Installing an HEI distributor is a great way to improve the performance of your vehicle's ignition system. HEI stands for High Energy Ignition, which means it produces a hotter spark that can ignite the fuel mixture more efficiently. This can result in better fuel economy, more horsepower, and better throttle response. In this article, we will provide step-by-step instructions for installing an HEI distributor.
Tools and Materials
Before starting the installation, you'll need to gather the necessary tools and materials. Here's a list:
- HEI distributor
- Distributor cap
- Spark plug wires
- Ignition coil
- Wrench set
- Screwdriver set
- Spark plug gap tool
- Timing light
Step-by-Step Instructions
Now that you have everything you need, let's get started with the installation:
- Disconnect the negative battery cable to prevent any electrical shocks.
- Remove the old distributor, including the distributor cap and spark plug wires.
- If your vehicle has a hydraulic camshaft, you'll need to install an adjustable vacuum advance canister on the new distributor. This can be done by removing the existing vacuum advance canister and replacing it with the new one.
- Install the new distributor by aligning the rotor with the mark on the distributor housing that corresponds to the #1 cylinder's firing position. The rotor should be pointing towards the #1 cylinder's spark plug wire.
- Install the distributor clamp and bolt, but don't tighten it yet.
- Insert the new distributor cap onto the distributor and connect the spark plug wires to the cap. Make sure you connect them in the correct firing order.
- Install the new ignition coil onto the distributor. This can be done by removing the existing coil and replacing it with the new one.
- Attach the distributor's wiring harness to the ignition coil.
- Adjust the distributor's timing. This can be done by using a timing light and adjusting the distributor until the timing is correct.
- Finally, tighten the distributor clamp and bolt.
Tips and Warnings
Here are some additional tips and warnings to keep in mind:
- Make sure you install the new distributor correctly. If it's not aligned properly, your engine may not start or may run poorly.
- Be careful when working with the electrical components of your vehicle. Always disconnect the negative battery cable before starting work.
- Consult your vehicle's manual for the correct firing order and timing specifications.
- Use a spark plug gap tool to ensure the spark plugs are properly gapped before installing them.
- Always wear safety glasses when working on your vehicle.
Conclusion
Installing an HEI distributor is a straightforward process that can significantly improve your vehicle's performance. By following these step-by-step instructions and keeping these tips and warnings in mind, you can install an HEI distributor with confidence and enjoy the benefits of a hotter spark and improved ignition system.
