System Operation
When the engine is running, the coolant is circulated around the engine cooling system by the coolant pump. From the coolant
pump, coolant flows through the cylinder heads and the engine oil cooler into the cylinder block and the heater manifold.

In the cylinder block, the coolant flows forwards to the outlet tube. When the coolant is cold, the thermostat is closed and the
coolant flows direct from the outlet tube back to the coolant pump. Once the coolant reaches operating temperature the
thermostat begins to open, to control system temperature, and coolant flows from the outlet tube to the coolant pump via the
radiator and, on SC (supercharger) vehicles, the auxiliary radiator. When the thermostat is open, the coolant flow through the
radiator(s) also generates a coolant flow through the transmission fluid cooler.

From the heater manifold the coolant flows through the electronic throttle and the heater core, in parallel circuits that are
unaffected by the position of the thermostat. From the electronic throttle, the coolant merges with bleed coolant from the
coolant pump and the outlet tube and flows to the expansion tank. From the heater core, the coolant flows back to the inlet of
the coolant pump.

Expansion and contraction of the coolant is accommodated by an air space in the expansion tank and the compliance of the
flexible hoses.

If the coolant level in the expansion tank decreases below a predetermined value, the level sensor connects a ground to the
instrument cluster, which activates the appropriate warning. For additional information, refer to 413-01 Instrument Cluster.

The cooling fan is operated by a fan control module integrated into the cooling fan motor. The fan control module regulates the
voltage, and thus speed, of the cooling fan motor in response to a PWM (pulse width modulation) signal from the ECM (engine
control module).

The cooling fan receives a battery feed and an ignition feed from the EJB (engine junction box). The ignition feed is supplied
from the main relay in the EJB, which is controlled by the ECM.
The ECM calculates the required fan speed from the engine temperature, A/C (air conditioning) system pressure and transmission fluid temperature. Under hot operating conditions, the fan may continue to operate for 4 minutes after the engine
has been switched off.



COOLANT PUMP Component Description



Item Description 1 Inlet connection 2 Pump body 3 Outlet flange to RH cylinder head 4 Outlet to engine oil cooler 5 Outlet flange to LH cylinder head

7 Bleed pipe connection (containing check valve) The body of the coolant pump contains an impeller attached to a shaft supported in a bearing assembly. The impeller is driven
by a pulley, pressed on to the front of the shaft, which is driven by the accessory drive belt. For additional information, refer to
303-05E Accessory Drive - 5.0L, Vehicles Without: Supercharger or 303-05F - 5.0L, Vehicles With: Supercharger.

Two coolant outlet flanges attach the coolant pump to the front of the cylinder heads. A pipe connects a further coolant outlet
to a pipe from the engine oil cooler. A bleed connector is installed in the front of the coolant pump, adjacent to the coolant
inlet connection from the thermostat. A check valve is incorporated into the bleed connection.

THERMOSTAT



Item Description 1 Screw (3 off) 2 Lower body 3 Upper body 4 Thermostat 5 Seal The thermostat is a multi-stage device located in the coolant pump inlet to provide fast response and control of the engine
outlet temperature.

The thermostat allows rapid engine warm-up by preventing coolant flow through the radiator and by limiting coolant flow
through the cylinder block when the engine is cold. During warm-up and at engines speeds above approximately 1800 rev/min,
a by-pass valve opens to control the coolant flow and pressure, to protect the engine components. When the thermostat
opening reaches 6 mm (0.24 in.), the by-pass flow is shut-off. When the thermostat opening exceeds 6 mm (0.24 in.), the
radiator coolant flow is further controlled up to the point where the thermostat is fully open. At this point maximum radiator
coolant flow is achieved to provide maximum cooling.

On both naturally aspirated and supercharger vehicles, the thermostat begins to open at 88 - 90 °C (190 - 194 °F) and is fully
open at 102 °C (216 °F).

WARNINGS: Published: 11-May-2011

Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


Before any work is carried out on the fuel system, ground the vehicle to earth and maintain the ground connection until
the work is complete.


CAUTION: Before disconnecting or removing components, make sure the area around the joint faces and connections are
clean. Plug open connections to prevent contamination.


NOTE: Tighten the fuel rail high pressure fuel pump fuel line unions and fuel rail crossover pipe unions as it is instructed
in service manual.

LOW AND HIGH PRESSURE FUEL LINES Component Description



Item Description A LP fuel lines B HP fuel lines 1 Acoustic cover 2 Heat reflective and insulation sleeves The LP fuel line connects the HP fuel pumps to the fuel delivery line from the fuel tank and lines system. A quick release
connector at the start of the LP fuel line is held in a clip integrated into the LH (left-hand) ignition coils cover. P-clips secure
the LP fuel line to the rear of each cylinder head and to the RH (right-hand) side of the cylinder block. A heat reflective and
insulation sleeves are installed on the LP fuel line where it runs behind the RH exhaust manifold.
The HP fuel lines connect the HP fuel pumps to the RH fuel rail and the crossover tube. Two P-clips and a pipe clamp attach the HP fuel lines to the cylinder block and the RH cylinder head respectively. An integral bracket on the front HP fuel line is attached to a stud on the front-upper RH timing cover. An acoustic cover is installed on the bottom of the front HP fuel line.
