COOLING SYSTEM
WARNING: TAKE CARE TO AVOID THE RADIA-
TOR COOLING FAN WHENEVER THE VEHICLE
HOOD IS RAISED. IF YOU MUST WORK NEAR THE
FAN, DISCONNECT THE FAN MOTOR LEAD.
INSPECTION
WARNING: WHEN REMOVING
THE RADIATOR
CAP,
CARE SHOULD BE TAKEN TO PREVENT
SCALDING FROM HOT PRESSURIZED COOLANT.
Coolant protection checks should be made every 12
months (prior t o the onset of freezing weather, where
applicable). I f coolant i s d i r t y or r u s t y i n appearance,
the
system should be drained,flushed a n d refilled
w i t h fresh coolant.
Check r a d i a t o r cap for proper vacuum sealing and
operation. Use caution w h e n r e m o v i n g the radiator
cap t o avoid contact w i t h hot coolant or steam. Place
a cloth over t h e cap, t u r n to t h e first stop, (do n o t
press down), pause
t o allow pressure t o release
t h r o u g h the overflow tube,then press down and t u r n
counterclockwise t o remove cap. Check face o f radia-
tor and a i r c o n d i t i o n i n g condenser for any accumula-
t i o n of bugs, leaves, etc. Check t u b i n g a t coolant
reserve t a n k and radiator. Inspect entire system for
leaks.
Y o u r cooling system has a 50/50 solution o f a n t i -
freeze and w a t e r from t h e factory. T h i s is t h e recom-
mended solution for most operating temperatures
and provides good corrosion protection.
F a i l u r e t o follow anti-freeze concentration and re-
placement recommendations or f a i l u r e t o use a n t i -
freeze formulated t o prevent corrosion o f a l l cooling
system metals, may r e s u l t i n r a d i a t o r plugging. The
result is engine overheating or cooling system leaks,
such as a t core hole plugs, r e s u l t i n g i n loss of cool-
ant.
RADIATOR CAP
The r a d i a t o r cap m u s t be f u l l y tightened i n order
to provide a good seal w i t h the radiator f i l l e r neck.
T h i s prevents loss o f coolant and ensures t h a t coolant
w i l l r e t u r n t o the r a d i a t o r f r o m the coolant reserve
t a n k . The v e n t valve and i t s seat can become con-
t a m i n a t e d w i t h coolant sediment etc. The valve and
seat should be carefully cleaned i f :
(1) The system w i l l not go under pressure.
(2) The coolant reserve bottle gains coolant abnor-
m a l l y .
(3) The top r a d i a t o r hose collapses o n cool-down.
DRAIN, FLUSH AND FILL
D r a i n , flush, a n d f i l l the cooling system at t h e
mileage or t i m e i n t e r v a l s specified i n t h e Mainte-
nance Schedule i n t h i s Group. I f t h e solution is d i r t y
or r u s t y or contains a considerable amount o f sedi-
m e n t , clean a n d flush w i t h a reliable cooling system
cleaner. Care should be t a k e n i n disposing o f t h e
used engine coolant f r o m y o u r vehicle. Used coolant,
i n d i s c r i m i n a t e l y discarded, can present a p r o b l e m t o
the environment. Contact y o u r dealer, service s t a t i o n
or governmental agency t o f i n d o u t where used cool-
ant can be properly discarded i n y o u r area.
Refer t o Group 7, Cooling System for t h e proper
d r a i n , flush a n d f i l l procedures.
HOSES AND FITTINGS
Inspect t h e hose f i t t i n g s for looseness a n d corro-
sion. Inspect t h e hoses for brittleness and cracks.
T h o r o u g h l y inspect t h e hose ends t h a t are slipped
onto nipples.
E n g i n e performance m a y be adversely affected b y
air leaks i n t o such u n l i k e l y places as the heater a n d
air conditioner control v a c u u m hoses, coolant hoses
or t h e power brake booster v a c u u m hose.
ENGINE AIR CLEANER
The engine a i r cleaner should be replaced every 48
000 k m (30,000 miles) under n o r m a l d r i v i n g condi-
tions. W h e n t h e vehicle is frequently operated i n
dusty conditions t h e a i r cleaner should be replaced
and the wrapper cleaned as required.
Remove cleaner assembly, remove paper element
(Fig. 3). Clean f i l t e r element by b l o w i n g d i r t out gen-
t l y w i t h compressed a i r (Fig. 4). Direct a i r from i n -
side o u t , a n d keep nozzle t w o inches away
f r o m
element to avoid damage. I f the f i l t e r element is sat-
u r a t e d w i t h o i l for more t h a n 1/2 i t s circumference
replace t h e f i l t e r element a n d wrapper

Check t h e rest o f t h e crankcase v e n t i l a t i n g system
for proper operation.
Do not immerse paper element i n l i q u i d .
On vehicles equipped w i t h a heated a i r system, do
not
