Mopar 4891832AB Pump-Air

Disconnect the negative battery cable from the remote ground terminal or battery. Remove the engine cover. The air injection pump is located behind the left end of the engine, above the rear portion of the transaxle case. Remove the Powertrain Control Module (PCM) and the PCM mounting bracket. Detach the tubes from the air pump by squeezing the collars of the quick-connect fittings. Raise the vehicle and support it securely on jackstands. Remove the bolt securing the air pump relay to the pump and reposition the heat shield. Lower the vehicle and remove the heat shield upper mounting bolt. Detach the shield. Disconnect the electrical connector from the air pump, remove the three mounting bolts, and detach the air pump from its bracket. Installation is the reverse of the removal procedure. Disconnect the air hose from the Secondary Air Injection Check Valve. Remove the Secondary Air Injection Check Valve mounting bolts and detach the valve from the exhaust manifold pipe. Clean the exhaust manifold pipe flange and the Secondary Air Injection Check Valve flange. Installation is the reverse of removal. Be sure to use a new gasket and tighten the bolts to the torque.

2015 and later models are equipped with either a mechanical or electric brake vacuum pump. The mechanical pump is driven by the rear end of the camshaft and mounted on the left end of the cylinder head on 2.4L engines, and the electric pump on 3.6L engines is located at the left side of the engine and secured to a bracket by two mounting bolts. Disconnect the cable from the negative battery terminal. Be careful not to damage the plastic vacuum pump hose connector fitting. Also, oil may leak from the pump so be sure to have plenty of rags ready to soak up spills. Remove the engine cover, then disconnect the quick-connect hose fitting from the pump. Remove the vacuum pump mounting bolts, then carefully separate the pump from the cylinder head. Discard the old O-ring seals. Remove the retaining screw and separate the plastic connector piece from the pump. Check and replace the O-ring on the fitting, if necessary.
