Exhaust manifold is a part of the exhaust system. It serves to collect and withdraw exhaust gases from the cylinder head. As the car has several cylinders in the vehicle, the exhaust manifold must be located in such a way to withdraw exhaust gases in the optimal way. It is necessary to prevent the situation when exhaust flows interfere with each other. This is achieved by adjusting the firing order. As a rule, the different flows of exhaust gases are separated and join each other rather late. Then they are sent to the exhaust pipe.

Exhaust manifolds are made of cast iron and steel. Cast iron manifold withstands higher temperatures, but the steel manifold is much easier. In modern cars both types of manifold are used. Generally, exhaust manifolds break down because of wear. In the course of time high temperatures and corrosion result in cracks and holes. Small holes can be welded up. If it is a serious damage, replacement is required. It is quite easy to dismantle the old exhaust manifold. First you need to remove sheet metal cover. Then unscrew the nuts on the exhaust manifold.

To install car parts is a certain difficulty. As the exhaust manifold is located close to the cylinder blocks, it must be polished. Only a specialist can do this work. It requires a high degree of accuracy and special tools. In any case, after installation check the tightness.
