Comprehensive Guide on Installing an Automotive Ignition Distributor: Step by Step Process for Optimal Performance

Whether you're an experienced mechanic or a beginner, installing an automotive ignition distributor is a task you can do yourself. This guide will take you through the process in a simple and easy-to-understand format. Let's dive in!

Tools and Materials Needed

  • Automotive ignition distributor
  • Socket set
  • Screwdriver
  • Feeler gauge
  • Marker
  • Wrench set

Step 1: Preparation

Before you start, make sure your engine is cool. Working on a hot engine can lead to injuries. Disconnect the battery to prevent any accidental sparks or electrical discharge.

Step 2: Remove the Old Distributor

Mark the spark plug wires to remember their order. Remove them gently from the distributor cap. Use your wrench to loosen and remove the distributor hold-down bolt and clamp. Carefully pull out the old distributor.

Step 3: Align the Engine to Top Dead Center (TDC)

Rotate the engine until the number one piston is at the top of its compression stroke, which aligns it to TDC. Check your car's manual to understand how to do this for your specific model.

Step 4: Install the New Distributor

Insert the new distributor into the engine, ensuring that the rotor aligns with the mark for the number one cylinder. This step may take a few tries, as the distributor shaft needs to mesh with the oil pump drive and the camshaft gear.

Step 5: Secure the Distributor

Once the distributor is properly seated, replace the hold-down clamp and bolt. Tighten the bolt just enough to hold the distributor but still allow for adjustment.

Step 6: Install the Distributor Cap

Install the new distributor cap and start connecting the spark plug wires. Make sure to follow the correct firing order, which can be found in your car's manual. Make sure each wire is firmly seated in the cap.

Step 7: Set the Ignition Timing

Reconnect the battery and start the engine. Using a timing light, adjust the distributor housing until the engine is timed correctly. This is usually indicated by a mark on the harmonic balancer. Tighten the distributor hold-down bolt fully.

Step 8: Double-Check Everything

Make sure all connections are secure and the distributor cap is firmly in place. Check the engine's running and listen for any unusual noises. Finally, test drive the car to make sure everything runs smoothly.


Installing an automotive ignition distributor may seem daunting, but with the right guide and tools, you can do it yourself. This not only saves you money, but also gives you the satisfaction of working on your own vehicle. Remember, safety first!
