- Conducting post-service/pre-delivery check: Includes reviewing systems, confirming components were installed/replaced correctly, and ensuring that the vehicle meets the specifications
- Learning Activities: Read objectives, review 'Information Sheets' (pages 2), complete 'Self-check 3' (page 71), and receive feedback from instructor on work quality.
Replace/Reassemble System Assemblies, Unit Three
-
Carrying out minor adjustments:
- Inspect cooling system hoses for leaks
- Check radiator for leaks and buildup of dirt/debris
- Verify coolant level (should be between low and full marks)
- Use correct coolant type
- Flush coolant system if it's contaminated
-
Coolant Condition:
- Use coolant hydrometer to check antifreeze percentage
- Check coolant color (should be green or orange, not rusty or cloudy)
-
Drive Belts:
- V-belts and V-ribbed belts used for various functions
- Drive belts wear over time and may cause slippage
- Inspection needed to check for damage: wear, glazing, tears, splits, or oil soaking
- Pulleys should be inspected for rust, oil, or damage and aligned properly
-
Belt Tension:
- Inspect belt tension regularly (midway through the largest span)
- Excessive belt tension issues can damage the associated components.
-
Using service information: Consult service manuals for correct belt tightening procedures and specifications.
Assembling System Components
- System Components: Connect the injector nozzle, cooling system, exhaust, and fuel pipes correctly.
- Thermostat: Connect fuel pipe and electrical lead.
- Additional Connections: Connect air filter, induction/exhaust manifold and cooling system properly.
Conducting Post-Service/Pre-Delivery Check
- Documentation: Use documentation to record organization's development & acquisition of operating environments & systems.
- Technician Access: Provide technicians with operation manuals for effective maintenance.
- Automated Documentation: Utilize software to improve maintainability & accuracy
Final Inspection
- Consumer Expectations: Consumers expect vehicles to be in excellent working order upon return.
- Inspection Criteria: Ensure that all safety components are correctly positioned and working properly and meets expected specifications.
- Documentation: Maintain records of all service work and any necessary repairs
Completing and Delivering Report/Final Procedures
- Report Delivery: Technicians deliver completed reports to the appropriate personnel.
- Documentation Procedures: Use standardized records, concise summaries, flow diagrams, and checklist items for maintenance and transparency.
