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.
