Diagnostics

  • 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.

    When your light comes on, it is ALWAYS important to look at the issue to see if it is a problem.  Especially if it is a light we all understand.  Tire pressure is one we all can relate to and an easy one to look at.  However, most drivers just assume the air is low in them and ignore it which is not a good idea especially when you are driving a 4x4 diesel truck off-roading and could have picked up anything and/or everything like this truck tire did. 

    He looked, and immediately headed over to see our technicians here at C H Auto Repair.
