

lever
in
neutral (N) position.

It
is
important that
the oil
