Maintenance

None of this is expert advice. It's what people worked out for themselves, usually the hard way — what actually helped, and what they'd tell someone standing where you are. Take what fits and leave the rest.

How this was put together

If you only read a few

  1. Wear gloves or use a clean cloth when handling halogen headlight bulbs to prevent skin oils from touching the glass.

    Skin oils can cause uneven heating, thermal stress, hot spots, or cracks that lead to premature failure or shattering.

    • This mainly applies to halogen and arc bulbs.

  2. If you raise your vehicle or fit new lights, use adjustment screws to align the headlights.

    Headlights are set for a specific ride height; not adjusting them can blind other drivers.

  3. Run your car's AC for at least 10 minutes once a month.

    It helps prevent the system from going moldy.

  4. Keep a headlamp in your car to make changing tires and other roadside tasks easier.

    It makes the work much easier.

  5. Fix small car issues like rust or dents early to prevent them from becoming big, expensive problems.

    Rust is difficult to get rid of once it sets in.

  1. Use a dedicated plastic polish, such as Plastix, to restore headlight lenses instead of harsh chemicals.

    Plastix was tested against five other brands and found to work best and last longest.

  2. Replace both headlight bulbs when one burns out to ensure matching beams, though some argue this wastes money if the other bulb lasts years.

    Headlights tend to have the same approximate lifetime, so the other may burn out soon; however, there is no guarantee it will break soon.

    • Some sources state this is false and a waste of money, as bulbs can last years between replacements.

  3. Fix burnt-out low beam headlights immediately rather than relying on high beams.

    High beams blind oncoming drivers and are not a permanent fix.

  4. If you drive a manual transmission car, avoid resting your hand on the gear stick or using heavy aftermarket knobs to prevent transmission damage.

    It could lead to transmission troubles down the line.

  1. Understand that salt smooths glass by burnishing rather than polishing.

    Salt is too soft to scratch the amorphous glass, so it pushes and smoothes it out instead.

  2. Use a Bluetooth OBDII scanner to look up error codes online before taking your car to a mechanic.

    Identifying simple issues like a loose gas cap can save significant repair costs compared to vague descriptions like 'check engine light is on'.

  3. Avoid putting baking soda in AC vents.

    When water evaporates, the baking soda remains and can clog airflow.

  4. If you are financially struggling, learn to perform low-skill maintenance tasks like oil changes and brake jobs yourself.

    Getting these done professionally is considered a luxury.

  5. Use the nitrogen station at the Tire Center to fill tires to the correct pressure automatically.

    The gauge fills the tire to the selected pressure.

  6. Apply a tiny bit of dielectric grease to the base of lightbulbs before installation to prevent them from sticking.

    It prevents issues removing burnt bulbs later.

  7. Use small reusable dehumidifier beads, like those for gun safes, to passively absorb moisture in vehicles.

    They suck up moisture and change colors to indicate humidity levels.

  8. Scrub headlight lenses with toothpaste and a wet sponge to remove oxidized coating.

    Toothpaste is a fine abrasive that takes off the oxidized coating.

  9. Ignore minor scratches on plastic bumpers if you are prioritizing frugality, as they are hardly noticeable and will not rust.

    Plastic does not rust, and the damage is far from a necessity to fix immediately.

  10. Investigate underlying vehicle issues, such as voltage regulation or intense vibration, if headlights burn out simultaneously.

    Simultaneous failure typically indicates something else is wrong with the vehicle.
