• To improve tire pressure.

• To change the car's color.

Describe the function of a spark plug in an engine.

• The function of a spark plug in an engine is to ignite the air-fuel mixture in the combustion chamber.

• To measure the engine's temperature.

• To cool the engine by circulating coolant.

• To filter the air entering the combustion chamber.

What are the common symptoms of a failing battery?

• Difficulty starting the vehicle, dimming headlights, electrical issues, swollen battery case.

• Overheating engine

• Low fuel level

• Flat tires

How do you check the coolant level in a vehicle?

• Inspect the oil level instead of the coolant level.

• Add more coolant without checking the level first.

• Check the coolant level by inspecting the reservoir and ensuring it is between the minimum and maximum marks.

• Check the coolant level by measuring the temperature of the engine.

What is the importance of tire pressure in vehicle safety?

• Tire pressure affects fuel efficiency but not safety.

• Tire pressure is important for maintaining vehicle safety by ensuring proper traction, handling, and braking.

• Tire pressure is irrelevant for off-road vehicles.

• Higher tire pressure always improves vehicle performance.

Explain the role of the alternator in a vehicle's electrical system.

• The alternator provides power to the headlights only.

• The alternator generates electrical power and charges the battery in a vehicle's electrical system.

• The alternator controls the vehicle's speed.

• The alternator is responsible for starting the engine.

What tools are commonly used for vehicle diagnostics?

• Tire pressure gauges

• OBD-II scanners, multimeters, diagnostic software

• Windshield wiper fluid

• Oil change kits

What does the term 'brake fade' refer to?

• Brake fade refers to the sound made by brakes when applied.

• Brake fade is the process of enhancing brake responsiveness.

• Brake fade is a technique for improving fuel efficiency.

• Brake fade is the reduction in braking performance due to overheating of the brakes.

List three safety regulations that must be followed when working on vehicles.

• Ignore the need for safety glasses when working on vehicles.

• Use a regular car jack without any additional support.

• Wear appropriate personal protective equipment (PPE) such as gloves and safety glasses. Use jack stands or ramps to securely support the vehicle when working underneath it. Follow safe lifting practices, including using proper lifting techniques and equipment.

• Lift heavy parts without assistance or proper technique.

What is the function of the fuel pump in an engine?

• To filter impurities from the fuel.

• To transport fuel from the tank to the engine.

• To ignite the fuel in the combustion chamber.

• To cool the engine components.
