Question 1
Answer 1
AC CompressorThe air conditioning compressor is used to compress refrigerant gas, and then delivers it to the condenser. If not replaced, the AC Compressor will eventually fail and cause your air conditioner to not cool properly.
Question 2
Answer 2
Crankshaft SensorA crank sensor is a component used to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. If not repaired, a faulty crankshaft sensor will cause the crankshaft to function improperly. The crankshaft is one of the core components of the engine and when it fails to work properly, it is leaving the other core components of the engine vulnerable to major damage.
Question 3
Answer 3
Ball Joint ReplacementThe ball joint allows the suspension to pivot when steering and to move up and down as road surfaces become rough or uneven. Without the pivoting motion afforded by the ball joint, steering a vehicle would be impossible. If not replaced, a worn upper ball joint developsexcess clearance. A worn ball joint may develop acreaking sound when the suspension moves up and down while driving on an uneven road surface, andwill contribute to excessive inner or outer tire wear
Question 4
Answer 4
Intake Manifold GasketsThe intake manifold gasket is a malleable material that is set between the air intake manifold, the cylinder heads and the block in a gasoline powered internal combustion engine. Intake manifold gaskets prevent leakage of air or the air-fuel mixture by sealing the gap between these various metal engine parts. If not replaced, a leaking intake manifold gasket will contribute to poor fuel economy, higher emissions and poor engine performance.
Question 5
Answer 5
Starter ReplacementBy harnessing the power of the battery, the starter motor powers the car’s engine to "turn over," or start when the driver turns the ignition switch. If not replaced, a malfunctioning starter will make an unusual noise when the vehicle is starting and eventually be incapable to cause the engine’s crankshaft to turn, which starts the engine running.
Question 6
Answer 6
AC EvaporatorThe air conditioning evaporator cools anddehumidifies air in the passenger compartment of the vehicle. If not replaced, the A/C Evaporator will fail, causing the air conditioning system to not function properly.
Question 7
Answer 7
Transmission Cooler LineTransmission cooler lines deliver vital fluids to the transmission and all its internal components. If the Transmission Cooler lines are not replaced when needed, the Transmission fluid that not only allows the gears to change but also prevents it from overheating cannot be properly delivered.
Question 8
Answer 8
Radiator Hose ReplacementAn engine has two radiator hoses: lower and upper. The lower hose brings coolant (a mixture of water and antifreeze) that has been cooled in the radiator to the engine, where it circulates and absorbs heat. The upper hose carries hot coolant from the engine back to the radiator to be recooled. The radiator hoses are located between the radiator and the engine block If not replaced, radiator hoses, which are madefrom rubber so they deteriorate over time, will crack and leak causing the engine to run hot or overheat.
Question 9
Answer 9
Valve Cover Gasket Prevents loss of engine oil and keeps surrounding area free of oil residue. If not replaced, the engine will leak oil from thevalve cover which can result in a burning smellcoming from the vehicle’s engine.
Question 10
Answer 10
Floor Shifter AssemblyThe vehicles floor shifter assembly attaches to the upper portion on the transmission allowing the driver to shift from gear to gear seamlessly. A damaged shifter assembly may lead to issues when changing gears and in some severe cases it can affect the internal components of the transmission.
Question 11
Answer 11
Windshield Washer PumpThe windshield washer pump allows fluid to beextracted from the reservoir where it is thenpumped through the washer nozzles onto thewindshield. A faulty pump needs to be replaced immediately as it is considered a safety hazard if broken.
Question 12
Answer 12
Radiator Replacement:The engine generates heat when it is running; this heat must be removed to prevent damage to the engine. Coolant circulates throughout the engine and absorbs this heat. The water pump pushes the coolant through the radiator (where it is cooled) and returns it to the engine once more to absorb the engine’s heat, before returning it to the radiator to be cooled again. If not replaced, a corroded and leaking radiator will cause the engine to overheat.
Question 13
Answer 13
AC Condenser ReplacementThe air conditioning condenser acts as a heatexchanger, cooling the compressed air conditioning refrigerant and turning it from a vapor into a liquid. If not replaced, the AC Condenser will fail and the AC Compressor will eventually fail and cause your air conditioner to not cool properly.
Question 14
Answer 14
Steering RackThe steering wheel is attached to the steering rack by the steering shaft. When the steering wheel is turned, the steering rack interprets the directional input and pushes or pulls the front wheels in the desired direction. The steering rack is secured to the chassis. If not replaced, a failing steering rack may clunk when turning or when going over bumps while driving. A failing steering rack will also cause difficulty in steering.
Question 15
Answer 15
Rocker ArmsA rocker arm consists of a curved lever that pivots in the middle. One end is attached to the top of the valve stem. In overhead-valve engines the other end is attached to the pushrod. In someoverhead-cam engines the other end is attached directly to the camshaft lobe. As the camshaft rotates, the rocker arms pivot causing the valves to open and close. If not repaired, a faulty rocker arm will prevent the engine valves from operating at optimalperformance or operating altogether. Precise valve functioning is a crucial part of engine performance and in many situations the engine will cease to run without it.
