Changing coolant
1. To drain coolant, always open both drain cocks and
simultaneously open the radiator cap as well. With
the radiator cap kept closed, a complete drain of
water is impossible.
2. Remove the overflow pipe of the radiator pressure
cap to drain the recovery tank.
3. Prescribed coolant volume (U.S.gallons)
A
Coolant quantities shown are for standard radiators.
4. An improperly tightened radiator cap or a gap
between the cap and the seat quickens loss of
coolant.
5. Check and clean the plug threads and surface and
the pucking thims of the water drain plug to prevent
dirt and debris from the entering the engine.
6. Coolant (Radiator cleaner and anti-freeze)
ALL season: Pure water and anti-freeze (See "Anti-
freeze" in "RADIATOR" section.)
B
Remedies for quick decrease of coolant
1. Check any dust and dirt between the radiator fins
and tube. If any, remove them from the fins and the
tube.
2. Check the tightness of the fan belt. If loose, tighten it
securely.
3. Check the internal blockage in the radiator hose. If
scale forms in the hose, clean with the scale inhibitor
or its equivalent.
B
Checking radiator hoses and clamp
CAUTION
To avoid personal injury:
A
Be sure to check radiator hoses and
hose clamps periodically. If radiator
hose is damaged or coolant leaks,
overheats or severe burns could
occur.
Check to see if radiator hoses are properly fixed every
250 hours of operation or 6 months, whichever comes
first.
1. If hose clamps are loose or water leaks, tighten hose
clamp securely.
2. Replace hoses and tighten hose clamps securely, if
radiator hoses are swollen, hardened or cracked.
Replace hoses and hose clamps every 2 years or
earlier, if checked and found that hoses are swollen,
hardened or cracked.
B
Precaution at overheating
The event that the coolant temperature is nearly or more
than the boiling point is called
"OVERHEATING"
.
While running, make the following checks to see that all
parts are working correctly.
If anything is unusual,
inspect it, referring to the relevant description in
"MAINTENANCE" and "PERIODIC SERVICE"
section
.
C
Coolant
If the coolant temperature warning lamp lights up or if
steam or coolant does not stop squirting from the
radiator overflow pipe, turn off the load and
keep the
engine idling (COOLING-DOWN) for at least 5
minutes
to let it cool down gradually. Then stop the
engine and take the following inspection and servicing.
1. Check to see if the coolant runs short or if there is
any coolant leak;
2. Check to see if there is any obstacle around the
cooling air inlet or outlet;
3. Check to see if there is any dirt or dust between
radiator fins and tube;
4. Check to see if the fan belt is too loose; and
5. Check to see if radiator water pipe is clogged.
B
Cleaning radiator core (outside)
If dust is between the fin and tube, wash it away with
running water.
A
Do not clean radiator with firm tools such as spatulas
or screwdrivers. They may damage specified fin or
tube. It can cause coolant leaks or decrease cooling
performance.
