Installing a distributor in a 1998 dodge ram 1500 5.9 LT


Replacing Distributors: 1998 to 2005 models
  • Trace the spark plug wires to the distributor; it will be at the back of the engine block, in a cramped space.

  • Disconnect the negative battery cable to the distributor and unhook the air cleaner tube. Unscrew or unhook the clamps holding the distributor cap in place, and unscrew the Camshaft Position (CMP) sensor connector with a screwdriver.

  • Matchmark the distributor housing and the rotor for later realignment, as well as the distributor housing and the intake manifold. Unbolt the holding clamp and remove the distributor.

  • Set the engine at Top Dead Center (TDC) mark of the No. 1 cylinder compression stroke with a socket with breaker bar (long-handled ratchet).

  • Install the Ram distributor, replace the clamp and lightly tighten the bolt. The distributor part number is A1303801 from Parts Train, but numbers differ from different manufacturers. Order using the model, year and engine size.

  • Turn the distributor in its seating so the rotor lines up with the No. 1 cylinder mark on the Camshaft Position (CMP) sensor. Bolt the clamp bolt to 200 foot pounds (22.5 Nm).

  • Reattach the CMP sensor connector and use the screws or clamps to replace the distributor cap. Connect the air cleaner tube and the negative battery cable

I need firing order for my gmc sierra 1997. I need to change an 02 censor on the side of the # 1 cylinder. 350 rear wheel


You may not have thought of this but, your ignition system uses a distributor. The cap is labeled with the cylinder number that the wires go to. Look for number one and follow it to the number one spark plug. You just identified bank 1. Bank 2 will be the other side of the engine.
