NAVTTC Auto Mechanic study guide
NAVTTC Auto Mechanic · Work through your exam, one topic at a time.
The NAVTTC Auto Mechanic credential sits within Pakistan's national technical and vocational training system, which NAVTTC describes as a competency-based system spanning eight NVQF levels, each defining the knowledge, skills and responsibility a learner demonstrates and the certification it leads to. Candidates are typically trainees enrolled through NAVTTC programmes such as the Prime Minister's Youth Skills Development Program, described as the national flagship program with 75,000+ trainees in the latest batch across 866 institutes, learning 103 demand-driven trades, or workers seeking formal recognition of existing hands-on experience through Recognition of Prior Learning, which NAVTTC presents as a route to an NVQF-recognised certificate without going back to class. The NAVTTC Auto Mechanic study guide has 7 sections and about 1,995 words.
01Engine systems diagnosis and repair
This domain tests how you confirm and correct faults in petrol and diesel engines: mechanical condition, timing, air intake, compression, ignition or combustion, and exhaust aftertreatment. The exam expects a diagnostic sequence, not parts swapping.
298 words, about 1 min02Transmission, drivetrain and clutch systems
This domain covers power transfer from engine to wheels: clutch operation, manual gearbox, driveshafts and CV joints, differential, and basic automatic transmission checks. The exam tests observation, measurement, and correct lubricant and assembly practice.
313 words, about 2 min03Braking systems and suspension
This domain tests hydraulic braking, friction components, ABS, and suspension support components. These are safety-critical systems: every repair ends with leak, pedal, and road tests.
280 words, about 1 min04Electrical and electronic systems
This domain covers battery, starting, charging, lighting, relays, sensors, and basic network diagnostics. The exam tests safe measurement and logical circuit testing.
279 words, about 1 min05Fuel, lubrication and cooling systems
This domain tests fuel delivery, air-fuel mixture, lubrication, and temperature control. It covers petrol injection, diesel common rail, oil specification, filters, coolant, thermostat, radiator, and fan operation.
290 words, about 1 min06Steering and wheel alignment
This domain tests steering geometry and tire wear diagnosis. The main angles are camber, caster, toe, and thrust angle; also included are steering linkage and power steering checks.
258 words, about 1 min07Workplace safety, tools and workshop practice
This domain tests safe workshop behavior and correct tool use: PPE, lifting, hand and power tools, measuring, torque, hazardous waste, and housekeeping. PPE: safety glasses, gloves, and steel-toe boots; eye protection is required for grinding, compressed air, and battery charging.
