  Q: How to Install a Fuel Injector in a 2.7L Engine on Dodge Magnum?

  A:

  Before you start the 2.7L fuel injector installation, lightly brush clean engine oil on each of the fuel injector O-rings. After that, add the retaining clips to the fuel injectors and use them to guide the injectors into the Fuel Rail as the clips are settled. Lay the fuel rail atop the cylinder head and press it down into place and then tighten the mounting bolts to 11 Nm (100 in. lbs.) torque. You should join the supply tube fittings on the rear end of the Intake Manifold and join the electrical connectors to the fuel injectors. After that, fit the intake manifold plenum and connect the negative cable directly to the battery. Relative to everything mentioned so far, the fuel system can be pressurized using the scan tool to locate any possible leaks.

  Q: How to Effectively Service and Repair Fuel Injectors on Dodge Magnum?

  A:

  The first step in servicing or repairing fuel injectors is to make sure you release the fuel system pressure since it is always under pressure. Remove the Intake Manifold plenum by first taking out the negative Battery Cable and covering the intake manifold so dirt doesn't find its way in. Detach the fuel supply tube's quick connect fittings at the back of the intake manifold and if the injector connectors do not have labels, write down which one is for each cylinder. Remove the connectors from the fuel injectors and then take out their mounting bolts on the Fuel Rail, so you can lift the rail off the cylinder. Take off the retaining clips and pull out the injectors; examine the O-rings to see if they're damaged and replace them if so, then install new injector clips as well. After you lube the O-rings slightly with clean oil, set the retaining clips on the injectors and press them onto the fuel injector rail until the clips attach properly. Situate the fuel rail onto the cylinder head and press it in, holding it while you tighten the mounting bolts to 11 Nm (100 in. lbs.). Link the quick connect fittings for the fuel supply tube to the fuel injectors, connect the electrical cables to the injectors, place the intake manifold plenum in its spot and link the negative battery cable again. When you're done, use the scan tool to pressurize the fuel system and watch for leakage.
