1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug (1) to drain coolant.
3) Remove reservoir and drain.
4) Tighten plug securely. Also reinstall reservoir.
5) Fill radiator with specified amount of coolant, and run engine
for 2 or 3 minutes at idle. This drives out any air which may
still be trapped within cooling system. STOP ENGINE.
Add coolant as necessary until coolant level reaches the
filler throat of radiator. Reinstall radiator cap.
6) Add coolant to reservoir so that its level aligns with Full
mark. Then, reinstall cap aligning arrow marks on reservoir
and cap. CAUTION:
When changing engine coolant, use mixture of 50% water
and 50% ANTIFREEZE/ANTICORROSION COOLANT for
the market where ambient temperature falls lower than –
16°C (3°F) in winter, and mixture of 70% water and 30%
ANTIFREEZE/ANTICORROSION COOLANT for the market
where ambient temperature doesn’t fall lower than –16°C
(3°F).
Even in a market where no freezing temperature is antici-
pated, mixture of 70% water and 30% ANTIFREEZE/ANTI-
CORROSION COOLANT should be used for the purpose
of corrosion protection and lubrication.

ABNORMAL NOISE DIAGNOSIS
There are various types of noise, ranging from those produced in the engine compartment to those from the
passenger compartment, also from rumbling noises to whistling noises.
ABNORMAL NOISE FROM COMPRESSOR
ABNORMAL NOISE FROM MAGNETIC CLUTCH
ABNORMAL NOISE FROM TUBING
ABNORMAL NOISE FROM CONDENSER
Condition Possible Cause Correction
During compressor
operation, a rumbling
noise is heard propor-
tional to engine
revolutions.Inadequate clearance in piston area (piston or
swash-plate)Repair or replace compressor as
necessary.
A loud noise is heard
at a certain rpm, dis-
proportionately to
engine revolution.Loose or faulty compressor drive belt Adjust drive belt tension, or replace
drive belt.
Loose compressor mounting bolts Retighten mounting bolts.
A loud rattle is heard
at low engine rpm.Loose compressor clutch plate bolt Retighten clutch plate bolt.
Replace compressor if it was oper-
ated in this condition for a long
time.
Condition Possible Cause Correction
A rumbling noise is
heard when compres-
sor is not operating.Worn or damaged bearings Replace magnet clutch assembly.
A chattering noise is
heard when compres-
sor is engaged.Faulty clutch clearance (excessive) Adjust clutch clearance.
Worn clutch friction surface Replace magnet clutch assembly.
Compressor oil leaked from lip type seal, con-
taminating the friction surfaceReplace compressor body assem-
bly.
Condition Possible Cause Correction
