Grand Cherokee 2WD V6-3.7L (2008)
Exhaust Manifold: Description and Operation
DESCRIPTION
The exhaust manifolds (1 and 2) are log style with a patented flow enhancing design to maximize performance. The exhaust manifolds are made of high
silicon molybdenum cast iron. A perforated core graphite exhaust manifold gasket is used to improve sealing to the cylinder head.
The exhaust manifolds are covered by a three layer laminated heat shield (1 and 3) for thermal protection and noise reduction. The heat shields (1 and 3)
are fastened with a torque prevailing nut that is backed off slightly to allow for the thermal expansion of the exhaust manifold.
