Here's a general guide, but always consult your owner's manual for the most accurate instructions and diagrams specific to your vehicle. The manual should show you the exact location of the adjusting screws and how they affect beam direction.
General Procedure (May vary slightly):
1. Park on a level surface: This is crucial for accurate adjustment. Make sure your car is about 25 feet away from a wall or screen.
2. Turn on your headlights: You need to see the beam pattern.
3. Locate the adjustment screws: Open the hood. Look behind the headlight assemblies. You'll likely find two screws per headlight. One controls vertical adjustment (up and down) and the other controls horizontal adjustment (left and right). They might be Phillips head or other types. Sometimes they're easily visible, other times they're partially hidden behind components. A flashlight and possibly some maneuvering may be necessary.
4. Identify which screw adjusts which direction: This is where the owner's manual comes in handy. Typically:
* Vertical Adjustment: Turning the screw clockwise usually raises the beam; counter-clockwise lowers it.
* Horizontal Adjustment: Turning the screw clockwise usually moves the beam to the right; counter-clockwise moves it to the left.
5. Make small adjustments: Turn the screws very slightly. Check the beam pattern on the wall after each adjustment. A small turn can make a big difference. It's much better to make several small adjustments than one large one.
6. Adjust for proper aim: The goal is to have the headlights aimed correctly so they don't shine too high (blinding oncoming drivers) or too low (inadequate illumination). Refer to your owner's manual for the specific aiming specifications or look for markings on the headlight assembly itself.
7. Check from both sides: Repeat the process for both headlights to ensure they're aimed consistently.
Important Considerations:
* Safety First: Wear safety glasses to protect your eyes from accidental injury when working near the headlights.
* Owner's Manual: Your owner's manual is your best friend for this task. It will have diagrams and instructions specific to your 1988 Chevy Celebrity.
* Professional Help: If you're uncomfortable working on your car or can't find the adjustment screws, take it to a qualified mechanic. Improper headlight adjustment can be dangerous.
Remember, this is a general guideline. The specific location and functionality of the adjustment screws might vary slightly depending on your particular Chevy Celebrity model. Always consult your owner's manual before proceeding.
