LUBRICATION 0-16

Every 12,000 miles (more frequently*, depending on

severity of service, if vehicle is used to pull trailers,

carry full loads during high ambient temperatures,

operate in mountainous terrain or operate under other

severe conditions--Remove fluid from the transmission

sump and add one and a half quarts of fresh fluid for

Camaro and Chevy II and two quarts for Chevrolet,

Chevelle, and Corvette. Operate transmission through all

ranges and check fluid level as described above.

•Except if vehicle is equipped with transmission pro-

vided in heavy duty service options. If so equipped,

drain converter and pump every 12,000 miles and add

approximately seven and a half quarts of fresh fluid

for Chevy II and nine quarts for Chevrolet and Chevelle.

TURBO HYDRA-MATIC

Lubrication. recommendations for the Turbo Hydra-

Matic are the same as outlined for the Powerglide

transmission except for fluid capacity and filter change

listed below.

After checking transmission fluid level it is important

that the dip stick be pushed all the way into the fill tube.

Every 12,000 miles — after removing fluid from the

transmission sump, approximately 7 1/2 pints of fresh

fluid will be required to return level to proper mark on

the dip stick.

Every 24,000 miles, or at every other fluid change--

the transmission sump strainer should be replaced.

FRONT WHEEL BEARINGS

It is necessary to remove the wheel and hub assembly

to lubricate the bearings. The bearing assemblies should

be cleaned before repacking with lubricant. Do not pack

the hub between the inner and outer bearing assemblies

or the hub caps, as this excessive lubrication results in

the lubricant working out into the brake drums and

linings.

Front wheels of all passenger car models are equipped

with tapered roller bearings and should be packed with a

high melting point water resistant front wheel bearing

lubricant whenever wheel and hub are removed.

CAUTION: "Long fibre" or "viscous" type

lubricant should not be used. Do not mix wheel

bearing lubricants. Be sure to thoroughly clean

bearings and hubs of all old lubricant before

repacking.

The proper adjustment of front wheel bearings is one

of the important service operations- that has a definite

bearing on safety. A car with improperly adjusted front

wheel bearings lacks steering stability, has a tendency to

wander or shimmy and may have increased tire wear.
The adjustment of these bearings is very critical. The

procedure is covered in Section 3 of this manual under

Front Wheel Bearings—Adjust,

MANUAL STEERING GEAR

Check lubricant level every 36,000 miles. If required,

add EP Chassis Lubricant.

POWER STEERING

On models equipped with power steering gear, check

fluid at operating temperature in pump reservoir. Add

GM Power Steering Fluid, or, if this is not available, use

Automatic Transmission Fluid "Type A" bearing the

mark AQ-ATF followed by a number and the suffix letter

'A'
to bring level to full mark on dip stick.

AIR CONDITIONING

After the first 6,000 miles, check all hose clamp

connections for proper tightness.

Every 6,000 miles check sight glass under the hood,

after the system has been in operation for several

minutes. Sight glass should be clear but may, during

milder weather, show traces of bubbles. Foam or dirt

indicate a leak which should be repaired immediately.

BRAKE MASTER CYLINDER

Check level every 6,000 miles and maintain 1/4" below

lowest edge of each filler opening with GM Hydraulic

Brake Fluid Supreme No. 11.

PARKING BRAKE

Every 6,000 miles, apply water resistant lube to park-

ing brake cable, cable guides and at all operating links

and levers.

CLUTCH CROSS-SHAFT

Periodic lubrication of the clutch cross shaft is not

required. At 36,000 miles or sooner, if necessary;

remove plug, install lube fitting and apply CHASSIS

LUBRICANT.

CHASSIS LUBRICATION

For chassis lubrication, consult the lubrication chart.

It shows the points to be lubricated and how often the

lubricant should be applied.

The term "chassis lubricant" as used in this manual,

describes a water resistant EP chassis grease designed

for application by commercial pressure gun equipment.

and its resistance is decreasing. In the HI FRONT

position, two thermistors (the master delay and high

blower delay thermistors) are warming. The air

door is in recirculation position until the engine

coolant reaches 75 degrees.

2.
The coolant reaches then 75 degrees and the thermal

vacuum valve opens applying vacuum to the air door

to admit outside air (unless the temperature dial is

set for cooling). Ram air will flow through the sys-

tem when the car is moving.

3.
Next, the master delay thermistor attains the tem-

perature at which it will pass sufficient current to

close the circuit through the master delay relay.

The relay circuit powers the blower motor at 9 volts.

4.
If the control is in the HI FRONT position, the high

blower delay thermistor will close the circuit

through the high blower relay which supplies full

available voltage to the blower motor. This function

occurs after the master delay thermistor has taken

effect because the high blower delay thermistor

uses the master delay type thermistor with a 10 ohm

1/4 watt resistor connected in
.
series. The nigh

blower delay thermistor must then warm to a higher

temperature than the master delay thermistor before

its resistance (plus that of the 10 ohm resistor)

drops enough to actuate the high blower relay.

5. If the controls are set for DE ICE, full outside air

and full voltage to the blower motor are effective

immediately regardless of temperatures or elapsed

times o

In accomplishing automatic control, the system follows

three steps to transform an electronic signal into me-

chanical energy through which the control is achieved.

Electronic Circuit

Two temperature sensors (Thermistors), and the duct

potentiometer connected in series, are located so as to

sense the temperature of the outside air, inside air and

system output air. The resistance of each sensor will

vary according to its temperature. The control head

temperature dial varies in resistance as it is adjusted by

the operator to suit his comfort requirements. The

resistance of the temperature dial control is applied

directly to the amplifier and is not in series with the

sensors and duct potentiometer. Thus temperature dif-

ferences in the sensor string plus the requirements fed

into the system by the operator cause changes in total

circuit resistance which allow a varying voltage flow

through the circuit.

Changing the Electronic Signal to Electrical Voltage

This minute voltage flow from the sensor string -

temperature dial circuit - is fed into the amplifier where

it is transformed into a usable amplifier output voltage,

the strength of which is determined by the strength of the

original amplifier input signal. This voltage is then

supplied to the transducer.

Changing the Electrical Voltage to a Vacuum Signal

Amplifier output voltage, varying according to tem-

perature requirements, is converted by the Transducer

into a modulator transducer output vacuum. This modu-

lated vacuum is applied to the Power Servo.

Changing the Vacuum Signal to Mechanical Energy

The Power Servo, controlled by the modulated Trans-
ducer output vacuum, operates the vacuum electrical and

mechanical components of the system as required to

provide automatic control of system operation.

Other major system components are mounted con-

ventionally in the engine compartment. Underhood com-

ponents and system airflow remain much the same as in

the Four-Season system except for the addition of the

automatic control provisions. The system operates on

100%
outside air, a mixture of outside and inside air, or

100%
recirculated air depending on the demands of the

system. The diaphragm operated .air selector door will

modulate outside air to the system during maximum air

conditioning requirements when the control unit is in

"Hi Front" position. Control of the blower is also com-

pletely automatic and dependent upon system demands.

Controls

The Comfortron controls the Chevrolet air conditioner

and heater in such a precise manner that the automobile

temperature remains relatively constant under all driving

conditions. By adjusting the thumb wheel on the Control

Head to any temperature desired between 65° and 85° F.

(See Figure 27) the automatic system will adjust the in-

car temperature even though the outside weather condi-

tions may vary considerably. The system will provide

maximum capacity for heating or cooling until the in-car

temperature reaches the pre-set Control Head Tempera-

ture. Where cooling is required, the system will start

immediately upon being turned "ON". During marginal

ambient temperatures the system will not always start

at the highest blower speeds of the control setting.

Therefore, occasionally the system can't be heard

starting*

Five over-riding functions are available so that special

conditions can be handled. Each Control Head function

will be discussed in detail below:

"Off" Position

In the "Off" position, the blower is turned off and the

outside air door is closed. No outside air should enter

the automobile.

"Lo Front" Position

The blower has five low to moderate speeds; Hi, M3,

M2,
M1 and Lo. The blower voltage will shift as directed

by the automatic controls. The "Lo Front" position

provides a quieter mode of automatic operation due to

reduction of blower noise.

"Hi Front" Position

The "Hi Front" position provides five high blower

speeds as called for by the automatic controls: The use

of the "Hi" blower speed results in a rapid cool down in

hot weather and rapid heating during cold weather. As

the in-car temperature approaches the temperature set-

ting on the Comfortron Control Head, the blower speed

will change, provided mild outside temperatures are

experienced. During very hot or cold weather, the blower

will reduce its speed only to the point where it is still

capable of maintaining the correct inrcar temperature.

"Rear" Position

The "Rear" position provides five high blower speeds.

The automatic controls select these speeds and blend the

discharge air to the proper temperature. By the use of

high blower speeds, increased airflow is obtained for

better rear seat passenger comfort.

are certain procedures, practices and precautions that

should be followed to prevent costly repairs, personal

injury or damage to equipment. For this reason it is

strongly recommended that the preceding information in

this section be studied thoroughly before attempting to

service the sytem.

Great emphasis must be placed upon keeping the sys-

tem clean. Use plugs or caps to close system components

and hoses when they are opened to the atmosphere. Keep

your work area clean.
