The Importance of Proper Exhaust System Functioning

The exhaust system is responsible for removing harmful gases and pollutants from the engine and releasing them into the atmosphere, in addition to treating these gases and pollutants via the aftertreatment system. If the exhaust is not functioning properly, these harmful substances can build up and cause damage to the engine, leading to decreased performance, increased fuel consumption, and even engine failure.

Additionally, a malfunctioning exhaust system can result in decreased fuel efficiency, which can cost diesel truck owners hundreds or even thousands of dollars in fuel expenses over time. It can also cause increased noise levels, which can be a nuisance for drivers and passengers alike.

Common Exhaust System Issues and Their Symptoms

There are several common exhaust system issues that can arise in diesel trucks. Here are some of the most common issues and their associated symptoms:

  • Exhaust Leaks - A leak in the exhaust system can cause a loud, hissing sound and a noticeable decrease in power and fuel efficiency. A common symptom of an exhaust leak is the smell of exhaust fumes inside the vehicle.
  • Selective Catalytic Reduction (SCR) Catalyst and Diesel Oxidation Catalyst (DOC) Failure - The SCR Catalyst and DOC are responsible for converting nitrogen oxides, carbon monoxide, and hydrocarbons into nitrogen, water, and carbon dioxide. A failure in either of these components can decrease fuel efficiency, produce a noticeable decrease in power, and have more noticeable effects like blue exhaust smoke.
  • Diesel Particulate Filter (DPF) Failure - A failure in the DPF can cause a decrease in fuel efficiency and a noticeable decrease in power. A common symptom of a DPF failure is a warning light on the dashboard.

Esteban provided hands down the best customer service. My uhaul vehicle broke down and he was unable to fix it, it needed a tow. Esteban ensured I was safe and in a good place with uhaul sending a tow before he left. He even went out of his way to get me water and snacks since I have been on the side of the road for 3 + hours. There are good people in this world and Esteban is one of them. Amazing service and an even better human being.
