Turbocharger – Overview
Turbocharger(s)
CAUTION: Do not switch off the engine
while it is running at high speed. If the
engine is switched off while it is running
at high speed, the turbocharger will
continue to run after the engine oil
pressure has already dropped to zero. This
will cause premature wear in the
turbocharger bearings.
A TC consists of an exhaust turbine located in the
exhaust gas flow, this turbine is connected to a
compressor by a shaft. The turbine is made to
rotate by the exhaust gas flow from the engine and
thus drives the compressor. The compressor
increases the pressure in the engine intake tract
so that a greater mass of air enters the cylinder
during the intake stroke.
The turbine housing of the TC is integrated into the
exhaust manifold. This construction offers
thermodynamic advantages compared with the
usual construction, the maximum exhaust
temperature is up to 1050°C.
The maximum boost pressure is 0.65 bar.
The exhaust manifold is secured to the exhaust
side of the cylinder head with 12 self-locking nuts.
The exhaust manifold gasket is a multi-layer steel
gasket and cannot be reused. In order to
compensate for the thermal expansion of the
exhaust manifold, the flange of the TC is provided
with two grooves.
The TC and the exhaust manifold are joined by a
hose clip. The hose clip must not be loosened or
removed. The TC and the exhaust manifold are
not available as separate replacement parts,
exchange is only possible as a complete unit.
The turbocharger heat shield is secured to the
exhaust manifold by four bolts. Two of the bolts
have spring washers underneath their heads.
During removal, make a note of the installation
location of the spring washers to refer to during
installation.
The recirculated air valve is built into the TC
housing and cannot be changed.
The Ford diagnostic unit can test the operation of
the wastegate control valve using actuator
diagnosis.
The boost pressure regulator is set in the factory.
Adjustments to the boost pressure regulator must never be attempted. A red colored seal is applied
to the adjustment nut of the operating rod, in order
to monitor the factory setting of the boost pressure.
The bearings of the TC are lubricated with engine
oil. The engine oil passes from the cylinder block
through the oil supply pipe to the TC. The oil is
returned to the oil pan through the oil return pipe,
The TC is cooled by the engine coolant circuit.
When installing hoses and lines, make certain that
their ends are free of oil residues and dirt.

Air Conditioning (A/C) Clutch Air Gap Adjustment
1.Check the gap A (measure the difference
between the engaged and disengaged positions
of the air conditioning clutch) at 60° intervals
around the circumference of the pulley. Operate
the air conditioning clutch several times with the
aid of a 5 A fused cable. Refer to the relevant
wiring diagram for the correct electrical
connection.
Refer to: Specifications (412-00 Climate Control
System - General Information, Specifications).
