  Q: How is the Fuel Rail Installed on a 3.7L Engine on Dodge Nitro?

  A:

  First, you should clean up the machined gas injector bores in the 3.7L engine's Intake Manifold before putting on the fuel rail. When you are putting in Fuel Injectors, add a little engine oil to the O-ring on each injector. Install the assembly onto the machined areas for the fuel injectors and guide the injectors through as you make sure the O-rings are intact. On each end, press the side of the fuel rail down so the fuel injectors are touching the cylinder head shoulder before moving to the other side. Attach each fuel rail mounting bolt and tighten them securely to Loctite 11 Nm (100 in lbs.). Here you should install the six Ignition Coils and then join the electrical connectors to the Throttle Body, then connect all fuel injectors and lock their connectors by sliding them down on all red locks. After that, connect the required vacuum/vapor lines to the throttle body and place the fuel rail latch's clip around the fuel rail. Install the air box to the throttle body and then thread the Air Duct to the air box. Attach the Battery Cable to the battery, crank the engine and make sure there is no leakage.

  Q: How to Remove the Fuel Rail on a 3.7L Engine on Dodge Nitro?

  A:

  Since the fuel system pressure stays on with the engine off, it's important to first let go of that pressure before removing the fuel rail on a 3.7L engine. If replacing the fuel rails, ensure you install them as an assembly-it's important not to split them where the tube is because there are no clamps; attempt to avoid bending or kinking the tube when removing it. First, get rid of the fuel tank filler tube cap and afterwards, break the negative Battery Cable's connection. Then, pull the Air Duct and air box from the Throttle Body and then separate the fuel line clip and fuel line at the fuel rail using a proper tool. Take away any vacuum or vapor links needed at the throttle body and then push the slider, depress the tab and pull the electrical connectors out of the six Fuel Injectors. Unplug the electricity at the sensors by the throttle body and then take out the six Ignition Coils. After finishing that, loosen and remove all four fuel rail mounting bolts. Slowly and carefully rock the fuel rail to the left and pull it a bit until the holes in the head are unclogged by the injectors. Then do the same for the right side. The last thing to do is remove the fuel rail with the injectors attached from the engine. If the removal of fuel injectors is needed, do it using the suitable procedure.
