Automotive Servicing NC II study plan

Memorize the 5S housekeeping sequence and demonstrate it by organizing a simulated workbench layout on paper with labeled tool positions

List the personal protective equipment required for engine work (gloves, goggles, safety shoes, hearing protection) and match each item to the specific hazard it controls

Trace the four-stroke cycle (intake, compression, power, exhaust) and label valve position and piston direction for each stroke on a hand-drawn diagram

Identify the main engine mechanical components (cylinder head, block, pistons, rings, connecting rods, crankshaft, camshaft, timing belt/chain) and state one function and one common failure mode for each

Describe the cooling system flow path from water pump through block, head, thermostat, radiator, and back, and explain the role of the pressure cap and coolant expansion

Diagnose three written cooling-system scenarios (overheating at idle, coolant loss with no visible leak, heater blowing cold) and state the first two tests you would run for each

Demonstrate correct use of a micrometer and vernier caliper by recording readings from practice measurements and converting them to the nearest 0.01 mm

Explain how to perform a cylinder compression test and a cooling system pressure test, including engine temperature, throttle position, and pass/fail interpretation

Map the lubrication circuit from oil pan through pickup, pump, filter, galleries, and drain-back, and explain what happens when the pressure relief valve sticks

Compare the properties and service intervals of conventional, semi-synthetic, and full-synthetic engine oil using the viscosity grade and API/ILSAC service category

Trace the fuel delivery path for both carbureted and electronic fuel injection systems and distinguish the function of pump, filter, regulator, injector, and return line

Perform valve clearance measurement and adjustment procedures on paper for a specified engine, listing the tools, feeler gauge steps, and torque values needed

Interpret a written oil-pressure complaint (gauge low at idle, normal at speed) and list five possible causes ranked by likelihood

Explain the charging system circuit from battery through alternator, voltage regulator, and warning lamp, and state the expected charging voltage range at idle and at 2,000 rpm

Describe how to test a battery with a hydrometer and a load tester, and interpret state-of-charge and cold-cranking-amp results

Diagnose a no-crank condition by ordering the checks from battery terminals through ignition switch, starter relay, and starter solenoid

Trace a headlight and turn-signal circuit including fuse, switch, relay, and ground, and explain how to locate an open circuit with a test light or multimeter

State the safety precautions for handling batteries and alternators, including hydrogen gas, acid, and disconnecting the negative terminal first

Identify the components of drum and disc brake systems and explain the hydraulic principle of force multiplication through the master cylinder and caliper pistons

Describe the correct sequence for bleeding a brake system and explain why air in the lines causes a spongy pedal

Measure brake pad thickness and rotor thickness with a micrometer and compare results to a stated minimum specification

Diagnose three written brake complaints (pulling to one side, pulsation during braking, pedal sinking slowly) and list the likely cause and confirmatory test for each

Explain the function of the proportioning valve, residual check valve, and ABS modulator in the hydraulic circuit

Identify suspension and steering components (MacPherson strut, control arm, ball joint, tie rod, rack and pinion, stabilizer bar) and state the function and wear symptom of each

Explain camber, caster, and toe, and describe the handling symptom produced by a misadjustment in each angle

Describe how to check for play in a ball joint and tie rod end using a pry bar and wheel-rock test, and state the pass/fail criteria

Interpret a written tire wear pattern (inner edge wear, cupping, center wear) and match it to a likely alignment or inflation cause

Explain the purpose of wheel balancing and the difference between static and dynamic imbalance

Trace power flow through clutch, manual transmission, propeller shaft, differential, and drive axles, and explain the function of each stage

Describe how to inspect and replace a clutch disc, pressure plate, and release bearing, including flywheel inspection and alignment tool use

Explain the operation of an automatic transmission torque converter and planetary gear set at a conceptual level, and list the checks for fluid level and condition

Diagnose three written drivetrain complaints (clutch slip, gear whine in one gear only, vibration at speed) and list the likely cause and confirmatory test for each

State the safety precautions for working under a vehicle supported on stands, including wheel chocking and stand rating

Complete two full-length timed practice sets covering all eight domains and record the score per domain

Re-study the two lowest-scoring domains by rewriting the missed concepts into a one-page summary sheet each

Rehearse the 5S and PPE routine and the safe-handling rules for batteries, brake fluid, and lifting equipment until they can be stated without notes

Review all prior deliverables and correct any errors found, noting the corrected fact beside each item
