If the effort required to depress the clutch pedal
becomes excessive,
or
the linkage begins to squeak
or
grunt, release bearing sleeve, and fork fingers
and pivot should be relubricated with a thin film
of Multi-Purpose Grease NLGI Grade 2, E.P. or
with Multi-Mileage Lubricant, Part Numer
2525035 or equivalent.
To gain access
to
this area, remove the clutch
inspection plate at the bottom of the clutch
housing, the clutch fork boot, and fork.
Apply lubricant
to
the points of contact on fork
pivot, fork fingers, fork pads on sleeve and sleeve
cavity. (Fig. 19). The clutch drive lugs should be
relubricated only with a high temperature adhesive
grease such as Multi-Mileage Lubricant, Part
Number 2525035 or equivalent, to minimize the
possibility zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA

COOLING
SYSTEM
The cooling system of all cars is protected
against corrosion and freezing as they leave the
factory. A permanent type anti-freeze is added to
provide protection to .-20 degrees F. Higher per-
centages of anti-freeze must be added where temp-
eratures below -20 degrees
F.
are anticipated.
All engines are equipped with 185 degree ther-
mostats and only permanent (ethylene glycol) type
anti-freeze should be used. Plain water or alcohol-
base anti-freezes should not be used because their
boiling points are too low.
Inspect coolant level every month and maintain
coolant level at approximately 1-1/4 inches below
the bottom of the filler neck. Overfilling will
cause loss through the overflow tube.
Once a year, preferably in the fall, the cooling
system should be drained and refilled. This drain-
ing and refilling procedure, however, need not be
performed until the fall following the vehicle's first
full year operation. Drain zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA

engine cooling
sys-
tem by removing drain plugs in sides of cylinder
block and opening drain cock in lower radiator
tank. On 6-cylinder engines, remove the single
drain plug in right side of engine and open drain
cock in lower radiator tank.
Discard old
solutions.
Flush the system thoroughly with water. If there
is
an indication that the system contains a consid-
erable amount of sediment, use a reliable cooling
system cleaner to loosen the sediment. Rinse thor-
oughly to remove deposits.
At this time, check water pump belt tension and
check hose connections for tightness. Refill cooling
system with clean soft water and a suitable high,
quality ethylene glycol anti-freeze in sufficient
quantity to provide full protection for the lowest
anticipated temperature, but never less than zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA
44
percent of the cooling system capacity to ensure
adequate protection against corrosion and boiling.
A convenient ratio of
50%
ethylene glycol type
anti-freeze and
50%
water will provide protection
to -34 degrees
F.
If it becomes necessary to add coolant during
the cold weather season, be sure the system con-
tains sufficient anti-freeze to provide protection at
least to
-20
degrees
F.
A suitable high quality
permanent type anti-freeze, available under Part
Number 2932531 or equivalent, should be used.
When using a high-quality anti-freeze coolant, it is
not necessary to add additional rust inhibitors
or
an anti-rust type product.
If the vehicle is equipped with air conditioning,
the cooling system must contain anti-freeze coolant
all year-round. This is necessary because in the
reheat cycle, cold, refrigerated air passes through
the heater core. Anti-freeze is necessary to prevent
coolant in the heater core from freezing in hot
weather when the air conditioner
is
being used.
