CLEARANCE
Valve clearance
adjustment
is
performed
with
the
engine
not running
The initial
adjust
ment is made while the
engine
is
cold
Remove the air cleaner Unbolt
and remove
the camshaft cover
Each valve must be ad
justed
with the valve
completely
closed that
is
the rocker
arm
should be at the base
Ilowest
point
of the cam lobe Loosen
the
locking
nut and turn the
adjusting
screw
until
the
specified
clearance is obtained
as checked
with a fuel
gauge between
the rocker
arm
and
camshaft
Straighten
the
locking
nut
Repeat
this
procedure
on
each valve
turning
the
engine
over bv
hand to
position
each valve as
necessary Temporarily replace
the camshaft
cover
with two or three bolts and warm
up
the
engi
ne
Remove the cover
and recheck the
valve clearance
according
to
the
warranty
cer
tilicates
Readjust
as
necessary
Replace
the
camshaft cover
using
a new
gasket
if the old
gasket
appears
tlattened

COOLANT
Nissan
Long
Life Coolant
LL C is an
ethylene glycol
base
product
con
taining
chemical inhibitors to
protect
the
cooling
system
from
rusting
and
corrosion
The
L L
C does not contain
any glycerine
ethyl
or alcohol
It will not
evaporate
or
boil
away
and
can
be used
with either
high
or
low
temperature
thermostats It
flows
freely
tran
sfers heat
eniciently
and will
not
clog
the
passages
in the
cooling
system
The L L C
must not be mixed with
other
product
This
coolant
can
be used
throughout
the seasons of
the
year
Whenever
any
coolant is
changed
the
cooling
system
must be tlushed and relilled
with a
new
coolant Check the level
COMPRESSION
When it becomes
necessary
to check
cylinder
compression
it is essential
to remove an
spark plugs
The
purpose
of this test is to
determine whether
there is excessive
leakage
past
the
piston
rings
head
gasket
etc To test
the
engine
should be heated
to the
operating
temperature
and throttle and
choke
valves
opened
Cylinder compression
in
cylinders
should not
be less than 80cf
of the
highest reading
