8. Aluminum Wheel
A: INSPECTION
Inspection for aluminum wheels is basically the
same as the one for steel wheels. However, check
the rim flange for cracks or damage, and replace
(not repair) aluminum wheel if air leakage is found.
B: PRECAUTIONS
Aluminum wheels are easily scratched. To main-
tain their appearance and safety, do the following:
1) Do not damage aluminum wheels during
removal, disassembly, installation, wheel
balancing, etc. After removing aluminum wheels,
place them on a rubber mat, etc.
2) While vehicle is being driven, be careful not to
ride over sharp obstacles or allow aluminum
wheels to contact the shoulder of the road.
3) When installing tire chain, be sure to install it
properly not to have a slack; otherwise it may hit
wheel while driving.
4) When washing aluminum wheel, use neutral
synthetic detergent and water. Avoid using the
cleanser including abrasive, hard brushes or an
automatic car washer.
9. Wheel Balancing
1) Proper wheel balance may be lost if the tire is
repaired or if it wears. Check the tire for dynamic
balance, and repair as necessary.
2) To check for dynamic balance, use a dynamic
balancer. Drive in the balance weight on both the
top and rear sides of the rim.
3) Some types of balancer can cause damage to
the wheel. Use an appropriate balancer when
adjusting the wheel balance.
4) Use genuine balance weights.
CAUTION:
I55 g (1.94 oz) weight used with aluminum
wheel is not available.
IBalance weights are available for use with
any of 14- to 16-inch wheels.

5. Measure steering effort. Adjust or replace.
*1 If tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a condition, for example
before fluid warms-up, relief valve may work before maximum turning angle. In this case, steering effort may be heavy.
When measured hydraulic pressure is normal, there is no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After warming up engine,
turn steering wheel from stop to stop several times to warm up fluid. Then if steering effort reduces normally, there is no
abnormal thing.
*3 In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to excessive drop of idling
when turning steering wheel. In this case, it is recommended to start the vehicle with increasing engine speed than usual.
Then if steering effort reduces normally, there is no abnormal thing.

6) Slowly open the low-pressure manifold valve.
G4M0597
7) When the low-pressure gauge reaches approxi-
mately 66.43 kPa (498.3 mmHg, 19.62 inHg),
slowly open the high- pressure manifold valve.
8) Maintain a minimum vacuum level of 100.56
kPa (754.4 mmHg, 29.70 inHg) for a minimum of
15 minutes on a new system or 30 minutes for an
in-service system.
NOTE:
The gauge will read 4 kPa (25 mmHg, 1 inHg) less
for every 304.8 m (1,000 ft) above sea level.
G4M0598
B: PERFORM A VACUUM LEAK
TEST
1) After 15 minutes (or more) of evacuation, close
the high-pressure manifold valve.
2) Close the low-pressure manifold valve.
G4M0599
3) Turn off the vacuum pump.4) Note the low side gauge reading.
G4M0600
5) After 5 minutes, re-check the low-pressure
gauge reading.
If the vacuum level has changed more than 4 kPa
(25 mmHg, 1 inHg), perform an HFC-134a leak
test.
If the vacuum reading is about the same as noted
in step 4), continue on to next step.
6) Carefully attach the can tap to the refrigerant
can by following the can tap manufacturer's
instructions.
G4M0980
7) Disconnect the center manifold hose from the
vacuum pump and connect the hose to the tap
valve.
8) If a 13.6 kg (30 lb) container of refrigerant is
used a weight scale will be needed. This scale is
to determine the amount of refrigerant that is used.
Connect the center hose from the manifold to the
valve. Place the 13.6 kg (30 lb) container on the
scale, valve end down.
