ASE PS2 Test Preparation Guide: Electrical System
The major components in the electrical system include the battery, starter and alternator. Also included are the battery cables, relays, fuses and bulbs.
ASE PS2 Test Preparation Guide: Emission Control Systems
Emission control systems include the engine management system (PCM and sensors), Positive Crankcase Ventilation (PCV) system, Exhaust Gas Recirculation (EGR), the Evaporative Emission Control System (EVAP) and catalytic converter.
ASE PS2 Test Preparation Guide: Exhaust System
The major components in the exhaust system include the exhaust manifold, head pipe, Y-pipe (if used), exhaust pipe, crossover pipe, tailpipe, muffler, resonator, catalytic converter, clamps, hangars and heat shields.
ASE PS2 Test Preparation Guide: Fuel System
The major components in the fuel system include the fuel pump, fuel filter, fuel lines, fuel injectors, fuel pressure regulator, throttle body, fuel tank and gas cap.
ASE PS2 Test Preparation Guide: Gaskets
Engine gaskets include head gaskets, valve cover and pan gaskets, intake and exhaust manifold gaskets, timing cover gaskets, thermostat and throttle body gaskets, valve guide seals, and crankshaft and camshaft seals. Gaskets are sold individually or in sets that include all of the gaskets and seals needed for a particular repair job (such as replacing an intake manifold, timing cover, cylinder head or overhauling the engine).
ASE PS2 Test Preparation Guide: Ignition System
The major components in the ignition system include the spark plugs, spark plug wires (if used), ignition coil(s), ignition module (if used), an ignition pickup (in a distributor) or a crankshaft position sensor, and on older engines, a distributor.
ASE PS2 Test Preparation Guide: Manual Transmission/Transaxle
The major components in a manual transmission or transaxle include the clutch, release bearing, pilot bearing (if used), clutch linkage (hydraulic or cable), gearbox and shift linkage.
ASE PS2 Test Preparation Guide: Steering & Suspension
The major components in the steering include the steering gear (rack & pinion or recirculating ball), power steering pump and hoses (if used), tie rods and tie rod ends, idler arm and center link (if used) and steering stabilizer (if used). The major components in the suspension include springs, shock absorbers and/or struts, control arms and bushings, ball joints, and sway bar and bushings.
Rotors On A Microscopic Level
When you compare rotors side-by-side, they may look the same. But, the difference between a comeback and satisfied customer might be at the microscopic level.
Bearing Q&A: The Ins and Outs of Bearings
On a typical passenger vehicle weighing around 3,400 pounds, each pair of front-wheel bearings, as well as the rear-wheel or axle bearings, support around 850 pounds, depending on the weight balance and driveline configuration.
