Note
1. Notes that are necessary for steering system:
(a) It is necessary to change parts correctly, for they will influence the performance of steering system to
make running danger.
2. Notes that are necessary for SRS airbag:
(a) MR7180 assembles with SRS (auxiliary protection system) such as safety airbag at the side of driver
and safety airbag at the side of passenger.
Maintenance does not accord with correct repair step, this might incur SRS explodes suddenly in
repair term to make heavy accident. Before repairing auxiliary protection system (including
disassembling, assembling, check or change parts), it is necessary to read the notes in SRS chapter
(auxiliary protection system).

Power steering--Poser steering system
Inspection on automobile
1. Check driving belt
(a) Check whether the belt has been abraded too much with eyes, and rope is broken.
If finding any defect, change the driving belt.
Hint: Some light crack at the side of belt rib could be approved, but if belt has any crack from
its rib, it is necessary to change.
2. Exhaust air of power steering system
(a) Check the oil level.
(b) Lift up automobile body, and support it with bracket.
(c) Turn steering wheel.
(1) Turn steering wheel slowly from left and right to bottom for several times when engine extinguishes.
(d) Lay down the automobile.
(e) Start the engine to make it run at idling speed for several minutes.
(f) Rotate steering wheel.
(1) Keep engine at idling speed, and turn the steering wheel from left or right to bottom and keep this
state for 2-3 seconds, then turn it to the other direction for 2-3 seconds.
(2) Repeat (1) for several times.
(g) Engine extinguishes.
(h) Check whether there is any foam or emulsification
phenomenon.
If there is any foam or emulsification phenomenon and
it is necessary to exhaust air second time, it is necessary
to check whether the system has any leakage.
(i) Check the oil level.
3. Check the oil level
(a) Keep automobile horizontal.
(b) Extinguish the engine, and check the oil level of oil stor-
age tank.
If oil level is too low, add oil.
Power steering oil: automatic transmission oil
DEXRON’’ II or III
Hint: check whether the oil level is in the HOT mark
scope of oil storage tank, if oil is cool, check the
oil level is in COLD mark scope.
(c) Start the engine, and keep it at idling speed.
(d) Turn steering wheel from left bottom to right bottom for
several times to make oil temperature increase.
Oil temperature: 80°C

(a) Insure steering gear hole is not plugged by lubricating
grease.
Hint: if hole is plugged, the pressure in dust-proof
cover when steering wheel turns after combin-
ing will change.
(b) Assemble dust-proof cover, fixed clamp and new iron wire.
Note: do no t hurt or bend dust-proof cover.
(c) After coiling dust-proof cover with iron wire for two circles,
turn it for several circles to fix it.
(d) Liking that shown in figure, bend iron wire to rotating di-
rection to prevent it from hurting dust-proof cover.
Hint: assemble the other side with same method.
30. Assemble No.1 dust-proof cover of steering gear.
31. Assemble left ball head of transversal lever .
(a) Screw locking cap and transversal lever ball head in gear
terminal lever until aligning the mark.

Note
1. Do not dispose Refrigerant in sealed space or near
flame.
2. Wear glasses to protect your eyes.
3. Do not let liquid Refrigerant contact with your eyes
or skin.
If liquid Refrigerant contacts with your eyes or skin:
(a) Wash the contacted part with much water.
Warning: do not knead your eyes or skin.
(b) Spread clean Vaseline on your skin.
(c) Go to doctor or hospital for special cure.
4. Forbid heating it or making it expose the flame.
5. Forbid dropping the Refrigerant tank or shake it
intensively.
6. Do not operate compressor when Refrigerant is lack.
If the Refrigerant in cooling system is lack, it will incur com-
pressor burned out for lacking lubrication. So it is necessary
to avoid.
7. Do not open the high pressure valve of filling instru-
ment package when compressor is working.
If opening the valve at this time, Refrigerant will flow back into
refrigerant tank to incur the tank will break. So only the low
pressure valve could be opened or closed.
8. Do not fill Refrigerant too much.
Too much refrigerant will make many problems such as lack
cooling degree, oil consumption, too hot engine and so on.
Inspection on automobile
1. Check the No.1 pressure switch.
(a) Control for electromagnetic clutch:
Check the function of pressure switch.
(1) Assembly filling instrument package.
(2) Connect the anode lead of OUM meter to No. 4 termi-
nal and connect cathode lead to No. 1 terminal.
(3) Liking that shown in figure. When refrigerant pressure
is changed, check the conduction between terminals.

1. Reclaim HFC-134a (R134a)
(a) Turn A/C switch to ON.
(b) Keep the engine speed at 1000 rpm, and rotate cooling compressor for 5 to 6 minutes to make
refrigerant cycle, this could collect the Refrigerant oil in each part in cooling compressor as possible.
(c) Extinguish the engine.
(d) Drain the refrigerant.
2. Fill refrigerant
(a) Use vacuum pump to take out vacuum.
(b) Fill the refrigerant HFC-134a (R134a)
Standard quantity: 660 ± 10g
3. Heat the engine
4. Check whether the refrigerant leaks.
