Description

The Exhaust Manifold (part number: 3979211) is a component of a truck’s exhaust system that collects and directs exhaust gases from the engine’s cylinders into the exhaust pipes. It is usually made of cast iron or stainless steel and has several ports corresponding to each cylinder in the engine. The manifold is bolted to the engine block and sealed with gaskets to prevent leaks. Its primary function is to channel exhaust gases away from the engine and into the catalytic converter, where they are treated before being released into the atmosphere. A damaged or worn-out manifold can cause poor performance, reduced fuel efficiency, increased emissions, and even engine damage due to overheating. Regular inspection and maintenance of this critical component are recommended to ensure optimal performance and longevity of your truck’s exhaust system.
