Frequently Asked Questions

  • How does a mobile oil change service work?

    A mobile oil change brings the service directly to your home or workplace, where a technician performs the complete oil change including high-quality motor oil and filter replacement. The process takes about 30 minutes and eliminates the need to visit a shop. At RDU Auto Repair, we handle all disposal and cleanup on-site.

  • When should I replace my timing belt?

    Most manufacturers recommend timing belt replacement every 60,000 to 100,000 miles, depending on your vehicle model. Replacing it on schedule prevents catastrophic engine damage that occurs when belts snap during operation. At RDU Auto Repair, we also inspect related components during timing belt service to ensure proper valve timing.

  • What are signs my car's AC needs repair?

    Common signs include weak airflow, warm air from vents, unusual noises when AC runs, or musty odors in the cabin. These symptoms often indicate low refrigerant, compressor issues, or leaks in the cooling system. Professional diagnostics can identify the exact cause and prevent further damage.

  • How often should tires be rotated?

    Tires should typically be rotated every 5,000 to 7,500 miles to ensure even wear and maximize tire lifespan. Regular rotation prevents uneven tread patterns that can affect handling and safety. At RDU Auto Repair, we include balancing and alignment checks with tire rotation services.

  • What does an automotive diagnostic service check?

    Advanced diagnostics use professional equipment to scan engine computers, identify error codes, and pinpoint mechanical or electrical problems. This includes checking engine performance, sensor function, emissions systems, and electrical circuits. Accurate diagnostics save time and money by identifying the exact issue before repairs begin.

  • Can a water pump be repaired or does it need replacement?

    Water pumps typically require full replacement rather than repair when they fail, as internal components like bearings and seals wear out. A failing water pump causes coolant leaks and engine overheating, which can lead to serious engine damage. Replacement ensures proper coolant circulation and prevents overheating.

  • What's the benefit of replacing spark plugs on time?

    Fresh spark plugs improve engine performance, fuel efficiency, and starting reliability while reducing emissions. Worn plugs cause misfires, rough idling, and decreased gas mileage. Most vehicles need spark plug replacement every 30,000 to 100,000 miles depending on plug type and manufacturer recommendations.

  • Does Raleigh's hot summer weather affect car AC systems?

    Yes, Raleigh's humid summers put extra strain on AC compressors and can accelerate refrigerant leaks in aging systems. High temperatures also reveal weak points in cooling performance. At RDU Auto Repair, we recommend AC diagnostics before summer to ensure your system handles the heat efficiently.

  • What's included in comprehensive auto maintenance?

    Comprehensive maintenance includes fluid changes, filter replacements, belt inspections, and multi-point vehicle inspections to catch problems early. This preventive approach checks critical systems like brakes, suspension, and fluids. Regular maintenance extends vehicle life and prevents costly breakdowns.

  • What can emergency roadside assistance help with?

    Emergency roadside assistance provides jump starts, battery replacement, and on-site mechanical repairs when your vehicle is stranded. Available 24/7, this service gets you back on the road quickly without waiting for a tow. At RDU Auto Repair, we handle common roadside emergencies throughout the Raleigh area.

  • How do I know if my water pump is failing?

    Warning signs include coolant leaks under the car, engine overheating, steam from the hood, or a whining noise from the front of the engine. A failing water pump cannot circulate coolant properly, leading to rapid temperature increases. Immediate inspection prevents engine damage from overheating.

  • What's the biggest mistake people make with oil changes?

    The most common mistake is delaying oil changes beyond recommended intervals, which causes engine wear and sludge buildup. Dirty oil loses its lubricating properties and can damage internal components. Using the correct oil type for your vehicle and changing it regularly protects your engine investment.
