GMC, exhaust manifold replacement in Zevulun.
Such signs as a loud and unusual engine noise or an exhaust smell inside the car may indicate a failure of the exhaust manifold. The procedure for removing the manifold can be as follows: removing the splash shield from under the engine, removing the electrical connectors of the oxygen sensor, unscrewing the exhaust pipe from the manifold and the heat shield. Next, the manifold attachments and the manifold itself are removed. The installation of the new manifold is carried out in the reverse order.
