Skills in Maintaining Automotive Engine and Chassis Components
This subtopic focuses on developing practical skills for maintaining engine and chassis systems, including adhering to health and safety protocols, correctly using tools and technical information, and competently removing, inspecting, and replacing components. It also emphasizes the importance of accurate record-keeping and making informed recommendations based on inspection findings.
Assessment criteria
Topic Overview
The IMI Level 2 Certificate in Automotive Maintenance provides foundational knowledge and practical skills for servicing and repairing light vehicles. It covers key systems such as engines, transmissions, brakes, steering, suspension, and electrical systems, preparing students for entry-level roles in the automotive industry. This qualification is essential for understanding how modern vehicles operate and how to maintain them safely and efficiently.
Students learn to use diagnostic tools, interpret technical data, and perform routine maintenance tasks like oil changes, brake inspections, and tyre rotations. The course emphasizes health and safety regulations, including the safe use of workshop equipment and proper disposal of hazardous materials. By mastering these skills, students build confidence to progress to advanced qualifications or apprenticeships in motor vehicle maintenance and repair.
This certificate is recognized by employers across the UK automotive sector, from independent garages to franchised dealerships. It aligns with industry standards set by the Institute of the Motor Industry (IMI), ensuring that graduates meet the demands of a rapidly evolving field, including the growing integration of hybrid and electric vehicle technologies.
Key Concepts
Core ideas you must understand for this topic
- →Vehicle systems: Understand the function and interaction of engine, transmission, braking, steering, suspension, and electrical systems.
- →Maintenance procedures: Perform routine tasks like fluid level checks, filter replacements, and brake pad inspections following manufacturer specifications.
- →Diagnostic techniques: Use multimeters, scan tools, and visual inspections to identify faults in mechanical and electrical systems.
- →Health and safety: Apply COSHH regulations, use personal protective equipment (PPE), and follow safe lifting and jacking procedures.
- →Tools and equipment: Select and use hand tools, power tools, and specialist equipment (e.g., tyre changers, brake lathes) correctly.
Learning Objectives
What you need to know and understand
- 1. Be able to follow health and safety practices within an automotive environment 2. Be able to use tools, equipment and information when maintaining engine and chassis system components 3. Be able to remove, inspect and replace engine and chassis system components4. Be able to record information and make suitable recommendations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct selection and use of personal protective equipment (PPE) and following safe isolation procedures before starting work.
- Evidence of systematic inspection using manufacturer specifications, with clear recording of measurements against tolerances.
- Ability to interpret workshop manuals and technical data to guide component removal and replacement.
- Producing a legible, detailed job card that includes findings and justified recommendations for further action.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the vehicle manufacturer's service schedule and technical data during practical assessments to validate your methods.
- 💡When recording information, use precise terminology and measurements rather than vague descriptions like 'a bit loose'.
- 💡Before submitting work, double-check that all removed components have been refitted using correct torque settings and that no tools are left in the engine bay.
- 💡Always refer to manufacturer data when answering questions about service intervals or torque settings – examiners look for evidence of using technical information correctly.
- 💡In practical assessments, demonstrate safe working practices consistently, such as isolating the battery before electrical work and using axle stands when the vehicle is raised.
- 💡When explaining faults, use a systematic approach: describe the symptom, possible causes, diagnostic steps, and the corrective action. This structure earns full marks.
Common Mistakes
Common errors to avoid in your coursework
- Failing to disconnect the battery before working on engine electrical components, risking short circuits.
- Using an impact wrench to tighten critical fasteners without final torque verification, leading to under/over-torqueing.
- Neglecting to check fluid levels or condition before road testing after repairs.
- Overlooking the importance of recording minor observations on the job card, which could indicate emerging faults.
- Misconception: All maintenance tasks are the same for every vehicle. Correction: Each vehicle has specific service intervals and procedures outlined in the manufacturer's handbook; using generic methods can lead to damage or safety risks.
- Misconception: Diagnostic trouble codes (DTCs) always pinpoint the exact fault. Correction: DTCs indicate a symptom area; further testing (e.g., voltage checks, component testing) is needed to confirm the root cause.
- Misconception: Brake fluid never needs changing. Correction: Brake fluid is hygroscopic and absorbs moisture over time, reducing its boiling point and braking efficiency; it should be replaced per the manufacturer's schedule.
