![]() It’s now common for engines to also have a variable spark timing in an effort to provide the most power and the best fuel efficiency possible. And with technology improving rapidly in recent years, cars are now all equipped with variable valve timing systems. However, for the engine to run optimally, the spark doesn’t only need to happen-it needs to happen at the right time. Remember to always follow the manufacturer’s instructions and consult a professional if you’re not sure about something.If you work on cars a little, you already know that it’s the spark plugs’ job to light up the air/fuel mixture inside the combustion chambers. By following the steps outlined in this article on how to use a dial back timing light and using the tips provided, you can use a dial-back timing light to achieve optimal engine performance, fuel efficiency, and reduced risk of engine damage. ConclusionĪ dial-back timing light is a useful tool for ensuring accurate engine timing. Q: Can I use a dial-back timing light on a diesel engine?Ī: No, a dial-back timing light is not suitable for use on a diesel engine. Q: Can I use a dial-back timing light on any engine?Ī: Yes, a dial-back timing light can be used on any engine, as long as it has a distributor and ignition timing can be adjusted. Q: How often should I check my engine’s timing?Ī: It’s recommended to check your engine’s timing every 10,000 miles or during routine maintenance. A timing light ensures accurate timing and optimal engine performance. Q: Can I adjust the timing without a timing light?Ī: While it’s possible to adjust the timing without a timing light, it’s not recommended. Q: How do I know if my engine’s timing is off?Ī: If your engine’s timing is off, you may experience symptoms such as rough idle, decreased power and fuel economy, and engine knocking or pinging. Here are some frequently asked questions about the use of dial back timing lights – If you’re not sure about the timing specifications, consult the vehicle owner’s manual.Check the timing multiple times to ensure it’s accurate.Keep the timing light sensor away from moving parts to avoid damage.Set the advance to the manufacturer’s specifications.Use a timing light with a dial-back feature to adjust the timing accurately.Make sure the engine is at operating temperature before checking the timing.Using a dial-back timing light is easy, but here are a few tips that can help you get the best results: Repeat the process until the timing is accurate. Step 5: Recheck the TimingĪfter adjusting the timing, recheck it to ensure it’s within the specified range. Adjust the distributor until the timing marks align with the specified value. The strobe light will flash, and you should be able to see the timing marks. Step 4: Check the TimingĪim the timing light at the engine’s timing marks and pull the trigger. You can refer to the manufacturer’s specifications to determine the correct advance for your engine. Turn the distributor clockwise or counterclockwise to set the desired advance. The red lead should be connected to the positive terminal and the black lead to the negative terminal. Step 2: Connect the Timing LightĬonnect the timing light to the battery and the number one spark plug wire. Ensure the battery is fully charged, and the charging system is working correctly. Turn off any accessories that may affect the engine’s idle speed. Here’s a step-by-step guide to help you: Step 1: Prepare the Engineīefore you start, make sure the engine is at operating temperature and idling correctly. Using a dial-back timing light is not difficult. How to Use a Dial Back Timing Light: Step-by-Step Guide They have a built-in circuit that adjusts the strobe flash timing according to the advance you set, allowing you to check the timing accurately. You can adjust the timing by rotating the distributor until the timing marks align with the specified value.ĭial-back timing lights have a knob that allows you to set the desired advance. It works by flashing a strobe light at the engine’s timing marks, making it easy to see the position of the crankshaft.
