Vehicle Maintenance & Inspection Flashcards

How often should you check your vehicle's engine oil level?

Answer: At every fuel fill-up or at least monthly

Checking oil at every fill-up or monthly helps catch leaks or burning oil before engine damage occurs.

What does a vehicle's tire pressure monitoring system (TPMS) warning light indicate?

Answer: One or more tires are significantly under-inflated

The TPMS light illuminates when tire pressure drops 25% or more below the recommended PSI.

Which component should be inspected if your vehicle pulls to one side while braking?

Answer: Brake calipers or pads

Uneven brake pad wear or a stuck caliper causes the vehicle to pull toward the side with more braking force.

What is the purpose of the PCV (Positive Crankcase Ventilation) valve?

Answer: Recirculates harmful crankcase gases back into the intake

The PCV valve prevents pressure buildup and reduces emissions by routing crankcase gases to be burned in the engine.

When should you replace your vehicle's cabin air filter?

Answer: Every 15,000–25,000 miles or per manufacturer recommendation

Cabin air filters trap dust and pollen for the HVAC system and typically need replacement every 15,000–25,000 miles.

A musty smell from your car's air conditioning is most likely caused by:

Answer: Mold or bacteria growth in the evaporator

Moisture accumulates on the evaporator core, creating an environment where mold and bacteria thrive.

Which fluid is responsible for transferring heat away from your vehicle's engine?

Answer: Coolant (antifreeze)

Coolant circulates through the engine and radiator to absorb and dissipate excess heat.
