Radiator - Clean
The following t
ext describes a typical cleaning
procedure for the radiator. For information on
equipment that is not supplied by Perkins, refer to
the OEM.
Note: Adjust the frequency of cleaning according to
the effects of
the operating environment.
Inspect the radiator for these items: damaged fins,
corrosion, d
irt, grease, insects, leaves, oil, and other
debris. Clean the radiator, if necessary.
Personal injury can result from air pressure.
Personal injury can result without following prop-
er procedure. When using pressure air, wear a pro-
tective fac
e shield and protective clothing.
Maximum air pressure at the nozzle must be less
than 205 kPa
(30 psi) for cleaning purposes.
Pressurized air is the preferred method for removing
loose debri
s. Direct the air in the opposite direction
of the fan’s air flow. Hold the nozzle approximately
6 mm (0.25 inch) away from the fins. Slowly move the
air nozzle i
n a direction that is parallel with the tubes.
This will remove debris that is between the tubes.
Pressuriz
ed water may also be used for cleaning.
The maximum water pressure for cleaning purposes
must be less than 275 kPa (40 psi). Use pressurized
water in or
der to soften mud. Clean the core from
both sides.
Useadegre
aser and steam for removal of oil and
grease. Clean both sides of the core. Wash the core
with detergent and hot water. Thoroughly rinse the
core with
clean water.
If the radiator is blocked internally, refer to the OEM
for infor
mation regarding flushing the cooling system.
After cleaning the radiator, start the engine. This will
help in t
he removal of debris and the drying of the
core. Run the engine for two minutes and then stop
the engine. Inspect the core for cleanliness. Repeat
the clea
ning, if necessary.

Severe Service Application -
Check
Severe service is the application of an engine that
exceeds the current published standards for that
engine. Perki
ns maintains standards for the following
engine parameters:
•
Performance
such as power range, speed range,
and fuel consumption
•
Fuel quality
•
Operational Altitude
•
Maintenance intervals
•
Oil selectio
n and maintenance
•
Coolant type and maintenance
•
Environmental qualities
•
Installatio
n
•
The temperature of the fluid in the engine
Refer to the standards for the engine or consult your
Perkins dealer or your Perkins distributor in order to
determine if
the engine is operating within the defined
parameters.
Severe serv
ice operation can accelerate component
wear. Engines that operate under severe conditions
may need more frequent maintenance intervals in
order to ens
ure maximum reliability and retention of
full service life.
Due to indiv
idual applications, it is not possible
to identify all of the factors which can contribute
to severe service operation. Consult your Perkins
dealer or y
our Perkins distributor for the unique
maintenance that is necessary for the engine.
The operat
ing environment, incorrect operating
procedures and incorrect maintenance procedures
can be factors which contribute to a severe service
applicat
ion.
