Setting the ignition points on a car is a crucial maintenance task that can enhance engine performance and fuel efficiency. In this guide, we will delve into the process of setting the points, the importance of this maintenance step, and some practical tips to help you get it right.
What Are Ignition Points?
Ignition points are part of the ignition system in older vehicles, specifically those with a contact breaker style ignition system. They work by opening and closing to allow the electrical current to flow and ignite the fuel-air mixture in the engine's cylinders. When these points are set correctly, they ensure that the ignition timing is accurate, which is essential for optimal engine performance.
Why Is It Important to Set the Points Correctly?
When the points are set too wide or too narrow, it can lead to several problems, including:
- Poor Engine Performance: If the timing is off, the engine may run rough, stall, or have trouble starting.
- Increased Fuel Consumption: An incorrect setting can lead to inefficient combustion, which wastes fuel.
- Higher Emissions: When the engine doesn’t run efficiently, it produces more harmful emissions.
How to Set the Points on a Car
What You’ll Need:
- A feeler gauge
- A socket set
- A screwdriver
- A timing light (optional, but recommended for precision)
Step-by-Step Instructions:
-
Locate the Points:
- The ignition points are typically located in the distributor cap. Remove the cap to access the points.
-
Turn the Engine:
- Use a socket to turn the engine to the appropriate position (usually at the top dead center of the number one cylinder).
-
Check the Points Gap:
- Insert the feeler gauge between the points. The gap should typically be between 0.016 to 0.020 inches, but refer to your vehicle's manual for the exact specifications.
-
Adjust the Points:
- If the gap is not within specification, loosen the points’ retaining screw and adjust the gap by either pushing or pulling on the movable point. Retighten the screw once adjusted.
-
Double-Check the Gap:
- Reinsert the feeler gauge to ensure the gap is correct.
-
Reassemble:
- Replace the distributor cap and any other components that were removed.
-
Test the Ignition:
- Start the engine and observe its performance. For precise timing, you can use a timing light to adjust the ignition timing if needed.
Additional Considerations:
- Regular Maintenance: It’s good practice to check the points at regular intervals, particularly if your car is older and relies on this system.
- Upgrade Options: Consider upgrading to an electronic ignition system, which eliminates the need for points adjustment and provides more reliable ignition timing.
Troubleshooting Common Issues:
If your car still has performance issues after adjusting the points, consider the following:
- Worn or Pitted Points: If the points are pitted or worn down, they may need to be replaced.
- Dirt or Corrosion: Clean the points with a fine emery cloth to ensure they are making proper contact.
- Faulty Components: Check other ignition components, such as the coil and spark plugs, for any signs of wear or damage.
Conclusion
Setting the points on your car may seem daunting at first, but with the right tools and a bit of patience, it’s a task you can manage. Properly set points can improve your vehicle's performance, fuel efficiency, and reduce emissions. Regular maintenance and check-ups will ensure your car continues running smoothly for years to come.
Remember, if you're unsure at any stage, consult your vehicle's manual or seek professional assistance to avoid potential damage. Happy wrenching!
