FAQs

  • Q. "Why is my engine making bucking sounds when I drive?"
    The fuel system is a good place to investigate first whenever your engine starts to give you problems. The two most common issues we see are clogged fuel filters and damaged fuel pumps. Both of these will harm your engine if not taken care of promptly.
  • Q. "What are fuel filters?"
    Fuel injectors are easily clogged due to their small openings. They are susceptible to the dirt particles that your car drives through on the road. It’s important that the fuel remains clean and free of dirt so that it can be easily sent to the engine. The fuel filters ensure the fuel is protected from dirt. Typically, filters are made from a paper material that is thrown away and replaced when it becomes too dirty or worn out. Sometimes, cars will have filters that use a mesh material. These can be washed and then put back in the vehicle.
  • Q. "How do fuel filters affect the fuel pump?"
    Clogged fuel filters make it hard for the fuel pump to deliver gas to the engine. If the filter is blocked with dirt, the pump has to work a lot harder to pump the fuel. This will cause it to wear out and unable to perform over time.
  • Q. "Do you offer a shuttle service?"
    Yes! we understand you have a full schedule. Whether you need to get to work, school, or need to attend to other responsibilities, we can take you where you need to go. Click here to learn more.
  • Q. "Do you offer a warranty?"
    As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a 3-year/36,000-mile warranty on all the work that we do. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
  • Q. "Can you provide service under my extended warranty?"
    Yes. At Christian Brothers Automotive, we work with all major extended warranty providers to make needed repairs for our customers. If you have an extended warranty, you can discuss your carrier with our team when scheduling an appointment and confirm that the work will be covered. You can find a partial list of the extended warranty companies we work with here.
