oil temperature CHEVROLET CORVETTE 1964 Owners Manual

The ammeter shows the rate at which the battery is being charged or discharged. The Delcotron charg­
ing system is equipped 'with a regulator which con­
trol s the charge acco rding to battery requirements.
When the Delcotron generator is supp lying more
than the curre nt demand, the ammeter will show the
chargi ng rate while a disc harg e will be shown if
the
current demand is more than the Delcotron output.
With the battery fully charged , the charging rate will be 1m-\', thus giving an indication of battery condition.
OIL PRESSURE
GAUGE
...
The oil pressure gauge indicates the pressure at which
oil is being delivered to the various parts of the en·
gine requiring lubrication. Pressures registered by the
AMMETER
•
gauge
may vary acco rding to outside air temperatures or weight of oil being used. Oil pressure of a cold en­
gine being operated at a given speed will be somewhat
higher than when the engine is at normal operating
temperature at the sam e speed. Prolonged high speed operation on a hot day at the giv en speed will result in somewhat lower oil pressure readings. Readings of 30 to 40 psi may be considered normal during moderate road speeds of 35 to 40 mph with the en­
gine at proper operating temperature. Gauge read­
in gs whi ch are consistently high or low under these
co nCIitions may ind i cate lubrication system and/or
engine malfunctions.

FUEL
GAUGE
..
The ele ctr ically o p erated fuel gauge will indicate
th e amoun t o f fuel in the lan k when th e ig nition
switc h i s turned on. W hen the ignition switch is
turned off, the nee dle will not necessar ily retur n to the em pty mark.
TEMPERATURE
GAUGE
..
Showing engin e coo lant temperature, gauge readings w ill vary with air temp eratur e and operating condi­
tions. Hard driving or prolonged idling in very hot
weather may produc e above normal readings. The ignitio n swit ch must be o n [or accur ate r eadings.
CLOCK
..
Resetting the dock provides a utomatic regulat io n
providing ther e is an error, either fast o r slow, of at
lea st 3 minu tes. No regulat ion will be introd uced if
the clock is reset for an error of less than 3 minutes. When resetting, pull out the small knob and turn in the direction in whi ch you wi sh to set the hands­clockwise if the clock is slow, counterclockwi se if the clo ck is fast. Do not move the hand s pas t the cor­
rect time. Your clock should be cleaned and oiled periodi cally.
The courtesy lights beneath the o u ter
en ds of the dash p a nel, as well as the Sport Coupe dome light and the Con-
COURTESY vertible r ear compartment light, will
LIGHTS come on when eithe r door is opened. They may a lso be lighted by turning the headlight switch fully counter­clockwise past the slight resi stan ce.

Fuel System Requirements The high performance V-8 engine in your Corvette is designed to operate efficiently on premium type gasolines. See page 43 for
octane requirements. Use of regular grade gasolines in higher
performance engines may result in potentially dangerous engine
detonation.
FUEL
FILLER
CAP In some areas, grades of gasolines may be encountered which result
in severe detonation. Should this occur consult an authorized Chevro­
let
Dealer so that adjustments can be made to eliminate this detona­
tion or reduce it to a safe level.
Lift tip the Corvette emblem on the rear deck to reach the fuel filler cap. II the cap is lost be sure to replace it with a vented cap.
In
all cases excessive engine detonation, or knocking, should be
avoided in order to prevent possible eng ine damage .

SAE
30 or IOW-30 is recommended when most o[
the driving is at high speeds and/or at temperatures
above gO°F . For continued reliability and perform- ance
from your Corvette
engine, it
is recommended
that you use an oil whic h, according to the label on the can, is (I) intended for service MS and (2) passes car makers' tests or meets General
Motors Standard GM 4745 -M.
Follow the accompanying vicosity
and change interval recommenda­
tions
and check the oil leve l (with
engine hot) on the dipstick regu­
larly. Keep oil level between the
FULL and ADD marks, by adding oil when level is at or below ADD mark. It is not
necessary to keep the level at the FULL mark. DO NOT OVERFILL.

Parking Brake Cables and Linkage -Every 6,000 miles-Apply lubricant specified in Note I, page 39.
STEERING GEAR
Every 36,000
miles-Check lubricant level as follows: l. Remove the forward and the outboard cover at­taching screws. 2. Inject steering gear lubricant into the forward
cover attaching screw hole until
lubricant begins
to come out of the outboard screw hole. 3. Replace both screws.
POWER STEERING PUMP
Check fluid level
in pump reservoir every 6,000 miles
or 6 months. Fill as required with Automatic Trans­
mission fluid "Type A" with AQ-ATF-A mark. Oil should be at operating temperature and wheels in straight ahead position when checking or filling
operation is performed to ensure against overfilling.
FRONT SUSPENSION
Every 6,000 miles
or 6
months, lubrica te 4 fit­tings (2 fittings on each side), with lubricant specified in Note I, page 39. I
STEERING LINKAGE
Ev ery 6,000 miles or 6 months-lubricate fittings
shown below with lubricant specified in Note I ,
page 39.
Manual-Fitting at each tie rod end and at relay rod (5 fittings) .
Power
-Fitting at each tie rod end and at power
steering valve adapter and cylinder (6 fittings).
