CAUTION:

• Always replace exhaust gasketswithnewones when reas-

shown atleft.
• With engine running, checkalltube connections forexhaust
gas leaks, andentire system forunusual noises.
• After installation, checktoensure thatmounting brackets
and mounting insulators arefree from undue stress.
If
any
of the above partsarenotinstalled properly, excessive

Mass AirFlow Sensor (MAFS)

The mass airflow sensor measures theintake airflow rateby
taking apart ofthe entire flow.Measurements aremade insuch
a manner thattheECM receives electrical outputsignals var-
ied bythe amount ofheat emitting fromthehotwire placed in
the stream ofthe intake air.
When intake airflows intotheintake manifold througharoute
around thehotwire, theheat generated fromthehotwire is
taken awaybythe air.The amount ofheat depends onthe air
flow. Onthe other hand, thetemperature ofthe ..hot wire is

SEF154N
automatically controlledtoacertain number ofdegrees.
Therefore, itis necessary tosupply thehotwire withmore •
electric currentinorder tomaintain thetemperature ofthe hot
wire. TheECM knows theairflow bymeans ofthe electric
c~ange.

AirFlow Sensor (MAFS)

The mass airflow sensor isplaced inthe stream ofintake air.
It measures theintake flowratebymeasuring apart ofthe
entire intake flow.Itconsists ofahot wire thatissupplied with
electric currentfromtheECM. Thetemperature ofthe hotwire
is controlled bythe ECM acertain amount. Theheat generated
by the hotwire isreduced asthe intake airflows around it.The
more air,thegreater theheat loss.
Therefore, theECM mustsupply moreelectric currenttomain-
tain thetemperature ofthe hotwire asair flow increases. The

should beslackened againsttheengine.
e. Before disconnecting fuelhose, release fuelpressure from
fuel line.
Refer to"Releasing FuelPressure" inEC section.
f. Besure tohoist engine andtransaxle inasafe manner.
g. For engines notequipped withengine slingers, attach
proper slingers andbolts described inPARTS CATALOG.
CAUTION:
• When liftingengine, besure toclear surrounding parts.
Take special careforaccelerator wirecasing, brakelines
and brake master cylinder.
• Inhoisting theengine, alwaysuseengine slingers inasafe
manner.
• Inremoving driveshaft, becareful nottodamage grease
seal oftransaxle.
Engine cannotberemoved separately fromtransaxle. Remove
engine withtransaxle.

General Precautions (Cont'd)

• Before jacking upthe vehicle, applywheel chocks orother
tire blocks tothe wheels toprevent thevehicle frommov-
ing. After jacking upthe vehicle, supportthevehicle weight
with safety stands atthe points designated forproper lifting
before working onthe vehicle.
These operations shouldbedone onalevel surface.
• When removing aheavy component suchasthe engine or
transaxle/transmission, becareful nottolose your balance
and drop them. Also,donot allow themtostrike adjacent
parts, especially thebrake tubesandmaster cylinder.
• Before starting repairswhichdonot require batterypower:
Turn offignition switch.
Disconnect thenegative batteryterminal.
• Toprevent seriousburns:
Avoid contact withhotmetal parts.
Do not remove theradiator capwhen theengine ishot.
• Before servicing thevehicle:
Protect fenders, upholstery andcarpeting withappropriate
covers.
Take caution thatkeys, buckles orbuttons donot scratch
paint.
• Clean alldisassembled partsinthe designated liquidor
solvent priortoinspection orassembly.
• Replace oilseals, gaskets, packings, O-rings,locking
washers, cotterpins,self-locking nuts,etc.with newones.
• Replace innerandouter races oftapered rollerbearings
and needle bearings asaset.
• Arrange thedisassembled partsinaccordance withtheir
assembled locationsandsequence.
• Donot touch theterminals ofelectrical components which
use microcomputers (suchasECMs).
Static electricity maydamage internalelectronic compo-
nents.

•Using theholder toprevent driveplaterotation, tightenthe
bolt to12to15 N'm (1.2to1.5 kg-m, 9to 11ft-Ib) torque.

After tightening thebolt, check thatthepulley rotates smoothly.

• Check clearance aroundtheentire periphery ofclutch disc.

Disc-to-pulley clearance:
0.3 -0.6 mm (0.012 -0.024 in)

If the specified clearance isnot obtained, replaceadjusting
spacer andreadjust.

BREAK-IN OPERATION

When replacing compressor clutchassembly, alwaysconduct •
the break-in operation. Thisisdone byengaging anddisengag-
i

ing the clutch aboutthirtytimes. Break-in operation raisesthe
