Motor Vehicle Mechanics study plan
Motor Vehicle Mechanics · Give each week a clear focus.
8 weeks · About 6 hours per week
Motor Vehicle Mechanics
List the major systems of a motor vehicle (engine, transmission, brakes, steering, suspension, electrical) and describe the primary function of each in 2–3 sentences
Identify the location and basic operation of the four-stroke cycle components (pistons, valves, camshaft, crankshaft) using a labeled diagram you draw from memory
Define 15 core terms (torque, horsepower, compression ratio, clearance volume, valve timing, etc.) in a personal glossary with one example of each
Explain the difference between spark-ignition and compression-ignition engines in a short written comparison
Your checkpoint
A one-page handwritten or typed summary sheet listing each vehicle system, its function, and the four-stroke cycle in correct order, self-checked against a textbook index.
Motor Vehicle Mechanics
Describe the purpose and operation of the cooling system (radiator, thermostat, water pump) and list three common failure symptoms
Outline the lubrication system path from oil pan to bearings and explain the role of oil pressure and viscosity
Compare fuel delivery systems (port injection, direct injection, carburetor) in a table with advantages and disadvantages
Diagnose three hypothetical engine performance complaints (overheating, low oil pressure, rough idle) by listing likely causes in order of probability
Your checkpoint
A troubleshooting flow chart for one engine symptom (e.g., overheating) with at least five decision points and corresponding checks.
Motor Vehicle Mechanics
Explain how manual transmissions, automatic transmissions, and continuously variable transmissions transfer power, including the role of the clutch or torque converter
Trace the power flow from engine to drive wheels for a rear-wheel-drive and a front-wheel-drive layout
Identify the function of differentials, drive shafts, and CV joints and state one failure mode for each
Calculate final drive ratio and vehicle speed given tire size, gear ratio, and engine RPM using the standard formula
Your checkpoint
A solved problem set of five drivetrain calculations (gear ratios, speed, torque multiplication) with work shown and answers checked.
Motor Vehicle Mechanics
Describe the components and operation of hydraulic brake systems, including master cylinder, calipers, and proportioning valves
Explain the difference between disc and drum brakes and list inspection points for each
Outline the operation of ABS and traction control and state two symptoms of a faulty wheel speed sensor
Diagnose a spongy brake pedal and a pulling condition by listing at least four possible causes for each
Your checkpoint
A brake system diagram labeled with all major components and a written diagnostic checklist for three common brake complaints.
Motor Vehicle Mechanics
Identify the components of steering systems (rack-and-pinion, recirculating ball) and suspension systems (MacPherson strut, double wishbone, live axle)
Explain wheel alignment angles (camber, caster, toe) and describe the handling symptom associated with each being out of specification
Describe the function of shocks and struts and list three signs of worn dampers
Diagnose tire wear patterns (inner edge, outer edge, cupping) and match each to a likely alignment or suspension fault
Your checkpoint
A tire wear diagnosis chart with at least five wear patterns, the associated cause, and the recommended repair or adjustment.
Motor Vehicle Mechanics
Explain the purpose of the battery, starter, alternator, and charging circuit and describe how they interact during starting and running
Interpret basic electrical measurements (voltage, current, resistance) and apply Ohm's law to two simple circuit problems
Read a simplified wiring diagram and trace the circuit for a headlight and a starter relay
List the steps to diagnose a no-crank condition and a battery drain, including the use of a multimeter
Your checkpoint
A written diagnostic procedure for a no-crank complaint, with a numbered step sequence and expected voltage readings at each test point.
Motor Vehicle Mechanics
Integrate knowledge across systems by diagnosing three multi-system fault scenarios (e.g., overheating with electrical symptoms, vibration under braking)
Explain the purpose of onboard diagnostics (OBD-II) and how to retrieve and interpret a diagnostic trouble code
Describe the correct use of common hand tools and torque wrenches, including safety practices for lifting and supporting a vehicle
Outline a 30-minute vehicle inspection routine covering tires, brakes, fluids, lights, and belts
Your checkpoint
A completed 30-minute inspection checklist with pass/fail criteria for at least 15 items, plus a written diagnosis of one multi-system scenario.
Motor Vehicle Mechanics
Review weak areas identified from previous weeks using a personal error log and re-study the top three
Complete a timed 50-question practice test covering all systems and score at least 80%
Explain each incorrect answer from the practice test in writing, citing the correct principle
Summarize the ten most important safety and diagnostic principles in a one-page reference sheet
Your checkpoint
A scored practice test (80% or higher) with a written correction log for every missed question and a final one-page reference sheet.
Milestones
Week 2: Without notes, label a blank engine diagram with at least 12 components and correctly order the four-stroke cycle; self-score 80% or better.
Week 4: Explain the complete power flow from engine to wheels for both RWD and FWD layouts and solve three gear-ratio problems with correct answers.
Week 6: Diagnose three brake and suspension complaints from symptom to probable cause in under 10 minutes each, using the checklists you built.
Week 8: Score 80% or higher on the timed 50-question practice test and submit a correction log covering every missed item.
