OMV Vehicle Maintenance 2 — Questions and Answers
Question 1: How often should you typically check your vehicle's tire pressure?
- Once a year
- At every oil change only
- At least once a month and before long trips (Correct answer)
- Only when a tire looks flat
Correct answer: At least once a month and before long trips
Tire pressure should be checked at least monthly and before long trips because tires lose pressure naturally over time.
Question 2: What does it mean when your vehicle's temperature gauge moves into the red zone while driving?
- The heater is working efficiently
- The engine is overheating and you should stop safely (Correct answer)
- The air conditioning is too cold
- The oil pressure is too high
Correct answer: The engine is overheating and you should stop safely
A temperature gauge in the red zone indicates the engine is overheating; continuing to drive can cause severe engine damage.
Question 3: Which of the following is the correct way to check engine oil level?
- Check it while the engine is running
- Check it immediately after turning off a hot engine
- Check it on a level surface with the engine off and cooled (Correct answer)
- Check it only at a service station
Correct answer: Check it on a level surface with the engine off and cooled
Engine oil should be checked on a level surface with the engine off and cooled so oil settles back into the pan for an accurate reading.
Question 4: What is the purpose of rotating your vehicle's tires?
- To improve fuel economy only
- To promote even tread wear and extend tire life (Correct answer)
- To make the ride softer
- To improve the vehicle's top speed
Correct answer: To promote even tread wear and extend tire life
Tire rotation moves tires to different positions so they wear evenly, extending their lifespan and maintaining balanced handling.
Question 5: Your power steering feels unusually stiff or difficult. What is the most likely cause?
- Brake fluid is low
- Power steering fluid is low or the belt is worn (Correct answer)
- The engine air filter is clogged
- The windshield washer fluid is empty
Correct answer: Power steering fluid is low or the belt is worn
Low power steering fluid or a worn/broken power steering belt are the most common causes of stiff or difficult steering.
Question 6: What should you do if your 'Check Engine' light comes on while driving?
- Ignore it if the car seems to run fine
- Have the vehicle's diagnostic codes read by a technician soon (Correct answer)
- Immediately stop the vehicle on the highway
- Add more fuel to the tank
Correct answer: Have the vehicle's diagnostic codes read by a technician soon
A 'Check Engine' light signals the onboard diagnostic system detected a fault; a technician should read the codes promptly to prevent further damage.
Question 7: When should you replace your vehicle's windshield wiper blades?
- Only when they completely stop working
- Every 10 years regardless of condition
- When they streak, skip, or squeak during use (Correct answer)
- Only after a vehicle inspection fails
Correct answer: When they streak, skip, or squeak during use
Wiper blades should be replaced when they streak, skip, or produce noise, as worn blades reduce visibility in rain.
