Cooling System (03.03)
Description
The water pump is of a conventional design and is located at
the front of the engine. It is driven by the accessory drive
belt.
Thermostat
The thermostat allows rapid en gine warm-up by redirecting
coolant flow through the engine below 88 °C (190.5°F).
The thermostat also assists in keeping the engine operating
temperature within predetermi ned limits. The thermostat
starts to open between 86°C - 90°C (186.8°F - 194°F) and is
fully open at 102°C (215.5°F).
Cold Engine (Bypass Circuit) - When the engine is cold and
the thermostat is closed coolant flows from the water pump
through the engine block, through the cylinder heads and
into the water cross-over housing. Coolant then passes
through the secondary thermostat sealing plate and returns
to the water pump.
Warm Engine (Cooling Module Circuit) - When the engine
is warm and the thermostat is open coolant flows from the
water pump, through the engine block, through the cylinder
head and into the water cros s-over housing. Coolant then
passes through the upper coolant hose, through the radiator and returns to the water pump through the lower coolant
hose and water cross-over housing.
Radiator
The radiator is of aluminium construction with plastic end
tanks. Foam seals are installed to the radiator to prevent the
cooling air from by-passing the radiator core. The radiator is
located by four isolator mo
untings and supported by the
radiator support beams. A coolant drain plug is provided in
the lower right-hand side for the draining of the coolant. The
cooling fan shroud is attached to the radiator.
Cooling Fans
Two variable speed electric cooling fans are housed in the
cooling fan pack for the cooling of the radiator. The speed of
the electric cooling fans is adjusted by the Powertrain
Control Module (PCM).
Coolant Reservoir
A pressurised coolant reservoir system is used which
continuously removes any air from the cooling system. A
continuous vent from the engine and radiator to the coolant
expansion tank prevents air locks from forming in the

cooling system. No manual bleed points are provided on the
system.
The coolant reservoir should be full when the coolant system
is cold.
Engine Oil Cooler
The oil temperature is contro lled by an air/oil cooler
mounted at the front of the car. Engine oil is removed from
the dry sump, with the scavenge pump. The oil is routed to
a temperature controlled thermostat which controls the
directional flow of the oil. With the thermostat closed the oil
is routed directly to the oil tank. When the thermostat starts
to open (at 105°C) the oil is routed via the air/oil cooler
before entering the tank.

Major Components
Compressor
• Engine mounted, driven by the accessory drive belt
• Variable displacement type
• High-pressure relief valve, to avoid system over-pressure
• ECU controlled clutch energised via a relay
Receiver drier
• Vertically mounted on the right-hand side of the engine bay
• The high-side charge port is installed to the high side entry pipe to the receiver drier
Condenser
• Multi-pass fin-over-tube type, mounted in front of the engine cooling pack and directly to the radiator
Trinary switch
Located in the compressor discharge pipe
• Provides a signal, via the A/C module, to the PCM, to disengage the compressor clutch should the refrigerant
pressure be less than 2 bar or greater than 30 bar
• Provides a hard-wired signal to the PCM, to switch the cooling fans to HIGH speed at 22 bar rising pressure and
to LOW speed at 17,5 bar falling pressure
• Provides a hard-wired signal to the PCM, to switch the radiator cooling fans to LOW speed at 12 bar rising
pressure and to switch the fans OFF at 8 bar falling
pressure
Expansion Valve
The expansion valve is located on the outside of the A/C unit
and comprises of a diaphragm, connected by a capillary
tube to a temperature sensing bulb, which regulates the
valve according to temperature variations at the evaporator
outlet pipe. This component is not serviceable.
