  • Engine Repair & Tune Ups

    It probably goes without saying, but the engine is the heart of your vehicle. Most people understand how important their engine is but are nervous to look into any issues regarding it, knowing that engine repairs can be expensive. With Patriot Auto Service, you can rest assured that your engine is in the hands of trained, experienced professionals that offer superior service at affordable prices. Any time you notice engine issues with your car or truck, you should have it checked by our automotive experts as soon as possible.

However, there are other signs of engine trouble you should look out for. These include:

    • Large amounts of white exhaust smoke
    • Knocking sounds during vehicle use
    • Metal flakes in your oil
    • Loss of power while driving, frequent stalls, or rough idles

  • Steering System

    Many auto issues can get away from us – even going unnoticed for long periods of time. However, if there’s a problem with your steering system, you’ll know immediately when you try to turn a corner. Even though it’s not the first thing you think of when it comes to auto maintenance, your power steering should be regularly checked to avoid unexpected breakdowns when you’re on the road. On top of bringing your car or truck into our shop for steering system inspections, make sure you have it checked out by our experts if you notice:

    • Steering your vehicle at low speeds feels heavy or unresponsive
    • Strange noises when turning your steering wheel
    • Your steering wheel shakes during vehicle use
    • The steering wheel won’t properly return to “center”
    • Strange fluid leaks from under the vehicle

    With help from our expert mechanics, your steering system will stay in perfect working order!

  • Vehicle Inspections

    On top of keeping your car functioning properly, we can help keep your car legal with vehicle inspections and emissions testing. During a vehicle inspection, our auto specialists give your car or truck a thorough exam, making sure all of your systems are functioning properly and within state and federal regulations. With an emissions test, we make sure your vehicle isn’t leaking dangerous substances to the environment, risking the health of local communities. Whether your vehicle needs maintenance, repairs, or inspections, Patriot Auto Service is here to help!

  • Wheel Alignment

    New tires won’t last long if your wheels aren’t properly aligned. Eventually, a poor alignment will cause uneven tire wear, which can cost you in the long run. Additionally, alignment issues can impact your gas mileage. If you notice any of the following indications of your wheels being out of alignment, bring your vehicle into our shop as soon as possible.

    • Your car or truck pulls to one side while driving
    • The steering wheel vibrates during vehicle use
    • When your steering wheel is off-center, you have to hold it tight.

    Our mechanics are experts at auto wheel alignments. Contact our shop today for more information!
