The distributor cap and rotor top top the dodge Ram are wear items that occasionally need replacing. No just do these components wear from continuous use, however they room made the plastic the can come to be brittle and fail with age. V the cap and rotor being such essential parts of the ignition system, continual maintenance is recommended to store your ram truck to run at it"s best.
You are watching: Where is the distributor cap located
This article uses to the Dodge ram 1500 (1994-2001).
The distributor cap and rotor top top the second generation Dodge ram 1500 are an essential components the the ignition system. Voltage indigenous the ignition coil is sent straight to the turn rotor within of the distributor, which then transfers the voltage to every contact suggest of the distributor cap. The electrical charge is then sent from the distributor lid to every of the engine"s spark plugs via spark plugs wires in ~ the an accurate time for combustion to occur. End time, the contact points top top the distributor cap and rotor have the right to wear, have extreme carbon buildup, or also break. Typically, these worries will cause reduced engine performance; however, in significant cases, a fail distributor lid or rotor will stop your engine from to run at all. Maximize her engine"s performance by installing new a distributor cap and rotor.

Step 1 – eliminate airbox assembly
The distributor is located underneath the airbox assembly and also behind the accelerator body. Come gain access to the distributor, the airbox assembly requirements to be removed.First, remove the air intake tube off the the airbox. Using gentle force, on slide the pipe away indigenous the airbox and also position it the end of the way.Remove the rubber breather hose. Depending on engine model, this hose may be situated on the left or right side the the airbox. This tube simply slides on and off of the airbox nipple.On the underside of the airbox, ease the water tap clamp securing the airbox to the accelerator body.With every fittings disconnected, lift increase on the airbox assembly and remove it from the engine bay.
Step 2 – Label and also remove spark plug wires
With the airbox assembly removed, the distributor is currently accessible.
It is a great idea to trace the spark plug wires from every cylinder ago to the distributor cap as soon as labeling the wires.
Step 3 – replace distributor cap and also rotor
Now that the spark plug wires and coil cable are removed from the distribitor cap, the cap can be removed from the distributor.Using a a 7mm wrench, socket & ratchet, or Phillips screwdriver, ease the two distributor cap fasteners. The fasteners are located at the 3 & 9 o"clock location at the basic of the cap. After ~ loosening the fasteners, remove the distributor lid by just lifting the up. A little bit of maneuvering might be forced to remove the cap from the engine bay together the to the right is a little bit tight at the back of the engine.After removed the cap, the rotor can be gotten rid of by simply providing it for sure tug upwards. Execute not worry about marking that orientation as the distributor shaft has a small groove to permit the rotor to just be mounted one way.
Next, install the new rotor in the distributor. As formerly mentioned, there is a groove in the distributor pillar to certain correct positioning of the rotor.
Install the new distributor lid onto the distributor. Note that among the fastener mounts in the lid is square, when the various other is rounded to protect against the cap from being incorrectly installed. Additionally, the distributor cap should have actually a #1 stamped on the to show the place of the lid which should, depending upon engine configuration, challenge towards the 7 or 9 o"clock place when mounted (See number 5 because that the number "1" stamped into the cap). Be certain that the cap is appropriately seated in location on the distributor and tighten the fasteners. A misaligned cap will certainly interfere through the move of electric voltage from the rotor to the distributor cap and also prevent ideal combustion from occurring.
It is constantly a an excellent idea to to compare the new distributor cap and rotor to the old contents to ensure your have the exactly parts. If either component is incorrect, her truck will most likely not run for absence of spark being delivered to the engine.
Step 4 – Reinstall spark plug wires and start truckAfter the brand-new cap and also rotor have been installed, reattach the spark plug wires and also coil cable to the distributor cap. The labeling the the wires perfect in action 2 will certainly come in comfortable and allow you to reinstall the wires in the correct position on the cap. Press down firmly on each wire boot until an audible "click" is heard come ensure the wires are appropriately seated on the cap.With every wires appropriately in place on the cap, start the truck and check the the engine is to run properly. If the engine is misfiring or backfiring, close up door the truck off and check that the spark plug wires are set up in your correct positions.
Step 5 – Reinstall airbox assembly
If the truck checks out it s okay after a test start, continue with reinstalling the airbox assembly. Be certain the base of the airbox is seated appropriately over the throttle body prior to tightening the hose clamp. Download the entry tube and rubber breather hose.
