  • Recognizing Flood Damage When Buying A Vehicle

    Unless you are confident in your abilities as an automotive mechanic, there is really only one rule when purchasing a flood-damaged vehicle: don’t do it. Unfortunately, sometimes sellers aren’t particularly straight-forward with their used cars. Many will try to hide the fact that it’s been damaged by floodwaters at all or try to convince potential buyers that the car is in fact fine. “It has gone months with no issues” or “technically it is flood-damaged but” are two red flags, and while it isn’t impossible for a flood car to be fine, it’s altogether a good idea to stay away.

  • Reduce Noise and Increase Fuel Mileage

    While your exhaust system helps reduce noise output from your vehicle, it also significantly reduces harmful emissions from being released into the air. When your muffler and exhaust system are functioning properly, it significantly reduces your vehicle's harmful impact on the environment. It also significantly improves the functionality of your vehicle and improve fuel mileage for your car, truck, SUV or Jeep.

    An exhaust system is made up of numerous parts that work together to rid your car of the exhaust gases that are created during the combustion cycle, as your engine burns fuel. Each part of your exhaust system has an important role to play in removing exhaust gases away from the engine as quickly as possible, allowing another cycle of combustion to begin. The more quickly and efficiently an exhaust system does this the more efficiently an engine can run. The main parts of an exhaust system are an exhaust manifold, catalytic converter, oxygen sensors, exhaust pipes, and the muffler.

    Here at Dennis Road Automotive in Dallas we often do diagnostics and sometimes the problem is obvious after hooking the car up to the computer and reading the codes.  However, sometimes it isn't obvious during a test drive or after hooking it up to all those computer programs!  You know there is a problem and a Check Engine Light is on with the fleet customer telling you the car has been having issues starting and the light has been going off and on depending on several factors.  No pattern, no simple answer but the problem becomes obvious when you start following the "threads of the issue" thanks to all that ASE Technician training.
