Then pull the fuel line from the clasp and then pull off the exhaust manifold heat cover. Then, with a socket wrench, unbolt and temporarily relocate the upstream oxygen sensor, lift the car and securely position it on jack stands. Undo the nuts securing the exhaust manifold brace, withdraw the brace and the nuts, then unfasten the nuts securing the exhaust manifold to the cylinder head; the nuts are to be replaced should they be used on this job. For installation clean mating surfaces on the cylinder head, manifold, and on the exhaust pipe using a scraper and solvent to make sure that they are flat and undamaged; if they are warped or damaged they may need to undergo some machining. The new gasket must be fitted on the cylinder head studs then the manifold applied on the cylinder head while tightening of the nuts is done from the center and outward to the standard torque. Join the exhaust pipe to the manifold/catalytic converter assembly and fasten its nuts with the appropriate measure of force.

Pontiac G6 Exhaust Manifold

The Exhaust Manifold in Pontiac G6 vehicles plays an important part of channelling hot gases away from the engine towards the exhaust system to promote the correct performance of the engine as well as lowering the toxic emissions. Located at different points based on the engine configuration, this usually made of either cast iron or stainless steel although there are performance replacement manifolds referred to as headers which are optimized for flow. Some variations in the models of the Pontiac G6 may exhibit change in the specification of the exhaust manifold where headers are used to increase exhaust velocity and minimize back pressure. This can greatly affect the engine performance especially in efficiency and power it produces as determined by this design difference. Also coatings which are usually wraps can help contain heat in the engine bay but also causes manifold wear early enough.

Each OEM Pontiac G6 Exhaust Manifold we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
