How to Check Car Engine Points
What are Engine Points?
Engine points are a mechanical contact that opens and closes the electrical circuit to the ignition coil. This causes the coil to generate a spark at the spark plugs, which ignites the air-fuel mixture in the cylinders.
Points are typically made of tungsten or platinum, and they are mounted on a base plate that is attached to the distributor. The points are opened and closed by a cam lobe on the distributor shaft.
Why Check Engine Points?
Points can wear out over time, which can cause the ignition timing to be off. This can lead to a loss of power, fuel economy, and performance.
Checking the points is a simple and inexpensive way to ensure that your engine is running at its best.
How to Check Engine Points
To check the engine points, you will need the following tools:
- Feeler gauge
- Wrench
- Spark plug wrench
Follow these steps to check the engine points:
- Disconnect the negative battery terminal.
- Remove the distributor cap.
- Locate the points. They will be located on the base plate of the distributor.
- Insert the feeler gauge between the points.
- The gap should be set to the manufacturer’s specifications. This information can be found in your vehicle’s repair manual.
- If the gap is not correct, loosen the screws that hold the base plate in place and adjust the gap.
- Tighten the screws and recheck the gap.
- Repeat steps 2-7 for the other set of points.
- Reinstall the distributor cap and connect the negative battery terminal.
Tips
- If the points are badly worn, they will need to be replaced.
- It is a good idea to check the points every 6,000 to 12,000 miles.
- If you are not comfortable checking the points yourself, you can take your vehicle to a mechanic.
Conclusion
Checking the engine points is a simple and inexpensive way to ensure that your engine is running at its best. By following these steps, you can keep your engine running smoothly and efficiently.
