FUEL INJECTOR
Removal
Caution: To reduce the risk of fire and personal injury, it is
necessary to relieve the fuel system pressure before
servicing the fuel system components.
Caution: After relieving the fuel system pressure, a small
amount of fuel may be released when servicing fuel lines
or connections. Reduce the chance of personal injury by
covering the fuel line fitting with a shop towel before
disconnecting the fittings. The towel will absorb any fuel
that may leak out. When the disconnect is completed,
place the towel in an approved container.
1. Depressurize the fuel system.
2. Disconnect the fuel inlet.
3. Disconnect the fuel return line.
4. Remove the fuel rail from the intake manifold.
5. Remove the fuel injector from the fuel rail by disengaging
claws.
Installation
1. Install the fuel injector to the fuel rail by engaging claws.
2. Install the fuel rail to the intake manifold.
3. Connect the fuel return line firmly.
4. Connect the fuel supply line firmly.

Engine Oil Viscosity
The following engine oils can be used:
A = single-grade oils
B = multigrade oils
C = easy run oils
depending on the outside temperature.
Engine Oil Quality
It is important that the following API and CCMC classes are
used:
Engines Single and multigrade oils Easy run oils
Petrol API-SF/CC, SF/CD, SG/CC,
SG/CD, CCMC/G4 API-SF/CC, SF/CD, SG/CD
CCMC-G5/PD2
Important!
CD engine oils designed by manufacturers specially for diesel
engines are not suitable for petrol engines, unless a sufficient
performance class for petrol engines (e.g. API-SF/CCMC-G4)
is also indicated.
