- Screwdrivers (flathead and Phillips)
- Distributor wrench or adjustable wrench
- Timing light
- Basic hand tools (pliers, etc.)
- Shop manual for specific torque specs and details
Preparation Steps
- Disconnect the Battery: Always start by disconnecting the battery to prevent any electrical shorts or shocks.
- Remove Engine Covers and Components: Depending on your vehicle, you may need to remove certain components to access the distributor. This includes air intake ducts or the upper intake manifold.
- Make Note of the Current Timing: If you’re replacing the distributor, make a note of the timing before removing it. You can do this by using a timing light or marking the position of the current distributor.
Step-by-Step Installation
1. Remove the Old Distributor
- Locate and unbolt the distributor cap.
- Carefully lift it off to reveal the rotor.
- Mark the position of the rotor on the engine to guide reinstalling the new distributor.
- Unplug any wiring harnesses attached to the distributor.
- Remove the hold-down bolt and lift the old distributor out.
2. Install the New Distributor
- Align the new distributor with the mark you made earlier, ensuring the rotor is pointing to the same spot as the old distributor.
- Carefully lower it into place, ensuring it meshes correctly with the oil pump drive.
- Once in position, replace the hold-down bolt and tighten it with your torque wrench according to the specs in your shop manual.
3. Reassemble Everything
- Reconnect all wiring harnesses to the new distributor.
- Place the cap back on, ensuring it’s secure.
- Replace any components you had to remove for access.
4. Timing Your Engine
- Reconnect the battery.
- Use a timing light to check and set the timing as previously noted.
- Adjust as necessary for optimal engine performance.
Troubleshooting Tips
- If the engine won’t start: double-check that all connections are secure and that the rotor is aligned properly.
- For misfiring issues: ensure that your spark plug wires are connected in the correct order.
