temperature.
Should the oil level subsequently be topped-up, the level could
become too high, causing oil burning.
Typically, 0.875L is hung up.
Refill the engine with the correct specification engine oil.
58. Refill the automatic transmission. Refer to Section 307-01A,
Operation 44.24. 02.
59. Refill and bleed the power stee ring system. Refer to Section
211-02 General Procedures.
60. Repressurise the air conditioni ng system. Refer to Operation
82.30.30 and note all Wa rnings and Cautions.

ystem (pressure).
Outputs from the ECM control the radiator fans control module, located behind the left hand side of the bumper, to operate
the fans in the series mode (slow), paralle l mode (Fast) or Off modes. Hysteresis in the temperature and pressure switching
values prevents 'hun ting' between modes.
Under hot operating conditions, the fans may continue to operat e for some time after the engine has been switched off, but
will stop automatically when the coolant te mperature has been sufficiently reduced.
Engine Coolant Temperature Sensor (ECT) and ECM

The engine coolant temperature (ECT) sensor is located in the coolant outlet pipe and reacts to engine coolant temperature
changes, providing an input to the Engine Control Module (ECM). The sensor has a negative te mperature coefficient so that
the sensor resistance decrea ses as temperature rises.

The
automatic belt tensioner consists of an idler pulley which is
free to rotate on a bearing, located at the end of a spring-
loaded pivot arm.
The pivot arm can be turned counter-clockwise (viewed from th e front of the engine) for belt removal and installation.
A belt-wear indicator is incorporated on th e rear horizontal face of the pivot arm.
