  Q: How to Service and Repair an Intake Manifold on Chrysler 300M?

  A:

  To service the lower intake manifold, start with the fuel pressure release and empty the cooling system. Untwist the upper radiator hose from the outlet near the front of the manifold and afterwards, take out the upper intake manifold. After that, unplug the cables from the Fuel Injectors and Coolant Temperature Sensor and take off the heater and coolant bottle hoses attached to the rear of the intake manifold. Take out the fuel hose from the rail, disconnect the screw fastening the rail support bracket to the throttle body support bracket and unbolt and remove the Fuel Rail. Disconnect the fuel rail and its injectors, then take out the bolts connecting the lower intake to remove the intake manifold. Look for damage, cracks, blemished gasket and warped or distorted sections on the manifold; if any problems are noticed, you should replace it. Thoroughly clean where the seals go and check the gaskets for rips or cuts; replace them when needed. Raise the gaskets and the intake manifold into place on the cylinder head surfaces and then set the fuel rail with the injectors into position. Place the bolts onto the intake manifold and fasten them following the correct order, stopping when the torque reaches 28 Nm (250 in. lbs.). Bolt the end of the fuel rail support bracket screw to the throttle body support bracket, attach the fuel supply hose to the fuel rail and hook up the heater and coolant bottle supply hoses to the coolant tube at the rear of the intake manifold. After that, attach the electrical wirings to the fuel injectors and coolant temperature sensor, fit the upper intake manifold, reposition the radiator upper hose so it's connected to the coolant outlet on the front side of the lower manifold and finally fill the cooling system.

  Q: How to Maintain the Intake Manifold on Chrysler 300M?

  A:

  Before servicing the lower intake manifold, release the fuel system pressure and let out the coolant. Clear off the upper intake manifold, then take out the electrical connectors from the Fuel Injectors and Coolant Temperature Sensor. After that, disconnect the heater and coolant bottle supply hoses from the coolant tube at the rear of the intake manifold and then the fuel supply hose from the Fuel Rail. Unscrew the screw on the fuel rail support bracket that is connected to the throttle body support bracket and unbolt the fuel rail. After that, take out the fuel rail and injectors as a group. Unlock and remove the bolts connecting the lower intake and get rid of the intake manifold. Clean all areas to be sealed and make sure the gaskets are intact; change gaskets with tears or cuts. Mount the gaskets and intake manifold on the cylinder head, afterwards put the fuel rail with injectors in place. Mount the manifold bolts, secure them one at a time as stated in the sequence and stop when the torque reaches 28 Nm (250 in. lbs.). Screw in the fuel rail support bracket screw, link the fuel supply hose to the fuel rail and re-hook the heater and coolant bottle supply hoses. After that, reconnect the electrical parts to the fuel injectors and coolant sensor and install the upper intake manifold. After filling the cooling system, start the Asd Fuel System Test with the Drbiii scan tool to check for leaks in the fuel system. Leave the Asd relay energized for at least 7 minutes, unless the ignition switch is turned off or the Stop All Test is run.
