Q: How to Service and Repair an Intake Manifold on 2001 Dodge Stratus?
A: Remove the intake manifold by first unplugging the negative battery cable. Take off the throttle body air inlet hose and air cleaner housing assembly, next the throttle cable shield and pull out the throttle and speed control cables from the throttle arm and bracket. Following this, take out the throttle cable bracket and pull the connectors from the MAP Sensor, TPS, IAC Motor and MTV. Get rid of the Vapor Purge hose, Brake Booster hose, Speed Control Servo and Positive Crankcase Ventilation (PCV) hose and remove the EGR upper tube. Check under the intake manifold for signs of immobilization by first undoing the fastener on the throttle body support bracket, removing the bolts from the manifold, then checking the top manifold for damage. For the lower part of the intake manifold, open the fuel system, then remove the upper intake. Unplug the electrical connectors off the fuel injectors, disconnect the fuel supply hose from the fuel rail and remove the screw joining the fuel rail support bracket to the throttle body support bracket. After detaching the fuel rail through its bolts, pull them out with the injectors in one assembly, then undo the manifold bolts from beneath to remove the base of the manifold, inspecting it for any harm. As you install the upper intake manifold, clean and examine the sealing areas, make certain gaskets are not damaged and put the upper manifold over the lower manifold. Put in the manifold attaching bolts and tighten them together in the following order: 12 Nm (105 in. lbs.). After that, secure the upper fastener on the throttle body support bracket. Add the EGR upper tube in place, plug in the MAP Sensor, TPS, IAC Motor, MTV, PCV, brake booster and both vapor purge hoses. Add the throttle cable bracket, attach the speed and throttle cables to the bracket and throttle handle, replace the shield over the throttle cable and fit the throttle body air inlet hose to the air cleaner housing assembly. At last, plug in the negative battery cable. For the lower intake manifold, wipe and evaluate the seals at the head and manifold and ensure the gaskets aren't damaged, then fit the manifold on the corresponding surfaces on the cylinder head. To make sure the upper intake manifold is easy to assemble, add a bolt about 2 - 3 turns into the last hole on the intake's side. After attaching the fuel rail with its injectors, put the connecting bolts into the manifold and tighten them in order to 12 Nm (105 in. lbs.); be sure to remove the bolt you used for alignment. Carefully connect the fuel injector electrical connections so that each fuel injector sits properly so as not to interfere with the upper intake manifold, install the fuel rail support bracket screw securing both support brackets, connect the fuel supply hose to the fuel rail and then attach the upper intake manifold.
