9.9 Radiator

N O T E :
• Do not remove radiator filler cap until coolant
temperature is below its boiling point. Then loosen
cap slightly to the stop to relieve any excess
pressure before removing cap completely.
- Checking, Refiling and Changing Coolant
1.Remove the radiator pressure cap and check to
see that the coolant level is just below the port. If
l o w, add clean water.
Prescribed quantity
I M P O RTANT :
• Use clean, fresh water to fill the radiator.
• Securely tighten the radiator cap.
3. To drain the used coolant, open the radiator
drain cock and remove radiator cap. The radiator
cap must be removed to completely drain the
r a d i a t o r.
4. Be sure to close the pressure cap securely. If the
cap is loose or improperly closed, water may
leak out and the engine could overheat.
5. Radiator should be filled with part of anti-freeze
and water at all times as recommended by the
8.9L(9.4 u.s.qts.)
anti-freeze manufacturer. The anti-freeze contains
a corrosion inhibitor and will allow a higher
operating temperature in the radiator during the hot
s e a s o n .
6. Don't use an anti-freeze and scale inhibitor at the
same time.
- Checking Radiator Hose
Checking radiator hose tightness is prescribed
about every 150 service hours, but every 6 months
is all right so long as service duration does not
exceed 150 hours in 6 months.
1. If the tightener band is loose, apply a slight coat
of oil and securely retighten.
2. The radiator hose is made from rubber and
tends to age. It must be changed every two
years. Also change the tightener band and
securely tighten.
- Remedying Water Leakage
1. A small water leak can be eliminated with the
KIOTI Radiator Cement No. 40 or equivalent.
2. If water leakage should become excessive,
consult your local dealer.
- KIOTI Scale Inhibitor No. 11
1. The KIOTI Scale Inhibitor No. 11 prevents scale
formation in the cooling water. Scale which builds
up in either hard or soft water, sharply reduces
cooling eff i c i e n c y.
2.The Scale inhibitor is effective for 3 months so a
complete change of cooling water must be done
every 3 months.
- Cleaning Cooling System
1. The water cooling system should be cleaned on
the following occasions :
