Application
This unit describes the performance outcomes required to inspect and service air and liquid cooling systems. It involves preparing for the task, inspecting the system, reporting the inspection findings, servicing and adjusting the system, reporting the inspection findings, and completing workplace processes and documentation.
It applies to those working in the automotive service and repair industry. The cooling systems include those of agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, mobile plant machinery, motorcycle or outdoor power equipment.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the cooling systems that they have worked on, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
manufacturer cooling system specifications
two different vehicles or machinery with cooling systems requiring servicing
cooling system test equipment
tools, equipment and materials appropriate for inspecting and servicing cooling systems.
