Frequently Asked Questions

  • What causes a check engine light to come on?

    A check engine light can indicate issues ranging from a loose gas cap to serious engine problems like oxygen sensor failure, catalytic converter issues, or misfiring cylinders. Advanced diagnostic equipment is needed to read the specific trouble codes. At Napoli Automotive, we use expert diagnostic tools to pinpoint the exact cause quickly.
  • How often should you get an oil change?

    Most vehicles need an oil change every 3,000 to 5,000 miles with conventional oil, or up to 7,500 miles with synthetic oil. Check your owner's manual for manufacturer recommendations. Regular oil changes using quality motor oil and filters help maintain engine performance and prevent costly repairs.
  • What are signs your brake pads need replacing?

    Squealing or grinding noises, longer stopping distances, vibration when braking, or a brake warning light are common signs. Brake pads typically need replacement every 25,000 to 70,000 miles depending on driving habits. At Napoli Automotive, we include brake pad replacement and rotor resurfacing in our complete brake services.
  • When should you replace your car's timing belt?

    Most timing belts should be replaced every 60,000 to 100,000 miles, as specified in your vehicle's maintenance schedule. Failure to replace a worn timing belt can cause severe engine damage. Weatherford, TX drivers should follow manufacturer intervals to avoid costly engine rebuilds.
  • How do you know if your suspension needs repair?

    Symptoms include excessive bouncing, uneven tire wear, steering drift, or clunking noises over bumps. Poor suspension affects vehicle handling and safety, especially on Weatherford's varied road conditions. Professional suspension inspections can identify worn shocks, struts, or steering components early.
  • What's included in preventive vehicle maintenance?

    Preventive maintenance includes oil changes, tire rotations, fluid checks, filter replacements, and scheduled services per your owner's manual. Regular maintenance keeps vehicles in optimal condition, improves fuel efficiency, and prevents unexpected breakdowns. Following the manufacturer's schedule protects your investment long-term.
  • Why does my transmission shift roughly?

    Rough shifting often results from low transmission fluid, worn clutch components, or dirty fluid causing friction issues. Transmission fluid changes and regular maintenance ensure smooth shifting and drivetrain performance. Ignoring transmission problems can lead to expensive repairs or complete transmission failure.
  • Can a bad alternator drain your battery?

    Yes, a failing alternator won't properly charge the battery, causing it to drain and eventually leave you stranded. Warning signs include dimming lights, electrical issues, or dashboard warning lights. At Napoli Automotive, we diagnose and replace alternators, starters, and batteries as part of electrical system repair.
  • How long do tires typically last?

    Quality tires generally last 40,000 to 70,000 miles depending on driving habits, road conditions, and maintenance. Regular tire rotations and proper inflation extend tire life significantly. High-quality tire sales and professional installation enhance both driving experience and vehicle safety.
  • What's the difference between a tune-up and diagnostics?

    A tune-up involves replacing spark plugs, filters, and other wear items to maintain performance, while diagnostics use computer equipment to identify specific problems causing issues like engine lights or poor performance. Both services address different needs in comprehensive vehicle repair.
