INSPECT COOLING SYSTEM
HOSES AND LINES
Inspect the cooling system hoses
for evidence of cracking or extreme
weathering.
Replace cracked hoses.
Check for leaking or porous hoses
and tighten or replace.
Make sure all supporting brackets
for hoses are in place and that the
hoses are properly installed in the
brackets.
Inspect the radiator core and tanks
for seepage or
leaks.
Check all fittings to see that they
are tight and in good
condition.
Examine the hoses at the fittings for
cuts or weakness. Repl.ace any hose
in questionable condition.
REPLACE RADIATOR COOLANT
Refer to Part 19, Maintenance
Schedule, for recommended fre-
quency of service.
To drain the radiator, open the
drain cock located at the bottom of
the radiator and remove the cylinder
block drain plug(s). The 6-cylinder
engine block has one drain plug locat-
ed at the right rear of the cylinder
block ahead of the. starter (Fig. 1 ).
The V -8 engines have a drain plug on
each side of the cylinder block (Fig.
2).
To fill the cooling system; close the
drain cock. Install the block drain
plug(s). Disconnect the heater
outlet hose at the water pump to
bleed or release trapped air in
the system. When the coolant begins
to escape, connect the heater outlet
hose.
Add radiator inhibitor of approved
specifications.
Operate the engine until normal
operating temperature
has
been
reached. After the. initial fill, the

coolant level will drop approxi-
mately one quart after the engine
has been operated about 20 min-
utes at 2,000 rpm. This is due to
the displacement of entrapped
air. Add more coolant to fill the
radiator supply tank.
CHECK ENGINE COOLANT LEVEL
The coolant level should be kept
one inch below the filler neck
opening.
INSPECT FUEL LINES AND FILTER
FOR LEAKS
With the engine off, examine the
fuel ·line connections for wetness or
washed or stained areas that might
indicate a fuel leak. Start the engine
and observe all the connections for
fuel seepage. Tighten or replace fuel
lines as necessary.
REPLACE FUEL FILTER
Refer to Part 19, Maintenance
Schedules,
for
recommended
frequency of filter replacement.
The in-line fuel filter used on V-8
engines 250
CID
2V six cylinder, and
the 250
CID
1 V six cylinder engine
equipped with air-conditioning is of
one-piece construction and cannot be
cleaned. Replace the filter (and gasket
if so equipped) if it becomes clogged
or restricted. Otherwise, replace it at
the interval specified in the mainten-
ance schedule.
IN-LINE FILTER REPLACEMENT
-VB
1. Remove the air cleaner.
2. Loosen the retaining clamp se-
curing the fuel inlet hose to the fuel
filter.
3. Unscrew the fuel filter from the
carburettor and discard the gasket, if
so equipped. Disconnect the
·
fuel
filter from the hose and discard the
retaining clamp.
4. Install a new clamp on the inlet
hose and connect the hose to the
filter. Place a new gasket (if
used)
on
the new fuel filter and screw the filter
into the carburettor inlet port.
Tighten the filter.
5. Position the fuel line hose clamp
and crimp the clamp securely.
6. Start the engine and check for
fuel leaks.
