How do you use a timing light?

The timing light is connected to the ignition circuit and used to illuminate the timing marks on the engine's crankshaft pulley or flywheel, with the engine running. The apparent position of the marks, frozen by the stroboscopic effect, indicates the current timing of the spark in relation to piston position.

Will car start if timing is off?

A car's engine timing is the time between when the spark plugs fire and when the pistons begin moving. If your engine timing is off, your vehicle may run poorly or not at all. This can cause your engine to stall or run rough, and it may even cause other problems.

How do I adjust the timing on my car?

To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you'll advance the timing by rotating the distributor counterclockwise, and vice versa.

How to know the timing of a car?

Timing adjustments are measured in degrees. You will advance or move back your timing by a few degrees during this process. You can find these numbers on the engine’s crankshaft pulley or flywheel. It will be the guide to precise timing adjustment. By looking at that number, you can compare what you see to what manufacturer recommendations. And that number is different depending on car models, car makers. But it is not listed on the owner’s manual so you can check on the manufacturer’s websites or listings from professional mechanics.

What Is Timing?

Let’s get to know some more factors about timing in your car before jumping to using the tool. You see the timing in degrees that you can move forward or backward. It is performed by testing the exact timing of your car and matching it with your car’s manual. Accordingly, you adjust the timing back or forward until it matches your automobile’s manual.

How does a car engine work?

In detail, the engine works by using small explosions of gasoline to make pistons move up and down. That motion spins the engine which in turn rotates the gears and spins the wheels.

How does a timing light work?

Each time the distributor or coil pack fires through the wire to the spark plug, the timing gun senses the electrical charge and simultaneously fires a light pulse out the end of the gun.

What is a timing light?

A timing light is a tool that can check engine ignition timing coming from the distributor. It's got a plastic housing, often shaped like a laser gun from a '70s sci-fi movie. The pistol grip is thought to provide a better handle for precise aiming in tight quarters, but it's probably more likely people expect it to look ...

What is the red and black on a timing gun?

The red and black are positive and negative for the battery terminals to supply power and ground. The inductive clamp connects onto the No. 1 spark plug wire, and sometimes onto the spark plug itself. Some older timing gun designs are not inductive and instead feature a spring that connects the plug wire to the plug;

How to check timing on a crankshaft?

With the engine running and the timing light connected, press the trigger, and the light will pulse with a strobe effect to highlight what your timing is. You can see this measured in degrees.

Why is the timing light called the timing light?

Why does my engine make a ping sound?

Engine Knocking – Pre-ignition (or detonation) is the technical term for that ping or knocking sound caused by the fuel and air mixture in the cylinder igniting at the wrong time. If you've never heard it, it's a lot like a metal hammer on the inside of your engine, usually when accelerating or under load. This could be caused by using a lower-octane fuel than the engine requires, or an excessive amount of deposits in the fuel system. Knocking is a serious condition, so try a higher-octane gas with a fuel system cleaner, and check the timing. Newer engines have an antiknock sensor that feeds information back to the engine control computer when pre-ignition is detected, and the computer then adjusts timing accordingly.

How to loosen distributor bolt?

You can use a distributor wrench (usually 9/16 with a right-angle bend in the shaft) to loosen the hold-down bolt for the distributor. Depending on whether your distributor spins clockwise or counterclockwise, turn the distributor gently in one direction or another to advance or retard the spark, then tighten the hold-down bolt again.

Lastly, you take the signal wire and clamp ...

What does the timing light do when the engine is running?

When you pull the trigger of the timing light (with the engine running), each time the Number 1 plug fires, the timing light flashes a beam of light. Through a phenomenon known as the stroboscopic effect, a properly aimed timing light will indicate where the Number 1 piston is in its up-and-down travel when the spark fires.

How to tell if crankshaft pulley is TDC?

On some vehicles, the crankshaft pulley has a bunch of degree marks and numbers on it. The engine has a mark right next to the pulley that represents TDC. The strobing timing light "freezes" the motion of the pulley and allows you to see how many degrees before or after TDC the spark is firing. By manipulating the distributor cap (turning it slightly clockwise or counterclockwise), you can adjust that timing of the spark delivery. To make things more confusing: Sometimes the timing marks are found on the flywheel or even on the fan pulley. And sometimes the indicators are reversed. So just read your vehicle's manual and know what you're looking for before you start waving that light gun around!

What is an inductive timing light?

These inductive timing lights are able to detect the jolt of electricity each time the spark plug fires, similar to a doctor using a stethoscope to determine your body's pulse.

Why do you need timing lights?

Simply put, a timing light helps to fine tune when the spark fires from the spark plug and ignites your car's fuel. Properly adjusted timing, in turn, helps to make sure your engine works at peak power and efficiency.

How to tell if a piston is up or down?

Through a phenomenon known as the stroboscopic effect, a properly aimed timing light will indicate where the Number 1 piston is in its up-and-down travel when the spark fires. Representatively speaking, that is. Obviously, you don't see the actual piston's location. Instead, the timing of the spark is measured in terms of degrees. The degrees refer to how far the crankshaft has rotated relative to the Number 1 cylinder's piston at top dead center (TDC) of the compression stroke.

Where do you find timing specs?

How do you know what the proper timing specifications are? You can easily find that on your Vehicle Emission Control Information Label (located on the underside of the hood or along a fender well for vehicles built in the United States) or in a service manual specific to your vehicle.
