You can Select Your Vehicle to check if 68036151AK fits your vehicle.

Start by raising the vehicle and securing it on jackstands. If applicable, spray penetrating oil on nuts and bolts for easier loosening. For 2.4L engines (2014 and earlier), remove the oxygen sensor and rear portion of the exhaust system, then detach the converter from the exhaust manifold. For 2.7L engines, remove the front exhaust manifold/catalytic converter by disconnecting oxygen sensors and other components. For rear exhaust manifold/catalytic converter, remove the engine cover, splash shield, crossunder pipe, and oxygen sensors. For 3.5L engines, remove the front and rear exhaust manifold/catalytic converters by disconnecting oxygen sensors and other fasteners. For 3.6L engines, remove the rear catalytic converter by loosening clamps and fasteners, then guide the converter out from the bottom. Before installing the converter, use anti-seize compound on threads and tighten the fasteners securely. Installation is the reverse of removal for all models.

If removing the rear exhaust manifold, detach the EGR pipe from the top of the manifold. If removing the front manifold, also remove the air filter housing and the engine oil dipstick tube.

Remove the mounting bolts and detach the manifold from the cylinder head, ensuring to spray penetrating oil on the bolts beforehand.

Clean the mating surfaces to eliminate old gasket material and inspect the manifold for distortion and cracks, checking for warpage with a precision straightedge.

Remove the exhaust manifold upper heat shield mounting bolts and the heat shields, then detach the manifold from the cylinder head, applying penetrating lubricant to the bolts and threads beforehand.

Raise the vehicle and remove the engine under cover, then detach the catalytic converter-to-exhaust manifold nuts, discarding the old gasket.

Use anti-seize compound on threads and tighten the fasteners securely.

Begin by removing the engine cover and disconnecting the negative battery terminal.

Apply penetrating oil to the exhaust manifold fasteners and let it soak.

Remove the intake manifold fasteners, lower the vehicle, and remove the throttle body and intake manifold as a single assembly, detaching the throttle body and gasket from the intake manifold after placing the unit on the bench.

Detach the manifold by removing the mounting bolts, applying penetrating lubricant beforehand.

Yes, due to a Federally mandated extended warranty which covers emissions-related components such as the catalytic converter, it is recommended to check with a dealer service department before replacing the converter at your own expense.
