Radiator Pressure Cap - Clean/
Replace
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
NOTICE
When any servicing or repair of the engine cooling
system is performed the procedure must be per-
formed with the engine on level ground. This will al-
low you to accurately check the coolant level. This
will also help in avoiding the risk of introducing an air
lock into the coolant system.
1. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly in
order to relieve any pressure. Remove the radiator
pressure cap.
2. Check coolant level. Refer to Operation and
Maintenance Manual, “Cooling System Coolant
Level - Check”.
3. Install new radiator pressure cap.

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 or consult your Perkins dealer
or your Perkins distributor for assistance.

Turbocharger - Inspect
SMCS Code: 1052-040
Hot engine components can cause injury from
burns. Before performing maintenance on the en-
gine, allow the engine and the components to
cool.
NOTICE
Turbocharger bearing failures can cause large quan-
tities of oil to enter the air intake and exhaust sys-
tems. Loss of engine lubricant can result in serious
engine damage.
Minor leakage of oil into a turbocharger under ex-
tended low idle operation should not cause problems
as long as a turbocharger bearing failure has not
occurred.
When a turbocharger bearing failure is accompanied
by a significant engine performance loss (exhaust
smoke or engine rpm up at no load), do not continue
engine operation until the turbocharger is renewed.
A visual inspection of the turbocharger can minimize
unscheduled downtime. A visual inspection of the
turbocharger can also reduce the chance for potential
damage to other engine parts. Do not inspect the
engine with the engine in operation.

Typical example
1. Ensure that the turbocharger is clean and free from
dirt before removing components for inspection.
