System Pressure Release

Coolant System

Pressurized system: Hot coolant can cause seri-
ous burn. To open cap, stop engine, wait until ra-
diator is cool. Then loosen cap slowly to relieve
the pressure.
The engine can have the ability to auto start. Ensure
that the power supply is isolated before any service
or repair is performed.
To relieve the pressure from the coolant system, turn
off the engine. Allow the cooling system pressure cap
to cool. Remove the cooling system pressure cap
slowly in order to relieve pressure.

Fuel System

To relieve the pressure from the fuel system, turn off
the engine.
High Pressure Line for Fuel Injectors
The high-pressure line is between the high-pressure
pump and the high-pressure manifold within the
cylinder head. The line is different from pressure
lines on other systems.
The high-pressure line is different for the following
reasons:
•
The high-pressure line is constantly charged with
high-pressure fluid.
•
The internal pressures of the high-pressure lines
are higher than other types of system.
Before any service or repair is performed on the
engine lines, perform the following tasks:
1. Stop the engine.
2. Wait for 10 minutes.
Do not loosen the high-pressure line in order to
remove air from the system.

Engine Oil

To relieve pressure from the lubricating system, turn
off the engine.

Welding on Engines with
Electronic Controls
Because the strength of the frame may decrease,
some manufacturers do not recommend welding
onto a chassis frame or rail. Consult the OEM of the
equipment or your Perkins dealer regarding welding
on a chassis frame or rail.
Proper welding procedures are necessary in order
to avoid damage to the engines ECM, sensors, and
associated components. When possible, remove
the component from the unit and then weld the
component. If removal of the component is not
possible, the following procedure must be followed
when you weld on a unit equipped with an Electronic
Engine. The following procedure is considered to be
the safest procedure to weld on a component. This
procedure should provide a minimum risk of damage
to electronic components.
Do not ground the welder to electrical components
such as the ECM or sensors. Improper grounding can
cause damage to the drive train bearings, hydraulic
components, electrical components, and other com-
ponents.
Clamp the ground cable from the welder to the com-
ponent that will be welded. Place the clamp as close
as possible to the weld. This will help reduce the pos-
sibility of damage.
Note: Perform the welding in areas that are free from
explosive hazards.
1. Stop the engine. Turn the switched power to the
OFF position.
2. Ensure that the fuel supply to the engine is turned
off.
3. Disconnect the negative battery cable from the
battery. If a battery disconnect switch is provided,
open the switch.
4. Disconnect all electronic components from
the wiring harnesses. Include the following
components:
