More on Our Auto Service Expertise

  • Alternators

    Alternators

    The alternator is part of your vehicle’s charging system, and it’s critical to keeping your car operable. Everything, including your battery, depends on your alternator. Warning signs your alternator requires repair or replacement include dimming headlights, noise, the smell of burning rubber, and loss of power. But no matter what symptoms you’re experiencing, we can help. If you suspect an issue with your alternator, please allow us to take look and help you get back on the road again, confident your car will start and drive.


  • Brake Repair & Service

    Brake Repair & Service

    At 1-Stop Automotive, we’re experts in all phases of brake repair and service, including brake rotor replacement, front disc brake repair, parking brake adjustment, rear disc brake repair, rear drum brake repair, and anything else your brakes require. Although braking systems vary from vehicle to vehicle, the responsibility and importance of the components remains the same. From brake pedal to brake fluid to brake pads, calipers, lines, and hoses, let us make sure you’re ready to stop when you need to with comprehensive brake service.


  • Suspension Repairs & Wheel Alignments

    Suspension Repairs & Wheel Alignments

    Modern vehicles benefit from more precise and complex suspension systems than in the past, which means suspension system components have become increasingly critical for your car’s overall performance. If you’re experiencing a shaky, rough ride, your struts and/or shocks could be the problem, or you may need another type of frontend service, like a wheel alignment. Our mechanics can handle any suspension repairs you need, and we’re experts at wheel alignments, with state-of-the-art wheel alignment equipment.


  • Timing Belt Replacement

    Timing Belt Replacement

    If your timing belt fails, so does your engine, and your car shuts down. So, when a reputable mechanic tells you that you need a new timing belt, you’d be wise to listen. However, there aren’t many obvious signs a timing belt is ready to break, which is why many drivers get a timing belt replacement as a preventive maintenance service. Let us know how long you’ve owned your car, and whether you’ve ever had the timing belt replaced, and we’ll let you know—honestly—if it’s time for a new timing belt.


  • Tune-ups

    Tune-ups

    When your vehicle is properly tuned, the ignition system, fuel system, emission system, and computer system are all working together in perfect harmony. When they are not, you need a tune-up. As part of a tune-up, we’ll check and replace (as necessary) your spark plugs, ignition coils, distributor cap, rotor, and ignition wires. Afterward, you’ll enjoy improved vehicle performance, and likely save money at the gas pump. At 1-Stop Automotive, we don’t use tune-ups to sell other services, but to keep your vehicle running stronger longer.


  • Water Pumps

    Water Pumps

    Your vehicle’s water pump circulates coolant around the engine and through the cooling system passageways to the radiator where the coolant temperature is reduced. Even a small water pump leak can suddenly enlarge, or the water pump bearing might unexpectedly seize. Either situation can cause engine overheating and engine damage. Our mechanics can determine if you need a water pump replacement based on the condition of the water pump bearing, belts and hoses, and other cooling system components.
