After cleaning the radiator, start the engine. Allow the
engine to operate at low idle speed for three to five
minutes. Accelerate the engine to high idle. This will
help in the removal of debris and the drying of the
core. Slowly reduce the engine speed to low idle and
then stop the engine. Use a light bulb behind the core
in order to inspect the core for cleanliness. Repeat
the cleaning, if necessary.
Inspect the fins for damage. Bent fins may be opened
with a “comb”. Inspect these items for good condition:
Welds, mounting brackets, air lines, connections,
clamps and seals. Make repairs, 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 correct operation. Check
the electrical connections and clean the electrical
connections. Refer to the Systems Operation, Testing
and Adjusting Manual, “Electric Starting System -
Test” for more information on the checking procedure
and for specifications consult your Perkins dealer or
your Perkins distributor for assistance.

Turbocharger - Inspect
A regular visual inspection of the turbocharger is
recommended. Any fumes from the crankcase 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.
If the turbocharger fails during engine operation,
damage to the turbocharger compressor wheel and/
or to the engine may occur. Damage to the
turbocharger compressor wheel can cause damage
to the pistons, the valves, and the cylinder head.
Refer to Systems Operation Testing and Adjusting,
Air Inlet and Exhaust System - Inspect and
Wastegate - Test for more information.

Walk-Around Inspection
Inspect the Engine for Leaks and
for Loose Connections
A walk-around inspection should only take a few
minutes. When the time is taken to perform these
checks, costly repairs and accidents can be avoided.
For maximum engine service life, make a thorough
inspection of the engine compartment before starting
the engine. Look for items such as fuel leaks, oil
leaks, coolant leaks, loose bolts, worn belts, loose
connections, and debris build-up. Make repairs, as
needed:
• The guards must be in the correct place. Repair
damaged guards or replace missing guards and
fixings.
• Wipe all caps and plugs before the engine is
serviced to reduce the chance of system
contamination.
NOTICE
For any type of leak (coolant, lube, or fuel) clean up
the fluid. If leaking is observed, find the source and
correct the leak. If leaking is suspected, check the flu-
id levels more often than recommended until the leak
is found or fixed, or until the suspicion of a leak is
proved to be unwarranted.
NOTICE
Accumulated grease and/or oil on an engine is a fire
hazard. Remove the accumulated grease and oil. Re-
fer to this Operation and Maintenance Manual, “En-
gine - Clean” for more information.
• Ensure that the cooling system hoses are correctly
clamped and that the cooling system hoses are
tight. Check for leaks. Check the condition of all
pipes.
• Inspect the water pump for coolant leaks.
Excessive coolant leakage may indicate the need to
replace the water pump. Remove the water pump.
Refer to Disassembly and Assembly, “Water Pump -
Remove and Install” for the correct procedure.
• Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters, and the rocker cover.
