Nissan Exhaust System Care: Ensuring Efficiency and Performance

Exhaust problems lead to increased pollution and decreased ​engine performance and fuel efficiency. If something is wrong with your Nissan exhaust, your Nissan dealership can fix the problem. ​We’d like you to know a few signs you need to visit us for an exhaust repair.

Blockage in the Exhaust

Combustion produces a range of dangerous and toxic gases. These gases are released when the cylinders open and are directed into the catalytic converter. The gases are converted to less harmful chemicals inside the converter and then pushed through the exhaust system to exit the tailpipe. Damage to the tailpipe or any blockage in the exhaust will cause serious engine problems.

If the gases can’t exit your vehicle, they flow back into your engine. They increase pressure in the engine, which can cause misfiring, stalling, or force your engine to shut down. If the exhaust is clogged, your engine might even shut down seconds after it starts as the accumulated gases prevent it from working. We’ll remove any blockage or replace damaged exhaust sections to fix this problem.

Black Exhaust Smoke

Black exhaust smoke is a sign your engine is dumping large quantities of unburnt fuel into the exhaust system. This can be caused by a blocked air filter, which restricts the amount of air in your engine. If the engine has insufficient air, much of the fuel in the fuel-air mixture won’t burn. This hot, unburnt fuel is dumped from the cylinders into the catalytic converter.

The converter won’t be able to convert all the unburnt fuel, and it may even suffer damage in the process. The unconverted fuel still contains dangerous chemicals and will exit the exhaust as a cloud of black smoke with a strong gas smell. Our technicians will replace your air filter, and air will flow into your engine normally again. In addition, we’ll check your converter and make any necessary repairs.

Reduced Fuel Efficiency

Your Nissan is known for its fuel economy. If you’re visiting the pump more often than you used to, you could have an exhaust problem. The most likely exhaust issue is a hole in the exhaust. The exhaust system is exposed to water and mud when you drive, and these substances can create rust over time. It’s also possible for hard objects like stones to be thrown up from the surface and puncture a hole in the pipe.

A leak in the exhaust pipe forces the engine to work harder, and this uses more fuel. Our technicians will examine your exhaust system and repair any damage. Once the exhaust system is airtight again, fuel efficiency will return to normal.

​Exhaust problems will worsen and can ​cause additional damage to your Nissan. Contact us today at Courtesy Nissan in Altoona, PA.
