Your vehicle's exhaust system has two primary functions. The first is to ensure that it converts and eliminates any gases that have been generated by the vehicle out via the car's tailpipe. Secondly, it works toward preventing any gases from making their way into the interior of the vehicle as these gases could prove to be toxic to the passengers on board the vehicle. This is why any symptoms of car exhaust problems need to be addressed post haste so as to ensure neither the functioning of the vehicle nor the safety of the passengers is compromised. Here are some of the signs to look out for of impending car exhaust repairs.
Your exhaust pipe is emitting strange noises
The component that allows your car exhaust to run inaudibly is the silencer. However, this auto part is located the furthest away from the engine, hence, it is prone to staying relatively cold. The cold surface then gives a chance for exhaust gases to condense on the surface of the silencer. This causes the formation of corrosive pools of acid right in the exhaust system. If you start hearing loud roaring noises coming from the exhaust pipe, chances are the silencer has become corroded over time.
Another sound to look out for in relation to the car's exhaust is hissing noises. Hissing typically indicates there is a crack that has developed right in the car exhaust's manifold and would need to be addressed by an auto mechanic post haste.
Lastly, rattling noses emanating from the car's exhaust will usually indicate that the system has moved out of place. This could also lead to vibrations as the exhaust system comes into contact with other components on the vehicle's undercarriage.
Your vehicle is experiencing decreased fuel efficiency
If you notice that you are spending more on fuel yet have not changed your regular driving routes, the cause could be a leak in your exhaust's manifold. Another car exhaust problem that could decrease your fuel efficiency include a malfunctioning oxygen sensor. Alternatively, you could find that the oxygen sensor is working fine but it ends up overcompensating for a leak in the exhaust system by burning more fuel to keep your vehicle running. The moment you realize that you are experiencing decreased fuel efficiency, it is best to take you vehicle for car servicing so that a professional auto mechanic can diagnose the cause and remedy the problem.
