More on Our Most Popular Auto Repair & Maintenance Services

  • Alignments


    Regular wheel alignments keep your car running safely and efficiently by reducing tire wear, improving gas mileage, and promoting safer driving conditions. When left untreated, wheel alignment problems have the potential to turn into steering and suspension issues because driving with wheels out of alignment not only puts stress on your tires but also on suspension components. We’re alignment experts at Carlock Auto—our mechanics will make sure any alignment or balance issues you’re experiencing are totally smoothed out.

  • Air Conditioning

    A/C – Air Conditioning

    Your vehicle’s A/C is part of the HVAC (heating, ventilation, and air conditioning) system, and one of the most important parts of the comfort-control center. What we don’t have to tell you is that when your A/C isn’t working properly, driving can be miserable and, in some cases, even dangerous in the mid-summer heat and humidity. Our mechanics can help if you’re experiencing low or no vent air flow, improper vent air temperature (i.e. not as cold as it should be), bad smells, noises during A/C operation, or overheating.

  • Diagnostics


    Is your check engine light on? Is your car intermittently stalling or not starting? Then it’s time for a trip to the diagnostic experts at Carlock Auto Servicenter. In the Carlock area, we’re known for our diagnostic skill, and making precise repairs. Some auto repair shops “fix” a bunch of potential issues without knowing the exact cause of the problem, but hoping they hit upon it. Not us. Our technicians never perform unnecessary auto repairs, and we believe you should never have to go to the auto repair shop twice for the same issue.

  • Electrical Repair

    Problems involving automotive electrical systems can cause complicated and frustrating issues that aren’t always easy to identify, understand, and repair correctly. However, with years of experience, proven auto electrical know-how, and up-to-date equipment, our auto electrical service experts can solve any exterior or interior electrical problem, no matter how complex. From a repeat dead battery to a misfiring starter to dimming headlights or dashboard issues, we can diagnose and repair all types of electrical malfunctions.

  • Transmission Flush

    Transmission Flush

    Routine fluid and filter maintenance is the easiest way to ensure the longevity and performance of your vehicle’s transmission and to avoid costly transmission repairs or the need for a transmission rebuild or replacement. Let us check the quality of your transmission fluid if you’ve never had a transmission flush, and we’ll let you know if it’s in your vehicle’s best interests. You can trust us to give you an honest recommendation based on our professional assessment and the age and condition of your vehicle.

  • Tune-ups


    A simple maintenance tune-up can make your engine easier to start, improve your fuel economy, and restore your vehicle’s pep and power, while identifying issues that may cause you problems down the road. As part of a tune-up, we’ll check your battery voltage, power balance, engine vacuum, idle speed, and your ignition timing. In addition to these performance checks, we’ll inspect your belts, hoses, and fluids. Then for preventive maintenance, we’ll replace your spark plus (if required), and filters and fluids as necessary.
