Vehicle Diagnosis & Basic Maintenance

What is the purpose of performing vehicle diagnosis?

• To make the vehicle run faster

• To identify issues or problems with the vehicle's systems or components.

• To increase the vehicle's resale value

• To improve the vehicle's fuel efficiency

Explain the importance of basic maintenance in automotive.

• Basic maintenance is only needed for aesthetic purposes

• Basic maintenance in automotive is essential for optimal performance, longevity, and safety of the vehicle.

• Basic maintenance in automotive is optional and not necessary

• Neglecting basic maintenance has no impact on vehicle performance

List three common signs that indicate a vehicle needs diagnosis.

• Tire pressure, clean windshield, fuel level

• Dashboard warning lights, strange noises from the engine, performance issues

What are the steps involved in conducting a basic vehicle inspection?

• 1. Check exterior for damage. 2. Inspect tires. 3. Check lights. 4. Inspect fluid levels. 5. Test brakes. 6. Check steering and suspension. 7. Verify windshield wipers. 8. Ensure documentation is up to date.

• Verify radio functionality

• Check interior for damage

• Inspect engine performance

How often should basic maintenance tasks like oil change be performed?

• Every 7,000 to 9,000 miles or every 7 to 9 months

• Every 2,000 to 4,000 miles or every 2 to 4 months

• Every 3,000 to 5,000 miles or every 3 to 6 months

• Every 10,000 miles or every year

Describe the process of checking and replacing air filters in a vehicle.

• Locating the air filter housing and replacing the oil filter

• Checking the tire pressure and refilling windshield wiper fluid

• The process of checking and replacing air filters in a vehicle involves locating the air filter housing, opening it, removing the old filter, inspecting it, replacing with a new filter if necessary, ensuring proper seating, closing the housing securely, and checking for any issues.

• Inspecting the brake pads and replacing the transmission fluid

Why is it essential to monitor tire pressure regularly?

• To see how fast the tires wear out

• To test the durability of the tire pressure gauge

• To practice changing tires more frequently

• To ensure optimal fuel efficiency, tire longevity, vehicle safety, and overall performance.

What are the potential consequences of neglecting basic maintenance tasks?

• Increased efficiency, reduced safety hazards

• Improved equipment performance, reduced downtime

• The potential consequences of neglecting basic maintenance tasks include equipment failure, decreased efficiency, safety hazards, costly repairs, and shortened lifespan of assets.

• Extended lifespan of assets, reduced costs

Explain the role of fluids like engine oil and coolant in vehicle maintenance.

• Engine oil helps in charging the battery

• Engine oil is used for cleaning the windshield

• Coolant is responsible for adjusting tire pressure

• Engine oil lubricates engine components to reduce friction and wear, while coolant regulates engine temperature to prevent overheating.

List three tools commonly used for vehicle diagnosis and basic maintenance.

• OBD-II scanner, multimeter, socket set

• Tire pressure gauge, duct tape, flashlight

• Wrench, screwdriver, hammer

• Jumper cables, air freshener, GPS device
