Refrigerant Charging Procedure
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
4. Refrigerant Charging Proce-
dure
A: PROCEDURE
CAUTION:
•During operation, be sure to wear protective
goggles and protective gloves.
•Before charging the refrigerant, evacuate the
system to remove small amounts of moisture
remaining in the system.
The moisture in the system can be completely
evacuated only under the minimum vacuum
level. The minimum vacuum level affects the
temperature in the system.
•The list below shows the vacuum values nec-
essary to boil water at various temperatures. In
addition, the vacuum levels indicated on the
gauge are approx. 3.3 kPa (25 mmHg, 0.98 inHg)
lower than those measured at 304.8 m (1,000 ft)
above sea level.
1) Close the valves on low-/high-pressure sides of
the manifold gauge.
2) Install the low-/high-pressure hoses to the corre-
sponding service ports on the vehicle.
3) Connect the center hose of the manifold gauge
set with the vacuum pump.
4) Carefully open the valves on the low-/high-pres-
sure sides to activate the vacuum pump.
5) After the low-pressure gauge reaches 100.0 kPa
(750 mmHg, 29.5 inHg) or higher, evacuate the
system for approx. 15 minutes. (Continue evacua-
tion).
6) After 15 minutes of evacuation, if the reading
shows 100.0 kPa (750 mmHg, 29.5 inHg) or higher,
close the valves on the both sides to stop the vac-
uum pump.

Service limit:
Maximum load: 9.22 N (0.94 kgf, 2.07 lb) or
less
NOTE:
•A rather higher value may be indicated when pul-
ley starts turning.
•Measure the load during rotation to make a judg-
ment.
3. HYDRAULIC PRESSURE
NOTE:
•To measure hydraulic pressure correctly, be sure
to complete all the items in “INSPECTION”, prior to
performing the measurement. SPECTION, General Diagnostic Table.>
•Do not leave the valve of pressure gauge closed
or hold the steering wheel at lock for 5 seconds or
more in any case, this can damage the oil pump.
•Before attaching a pressure gauge, place a
wastecloth at locations where fluid can be expected
to spill. Wipe off any spilt fluid completely after the
measurement.
1) Regular pressure measurement

(4) Using the gasket (Part No. 34621AC021)
and bolt (Part No. 34620AC010), install the ST2
to pump instead of pressure hose.
(5) Install the ST3 to the end of pressure hose
which is removed from pump.

A: SPECIFICATION
B: INSPECTION
1) Check the power steering fluid for deterioration
or contamination. If the fluid is highly deteriorated
or contaminated, drain it and refill with new fluid.
2) Check the joints and units for oil leakage. If any
oil leaks are found, repair or replace the applicable
part.
3) Inspect the fluid level of reservoir tank with vehi-
cle on level surface and engine stopped.
If the level is at “MIN. ” point or below, add fluid to
keep the level in the specified range of the indica-
tor. If at “MAX. ” point or above, drain fluid by using
a syringe or the like.
(1) Check at power steering fluid temperature
20°C (68°F); read the fluid level on the “COLD”
side.
(2) Check at power steering fluid temperature
80°C (176°F); read the fluid level on the “HOT”
side.
C: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the crossmember support.
3) Remove the pipe joint in the center of gearbox,
and connect the vinyl hose to the pipe and joint.
Wipe fluid off while turning the steering wheel.
4) Add the specified fluid to reservoir tank at “MAX”
level.
5) Continue to turn the steering wheel slowly from
lock to lock until the bubbles stop appearing on oil
surface while keeping the fluid at the level in the
Step 4).
6) If the steering wheel is turned in a low fluid level
condition, air will be sucked into the pipe. If sucked,
leave it about half an hour and then do the step 5)
again.
7) Start the engine and let it idle.
8) Continue to turn the steering wheel slowly from
lock to lock again until the bubbles stop appearing
on oil surface while keeping the fluid at the level in
Step 4).
Normally bubbles will stop appearing after turning
the steering wheel from lock to lock three times.
9) In case bubbles do not stop appearing in the
tank, leave it about half an hour and then do the
step 4) all over again.
10) Lower the vehicle, and then idle the engine.
11) Continue to turn the steering wheel from lock to
lock until the bubbles stop appearing and change of
the fluid level is within 3 mm (0.12 in).
12) In case the following happens, leave it about
half an hour and then do step 8) to 11) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the
fluid.
(3) Grinding noise is generated from oil pump.
13) Check the fluid leakage after turning steering
wheel from lock to lock with engine running.

A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en
