Which adjustment should be checked after hood replacement to ensure proper visibility?

• A. Tire pressure
• B. Parking brake adjustment
• C. Mirror alignment
• D. Headlight aim adjustment

Answer: (D)

Visibility is affected by where the headlights point, so after hood replacement you must recheck and set headlight aim. The hood can slightly shift mounting points or change how the headlight assemblies sit, which can move the beams up, down, or to the sides. If the aim isn’t correct, you might blind others or fail to illuminate the road properly. Re-aiming the headlights to the manufacturer’s specifications ensures the beam pattern is directed where you need it for safe nighttime visibility. Use a level surface, follow the service manual’s procedure, and verify both vertical and horizontal alignment with the normal inspection setup.

Tire pressure, parking brake adjustment, and mirror alignment don’t affect where the headlights project light, so they don’t address visibility in the same way after hood work.
