With all the exhaust your truck can put out, it needs to go somewhere. That’s why your truck’s exhaust system is so important.
The exhaust system redirects the exhaust gases, which can be toxic to humans in concentrated amounts, safely away from your truck’s cab. Typically, your truck will also include components designed to control the truck’s emissions by breaking down and negating its chemical makeup into more inert components.
The team at BoomTech knows how essential your exhaust system is to maintaining a comfortable, smooth, and safe ride. That’s why when you schedule an in-shop consultation or mobile service, our technicians will go over every inch of your exhaust system to ensure it’s not only operating at peak efficiency but that it’s both properly sealed and that all emissions control components are working as they should. You can rest assured that we use only the best tools and parts and treat your diesel truck with the respect it deserves.
To assist you in seeing the signs of issues with your exhaust system and its components, here are some common problems that can affect said systems.
Common Exhaust System Problems
Malfunctioning SCR Catalyst
One of several emissions control components your engine uses, the Selective Catalytic Reduction (SCR) Catalyst is used to convert nitrogen oxides in your exhaust into more benign nitrogen and water; these are further separated into their basic compounds. Signs that your SCR Catalyst is having issues are very visual; they can take the form of blue exhaust smoke or warning lights on your dashboard. Your SCR catalyst is closely linked with your EGR system, which conversely means that if the latter suffers and has issues like a valve failure then the former can end up with contamination build-up. This contamination can also occur if your oil cooler suffers a failure as well.
Malfunctioning Diesel Oxidation Catalyst
In a similar manner to how your SCR catalyst treats nitrogen oxides, your Diesel Oxidation Catalyst (DOC) treats your exhaust’s carbon monoxide and hydrocarbon outputs into harmless carbon dioxide and water. Warnings of DOC malfunction are similar to the SCR in the form of the exhaust system and check engine warning lights. If your truck is left idle for extended lengths of time or if the exhaust temperature is lower than normal, then carbon can begin building in the DOC’s inner walls and requires necessary cleaning to remove this build-up.
