Top 10 Questions for Automobile Service Station Mechanic Interview

1. What are the different types of engine lubricants, and what are their applications?

• Mineral oil: Refined from crude oil, mineral oil is the most common type of engine lubricant. It is suitable for most vehicles and provides good protection against wear and tear.
• Synthetic oil: Created from synthetic hydrocarbons, synthetic oil is more expensive than mineral oil but offers superior protection against wear, heat, and sludge. It is a good choice for high-performance vehicles and those that operate in extreme conditions.
• Semi-synthetic oil: A blend of mineral and synthetic oil, semi-synthetic oil offers a balance between cost and performance. It provides better protection than mineral oil and is suitable for most vehicles.

2. Describe the process of diagnosing and repairing an engine that is experiencing misfiring.

Diagnostic steps

• Check for loose or damaged spark plugs and wires.
• Test the fuel injectors to ensure they are delivering the correct amount of fuel.
• Examine the ignition coil and distributor (if applicable) for any issues.
• Check the timing belt or chain to ensure it is properly aligned.

Repair steps

• Replace any faulty spark plugs or wires.
• Clean or replace fuel injectors as needed.
• Repair or replace the ignition coil or distributor.
• Adjust the timing belt or chain to the correct specifications.

3. Explain the different types of brake systems and their advantages and disadvantages.

• Drum brakes: Drum brakes use a pair of brake shoes that expand outward to rub against the inside of a rotating drum attached to the wheel. They are less expensive and easier to maintain than disc brakes but are less effective and fade more easily under heavy use.
• Disc brakes: Disc brakes use a caliper that squeezes two brake pads against a disc attached to the wheel. They are more effective and fade less under heavy use than drum brakes but are more expensive and more difficult to maintain.
• Anti-lock braking systems (ABS): ABS prevents the wheels from locking up during braking, which can lead to loss of control. ABS systems use sensors to monitor wheel speed and automatically reduce braking pressure to individual wheels when they detect a lockup.

4. How do you diagnose and repair a vehicle that is experiencing a loss of power?

• Check the air filter for clogs or restrictions.
• Inspect the fuel system for leaks or blockages.
• Examine the spark plugs and wires for wear or damage.
• Test the fuel injectors to ensure they are delivering the correct amount of fuel.
• Check the compression in the engine to ensure it is within specifications.

5. Explain the purpose and operation of the transmission system in a vehicle.

• The transmission system in a vehicle is responsible for transferring power from the engine to the wheels.
• There are two main types of transmissions: manual and automatic.
• Manual transmissions require the driver to manually shift gears, while automatic transmissions do so automatically.
• The transmission system also includes the clutch, which allows the driver to engage and disengage the transmission from the engine.

6. How do you perform a wheel alignment and what are the benefits of doing so?

• Procedure:
  • Place the vehicle on a lift.
  • Attach wheel alignment targets to each wheel.
  • Use an alignment machine to measure the angles of the wheels.
  • Adjust the suspension components as necessary to align the wheels.
• Benefits:
  • Improved handling and stability.
  • Reduced tire wear.
  • Improved fuel economy.

7. Explain the role of the emission control system in a modern vehicle.

• The emission control system in a modern vehicle is designed to reduce the amount of pollutants released into the environment.
• The main components of the emission control system are the catalytic converter, the exhaust gas recirculation (EGR) system, and the oxygen sensor.
• The catalytic converter converts harmful emissions into less harmful substances.
• The EGR system recirculates some of the exhaust gas back into the engine to reduce the combustion temperature and thus reduce emissions.
• The oxygen sensor monitors the amount of oxygen in the exhaust and provides feedback to the engine control unit (ECU) to adjust the air-fuel mixture.

8. How do you troubleshoot and repair a vehicle that is experiencing electrical problems?

• Check the battery for loose or corroded connections.
• Inspect the alternator and voltage regulator to ensure they are functioning properly.
• Examine the wiring and fuses for any damage or breaks.
• Use a multimeter to test the electrical system and identify any faults.

9. Explain the importance of regular vehicle maintenance and what are the typical services that should be performed?

• Regular vehicle maintenance is important to keep the vehicle running smoothly and safely.
• Typical maintenance services include:
  • Oil changes
  • Tire rotations
  • Brake inspections
  • Fluid flushes
  • Filter changes
• By following the manufacturer’s recommended maintenance schedule, you can help extend the life of your vehicle and avoid costly repairs.

10. How do you stay updated with the latest advancements in automotive technology?

• Attend industry conferences and workshops.
• Read automotive trade publications and websites.
• Take online courses and tutorials.
• Network with other automotive professionals.
