2003 Mercury Marauder Intake Manifold Parts Questions & Experts Answers

• Q: How to service and repair the lower intake manifold on 2003 Mercury Marauder?

  A: Service and repair of the lower intake manifold requires draining of engine cooling fluid as the first step. The service requires removal of upper intake manifold and disconnection of fuel line spring lock coupling and Engine Coolant Temperature sensor electrical connectors and coolant hoses. The first step involves removing the accessory drive belt and the crossover tube before undeterring the generator support bracket bolts and generator unit. Following the removal of electrical connector and vacuum hose from the fuel pressure sensor you should separately detach the wiring harness from four fuel injection supply manifold studs. Separate the eight fuel injector electrical connectors then take out the ten bolts in specified order before slightly lifting the lower intake manifold to unplug the fuel charging wiring harness from its rear position. Thoroughly inspect the areas where gaskets disconnect while you eliminate the intake manifold gaskets. To install the new lower intake manifold gaskets first inspect them before putting them into place. The eight fuel injector electrical connectors should be reconnected while the intake manifold fasteners receive specified sequential tightening before attaching the gas hose to the lower intake manifold rear. Connect the eight fuel injector electrical connectors before securing the fuel charging wiring at its four hookups on the fuel injection supply manifold. First connect the electrical part and vacuum tubing to the fuel pressure sensor before you put on the generator and its bolts followed by generator support bracket with four bolts installed. You should install the crossover tube as a final step in the process while checking and potentially replacing any O-ring seals if required. After that you will add the accessory drive belt. The procedure continues with reconnecting coolant hoses followed by electrical connectors and concluding with the wiring harness retainer and ECT sensor electrical connectors and coolant hoses. When completing the installation procedure connect the fuel hose spring lock coupling along with the upper intake manifold before executing the engine cooling system filling process and subsequent bleeding procedure.
