2. Loosen the cooling system filler cap slowly in
order to relieve any pressure. Remove the cooling
system filler cap.
Note: Drain the coolant into a suitable, clean
container. The coolant can be reused.
3. Drain the coolant from the cooling system to a
level that is below the hose that is being replaced.
4. Remove the hose clamps.
5. Disconnect the old hose.
6. Replace the old hose with a new hose.
7. Install the hose clamps.
8. Refill the cooling system.
9. Clean the cooling system filler cap. Inspect the
cooling system filler cap's gaskets. Replace
the cooling system filler cap if the gaskets are
damaged. Install the cooling system filler cap.
10. Start the engine. Inspect the cooling system for
leaks.

Radiator - Clean

The following text 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, dirt, 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 face 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 debris. 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 in a direction that is parallel with the tubes.
This will remove debris that is between the tubes.
Pressurized 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 order to soften mud. Clean the core from
both sides.
Use a degreaser 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 information regarding flushing the cooling system.
After cleaning the radiator, start the engine. This will
help in the 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 cleaning, if necessary.

Starting Motor - Inspect

Perkins recommends a scheduled inspection of the
starting motor. If the starting motor fails, the engine
may not start in an emergency situation.
Check the starting motor for proper operation. Check
the electrical connections and clean the electrical
connections. Refer to the Service Manual for more
information on the checking procedure and for
specifications or consult your Perkins distributors for
assistance.

Turbocharger - Inspect

Periodic inspection and cleaning are recommended
for the turbocharger compressor housing (inlet side).
Any fumes from the crankcase on the 1600D engine
are filtered through the air inlet system. Therefore,
by-products from oil and from combustion can collect
in the turbocharger compressor housing. Over time,
this buildup can contribute to loss of engine power,
increased black smoke and overall loss of engine
efficiency.
