    IMIAL Level 1 Certificate in Vehicle Maintenance (QCF)
    IMIAL Level 1 Award in Vehicle Maintenance (QCF)
    IMIAL Level 1 Diploma in Vehicle Maintenance (QCF)

    Topic Overview

    The IMIAL Level 1 Certificate in Vehicle Maintenance (QCF) is an introductory qualification designed for learners who are new to the motor vehicle industry. It covers the fundamental principles of vehicle maintenance, including health and safety, tools and equipment, and basic servicing tasks. This qualification provides a solid foundation for further study or entry-level employment in a garage or workshop environment.

    Students will learn how to identify and use common hand tools, understand vehicle systems such as brakes, steering, and suspension, and perform routine maintenance like oil changes and tyre checks. The course emphasises safe working practices, including the correct use of lifting equipment and handling of hazardous materials. By the end of the certificate, learners will be able to carry out basic maintenance tasks under supervision.

    This qualification is part of the wider IMI Awards Ltd suite and aligns with industry standards. It is a stepping stone to the Level 2 Diploma in Vehicle Maintenance, which covers more complex repairs and diagnostics. Mastery of this certificate demonstrates to employers that you have the essential skills and knowledge to work safely and effectively in a motor vehicle environment.

    • Carry out the correct procedure for removing and refitting road wheels
    • Demonstrate safe lifting and supporting techniques when removing and refitting road wheels.
    • Identify the main components of a wheel and tyre assembly, including rim, bead, tread, and sidewall.
    • Explain the meaning of tyre sidewall markings, including size, load index, and speed rating.
    • Perform routine tyre pressure checks and adjust to manufacturer’s specifications.
    • Conduct a visual inspection of tyres for wear, damage, and legal tread depth.
    • Correctly mount and dismount a wheel using appropriate tools and torque settings.
    • Be able to work safely when working with road wheels and tyres, Know how wheel and tyres are constructed, Know wheel and tyre terminology, Be able to carryout routine maintenance and replacement of road wheels and tyres

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly identifying parts of the wheel and tyre assembly using technical terminology
    • Check that safety procedures are followed: chocking, jack positioning, axle stands, and PPE usage
    • Verify accurate use of a tyre pressure gauge and tread depth gauge against manufacturer or legal values
    • Assess correct torque application during wheel nut tightening and proper tightening sequence
    • Award credit for demonstrating correct use of personal protective equipment (PPE) and wheel chocks before starting work.
    • Expect learners to accurately read and interpret tyre sidewall information and relate to vehicle requirements.
    • Mark for following the correct torque sequence and final torque when refitting road wheels.
    • Checking for even tyre wear and correctly identifying causes such as under-inflation or misalignment.
    • Evidence of safely using a jack and axle stands, ensuring vehicle stability.
    • Award credit for consistently demonstrating correct selection and use of personal protective equipment (PPE), and adherence to safe lifting and supporting procedures (e.g., using axle stands and wheel chocks) throughout practical tasks.
    • Assess understanding of tyre construction by requiring accurate identification of components (tread, sidewall, bead, plies, belts) and explanation of their functions, including the difference between radial and cross-ply designs.
    • Evidence of competent routine maintenance must include precise tyre pressure checks against manufacturer specifications, tread depth measurements across the central three-quarters of the tread, and visual inspection for damage such as cuts, bulges, and uneven wear, with correct interpretation of sidewall markings (size, load index, speed rating, and date code).
    • For wheel removal and refitting, assess ability to follow correct tightening sequence, use calibrated torque tools to achieve specified torque values, and perform final safety checks (e.g., re-torque after road test) to prevent wheel detachment.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Memorise the layout of tyre sidewall markings and know what each code represents
    • 💡Follow a systematic routine during practical assessments: safety first, then inspection, then action
    • 💡Be prepared to explain the reasons behind each step, such as why wheels are tightened in a diagonal sequence
    • 💡Always reference the vehicle manufacturer’s specifications for tyre pressures and wheel torque settings in assessments.
    • 💡Practice the step-by-step procedure for wheel removal and refitting, verbalising each safety check.
    • 💡Memorise common tyre marking codes and be able to explain load index and speed rating without prompts.
    • 💡During practical assessments, double-check that the vehicle is stable on axle stands before removing wheels.
    • 💡Always reference the vehicle manufacturer’s data (handbook or specification chart) for torque settings and tyre pressures; this demonstrates professional practice and ensures safety margins.
    • 💡Verbalise each safety check before starting, such as verifying that the vehicle is securely supported, the handbrake is applied, and wheel chocks are in place—this makes your safe working practices explicit to the assessor.
    • 💡During practical assessments, perform a final ‘re-torque after 50 miles’ reminder and explain the importance of re-checking wheel fastenings to prevent loosening, showing your understanding of real-world service requirements.
    • 💡When inspecting tyres, systematically work from one sidewall to the tread to the other sidewall, this ensures you don’t miss any defects; also, note any cords or bulges that would render the tyre illegal.
    • 💡Always refer to the manufacturer's data or workshop manual for specific torque settings and fluid specifications. Examiners look for evidence that you can follow technical data accurately.
    • 💡When performing a practical task, explain what you are doing and why. This shows the examiner that you understand the underlying principles, not just the steps.
    • 💡Pay close attention to health and safety throughout the assessment. Even a minor oversight, like not wearing safety glasses, can cost you marks.

    Common Mistakes

    Common errors to avoid in your coursework

    • Confusing tyre aspect ratio with cross-section width when reading sidewall markings
    • Checking tyre pressures when tyres are hot, leading to inaccurate readings
    • Failing to use a calibrated torque wrench for final tightening of wheel nuts
    • Neglecting to recheck wheel nut torque after road test or vehicle settlement
    • Forgetting to loosen wheel nuts before raising the vehicle.
    • Misinterpreting tyre pressure units (psi, bar, kPa) and inflating to incorrect pressure.
    • Not resetting the tyre pressure monitoring system (TPMS) after tyre rotation or replacement.
    • Using impact wrenches without final torque wrench check, leading to over-tightening.
    • Confusing tyre pressure units (psi vs. bar) and misreading pressure gauges, leading to incorrect inflation.
    • Failing to check the spare wheel condition and pressure, assuming it is always roadworthy.
    • Using impact wrenches without torque-limiting extensions (torque sticks) and omitting to final-tighten with a torque wrench in the correct sequence.
    • Neglecting to inspect for uneven wear patterns that indicate suspension or alignment faults, treating only the symptom (tyre wear) instead of the cause.
    • Misinterpreting directional or asymmetric tread patterns, resulting in incorrect rotation or fitting.
    • Misconception: You can use any tool for any job. Correction: Always use the correct tool for the task to avoid damaging components or causing injury. For example, never use a socket wrench on a nut that requires a spanner.
    • Misconception: Jacking up a car is safe without axle stands. Correction: Never work under a vehicle supported only by a jack. Always use axle stands rated for the vehicle's weight to prevent crushing injuries.
    • Misconception: Brake fluid can be topped up with any fluid. Correction: Only use the brake fluid specified by the manufacturer (e.g., DOT 4). Mixing fluids can damage seals and cause brake failure.
