Engine Cooling System Engine
Radiator and Cooling Fan
The radiator is a cross flow type with an aluminium matrix
with moulded plastic end tanks and, if fitted, an automatic
transmission oil cooler. The radiator has features that carry
the fan assembly and Air Conditioning ( A/C ) condenser and
intercooler (Turbocharger). The lower section of the radiator
is located in rubber bushes supported by brackets fitted to the
front longitudinals. The top of the radiator is located in rubber
bushes in the bonnet locking platform. A plastic shroud is fitted
behind the front bumper to direct air through the radiator.
The condenser is installed in front of the radiator and locates
on two lower mounting lugs secured to the radiator with two
bolts. The turbocharger intercooler is mounted in front of the
lower section of the radiator.
The radiator cooling fan and motor assembly is fitted to a cowl
at the rear of the radiator. A heatshield is fitted to the rear of
the motor to protect it from the high temperature generated
by the turbocharger. The fan is a 'pull through' type drawing air
through the radiator when in operation with the cowl featuring
five additional vents on the LH side to allow for increased air
flow across the radiator during high speed driving. The cooling
fan relay unit is fitted to the LH side of the radiator.
Engine Coolant Temperature (ECT)Sensor
The ECT sensor is fitted into the coolant elbow and consists
of an encapsulated Negative Temperature Coefficient ( NTC )
thermistor which is in contact with the engine coolant and is
part of a voltage divider circuit which consists of a regulated
5 volt supply, a fixed resistor inside the Engine Control
Module ( ECM ) and a temperature dependent variable resistor
(the ECT sensor).
