Heavy-duty trucks are built for longevity and durability, but they occasionally show signs of wear. Exhaust systems are subject to enormous strain, but it can be difficult for drivers to know when things have gone wrong. Here are a few of the most common truck exhaust problems and some tips on handling them.
Trucks, especially heavy-duty models, sound louder if there`s an exhaust system problem. Drivers may notice an increase in noise when starting or accelerating, and many of these sounds are created by leaks in exhaust manifold gaskets. Rattling sounds are often connected to exhaust issues, but these noises have numerous sources—so it`s best to have the truck examined by a professional who will have big truck parts for you.
Loss of Power During Acceleration
Exhaust performance (or the lack of it) is at the root of many engine problems. If your truck doesn`t speed up as quickly as it once did, or if it loses power suddenly, an exhaust leak may be to blame. These leaks can be tough for drivers to find, which is why it`s best to have them checked out by experts.
Lower Fuel Mileage
Numerous factors, including exhaust problems, may cause a truck`s fuel economy to decline. Power decreases lead to fuel buildup in the exhaust system. When the engine doesn`t get the power it needs, it works harder and uses more fuel.
Exhaust functions significantly affect fuel economy. If your truck is running rough and uses more fuel, have the exhaust system checked.
Some exhaust problems have a smell all their own. For instance, a malfunctioning DPF emits a rotten-egg odor, while burning smells may indicate head gasket deterioration.
Inside the cab, you should never smell fuel—and if you do, there`s a problem with the exhaust pipes. If there`s an exhaust smell inside the truck, there`s likely a carbon monoxide leak. Odd smells are often the first sign of an issue, and they should be investigated as soon as possible.
Engine Warning Lights
A truck`s check engine light may come on for several reasons, some of which are more worrisome than others. Exhaust system issues are a common reason for warning lights to come on, and when it happens, it`s best to schedule service right away.
What Happens If Exhaust Leaks Aren`t Fixed?
A truck`s exhaust system routes emissions away from the cab. If there are issues, however, fumes may enter.
· Minor exhaust leaks decrease fuel efficiency and increase costs.
· Larger leaks may lead to engine overheating, which increases the risk of mechanical failure.
Neglecting exhaust repairs shortens the lifespan of a truck`s engine. If you`re looking for ways to stay on the road, schedule regular exhaust system maintenance and get repairs when needed.
Don`t Delay—Solve Exhaust System Problems Today
The exhaust system is one of a truck`s most vital components. It regulates emissions, protects the engine from harmful impurities, and keeps toxic gases out of the passenger compartment.
Drivers shouldn`t delay repairs if their trucks have problems like exhaust leaks, broken mufflers, bent pipes, and leaking gaskets. Exhaust systems consist of numerous interconnected parts, all of which must work properly for optimal function. By looking for these warning signs and resolving issues immediately, you can protect your health and your truck.
