ASE Auto Maintenance & Light Repair 2 — Questions and Answers
Question 1: A vehicle's tire shows a recommended inflation pressure of 32 psi on the door placard, but the sidewall reads 'Max 44 psi.' Which pressure should be used for normal driving?
- 44 psi from the sidewall
- 32 psi from the door placard (Correct answer)
- Halfway between the two values
- Whatever the gauge reads when warm
Correct answer: 32 psi from the door placard
The door placard lists the vehicle manufacturer's recommended pressure for proper handling and wear, while the sidewall lists only the tire's maximum.
Question 2: When rotating tires on a front-wheel-drive vehicle using the modified-X pattern, where do the rear tires move?
- Straight to the front on the same side
- Crossed to the opposite front corners (Correct answer)
- They stay in place
- Diagonally to the opposite rear corners
Correct answer: Crossed to the opposite front corners
On FWD vehicles the rear tires cross to the opposite front positions while the fronts move straight back.
Question 3: A technician finds the engine oil level above the full mark on the dipstick. What is the most likely consequence if left uncorrected?
- Improved lubrication
- Crankshaft aeration and foaming of the oil (Correct answer)
- Lower operating temperature
- Increased fuel economy
Correct answer: Crankshaft aeration and foaming of the oil
Overfilled oil can be whipped by the crankshaft, causing aeration and foaming that reduces lubrication.
Question 4: Which tool is correct for accurately tightening lug nuts to manufacturer specification?
- Impact wrench at full power
- Torque wrench (Correct answer)
- Breaker bar by feel
- Adjustable wrench
Correct answer: Torque wrench
A torque wrench applies the exact specified torque, preventing warped rotors and stripped studs.
Question 5: A customer complains of a squealing noise that disappears when the brake pedal is pressed. What is the most likely cause?
- Worn brake pad wear indicators contacting the rotor (Correct answer)
- Low brake fluid
- Air in the lines
- A seized caliper piston
Correct answer: Worn brake pad wear indicators contacting the rotor
Wear indicators squeal against the rotor and quiet down when pads are forced against the rotor under braking.
Question 6: What does the acronym used on a maintenance schedule, 'OEM,' refer to?
- Oil Economy Maximizer
- Original Equipment Manufacturer (Correct answer)
- Onboard Emission Monitor
- Outer Edge Measurement
Correct answer: Original Equipment Manufacturer
OEM refers to parts and specifications from the original equipment manufacturer.
Question 7: Before lifting a vehicle on a frame-contact lift, the most important step is to:
- Disconnect the battery
- Position the lift pads at the manufacturer's designated lift points (Correct answer)
- Drain the coolant
- Remove the wheels
Correct answer: Position the lift pads at the manufacturer's designated lift points
Lift pads must contact the manufacturer's designated points to safely support the vehicle.
