You are watching: 2001 dodge ram 1500 distributor cap
This article uses to the Dodge lamb 1500 (1994-2001).
The distributor cap and also rotor ~ above the 2nd generation Dodge ram 1500 are an essential components of the ignition system. Voltage from the ignition coil is sent directly to the spinning rotor inside of the distributor, which climate transfers the voltage to each contact suggest of the distributor cap. The electric charge is then sent out from the distributor cap to every of the engine"s spark plugs via spark plugs wires at the an exact time for combustion to occur. End time, the call points on the distributor cap and rotor deserve to wear, have extreme carbon buildup, or even break. Typically, these concerns will reason reduced engine performance; however, in major cases, a fail distributor lid or rotor will prevent your engine from to run at all. Maximize your engine"s effectiveness by installing new a distributor cap and also rotor.

Step 1 – eliminate airbox assembly
The distributor is situated underneath the airbox assembly and also behind the accelerator body. To gain accessibility to the distributor, the airbox assembly needs to it is in removed.First, eliminate the wait intake pipe off of the airbox. Applying gentle force, slide the tube away from the airbox and also position it out of the way.Remove the rubber breather hose. Depending on engine model, this hose might be situated on the left or ideal side that the airbox. This tube just slides on and off that the airbox nipple.On the underside that the airbox, loosen the water tap clamp securing the airbox come the throttle body.With all fittings disconnected, lift increase on the airbox assembly and also remove that from the engine bay.
Step 2 – Label and remove spark plug wires
With the airbox assembly removed, the distributor is now accessible.
It is a good idea to map the spark plug wires from every cylinder ago to the distributor cap when labeling the wires.
Step 3 – replace distributor cap and rotor
Now that the spark plug wires and also coil cable are gotten rid of from the distribitor cap, the cap deserve to be eliminated from the distributor.Using a a 7mm wrench, socket & ratchet, or Phillips screwdriver, loosen the 2 distributor cap fasteners.

Next, install the brand-new rotor in the distributor. As previously mentioned, over there is a groove in the distributor tower to ensure correct placing of the rotor.
Install the new distributor cap onto the distributor. Keep in mind that among the fastener mounts in the cap is square, if the various other is rounded to stop the lid from being erroneously installed. Additionally, the distributor lid should have a #1 stamped on it to suggest the place of the lid which should, relying on engine configuration, challenge towards the 7 or 9 o"clock position when installed (See number 5 because that the number "1" stamped into the cap). Be particular that the cap is appropriately seated in place on the distributor and tighten the fasteners. A misaligned cap will interfere with the transfer of electrical voltage indigenous the rotor to the distributor cap and also prevent proper combustion native occurring.
It is always a good idea to compare the new distributor cap and also rotor to the old components to certain your have the correct parts. If either component is incorrect, your truck will likely not operation for absence of spark being delivered to the engine.
Step 4 – Reinstall spark plug wires and start truckAfter the brand-new cap and rotor have been installed, reattach the spark plug wires and also coil cable to the distributor cap. The labeling of the wires completed in action 2 will come in handy and allow you to reinstall the wires in the correct place on the cap. Push down steady on each wire boot till an audible "click" is heard to ensure the wires are appropriately seated top top the cap.With all wires properly in location on the cap, begin the truck and also check the the engine is running properly. If the engine is misfiring or backfiring, shut the van off and also check that the spark plug wires are set up in their correct positions.
Step 5 – Reinstall airbox assembly
If the truck checks out okay after a test start, continue with reinstalling the airbox assembly. Be sure the base of the airbox is seated properly over the throttle body prior to tightening the water tap clamp. Download the intake tube and rubber breather hose.
