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

Item Description 1 Filler cap 2 Vent hose connection 3 Expansion hose connection 4 Level sensor The expansion tank is installed in the engine compartment, on the LH upper suspension housing.
A filler cap and level sensor are incorporated into the expansion tank. A MAX level marking is molded into the interior of the
tank below the filler cap. Cold fill levels are molded onto the exterior of the tank.
The expansion tank provides the following functions:
Service fill.
Coolant expansion during warm-up.
Air separation during operation.
System pressurization by the filler cap.

The expansion tank has an air space of approximately 0.5 liter (1.06 US pints), above the MAX level, to allow for coolant
expansion. EXPANSION TANK

ENGINE COOLANT

The engine coolant is formulated to last for ten years or 240,000 km (150,000 miles). The coolant is silicate free and must not
be mixed with conventional engine coolant.

ENGINE BLOCK HEATER



Item Description A 110 V ac version B 240 V ac version For vehicle markets subject to very cold climatic conditions, an engine block heater is installed in place of the cylinder block
drain plug. The engine block heater is either a 110 V ac or 240 V ac electric heater element, depending on the market, which
can be connected to a domestic power supply via a connector in the lower center grill of the front bumper. Heater Manifold

Principle of Operation

For a detailed description of the engine cooling system and operation, refer to the relevant description and operation section of
the workshop manual. Engine Cooling, Section - 303-03

Inspection and Verification


WARNING: Moving parts can cause severe injury, keep clear of moving parts, never place your hands or any part of your
body near to moving parts


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle
NOTES:


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

1. Verify the customer concern

2. Visually inspect for obvious signs of mechanical or electrical damage
