      Timing Devices

      A vehicle's timing system is important to the performance of the engine. When a timing system isn't running properly, an engine could have retarded engine timing or fail all together. There are a number of parts that are key to your vehicle's timing. Keep your entire timing system running smoothly with new timing belts, chains, and gears from Sears. All of these internal engine parts can wear from regular use. These parts are also all best installed as a set rather than individually. For installing these and all of your car parts, make sure you check out a wide selection of nuts and bolts, as well.

      Ignition and timing systems get your engine in sync

      There are two kinds of timing that take place in your engine: cam timing and ignition timing. Cam timing has to do with a number of components working together in your car's engine. A vehicle owner can generally tell if cam timing is working. If cam timing were not working, the engine would be running poorly or failing all together. Ignition timing, on the other hand, can be affected by a number of causes.

      Ignition timing can be thrown off by a number of factors. The system of ignition in your vehicle has to coordinate with the rest of your engine. The fuel needs to be ignited at the right time so that expanding gases will create the maximum impact. If the timing of the ignition is not correct, gas use and emissions can increase. When the mixture of air and fuel in the cylinder burns, the temperature rises. Fuel is then converted into gas. This increases the pressure in the cylinder and forces down the pistons. To get the most power from the engine, pressure in the cylinder needs to be maximized during the power stroke. This will also create the best engine efficiency and better mileage. The timing of the spark is what makes this possible.

      Timing can vary from engine to engine. Consult your vehicle's service manual for the best advice about how to correct your vehicle's engine timing. Many new engines can adjust the timing on their own or timing can also be adjusted with a timing light.

      To adjust timing with a timing light, follow instructions to wire the light. Point the light at the main pulley that is associated with the crankshaft. Time the engine to zero degrees advance. Point the light at the mark on the pulley. It will appear to flash. Loosen the distributor and turn it slightly. That mark will move left or right. If you turn it too much, the mark will leave all together. The engine can also be turned off this way. On most crank pulleys, there will also be another mark. This should be 3-5 degrees before the top dead center. This is the mark to aim for. Turn the distributor until the mark flashes at the correct spot every time. Once set, tighten the distributor.

      To find timing lights and other high-quality car parts, shop Sears. You'll find parts from manufacturers like Equus, Dow, Ferret and Sierra. Also check out other high quality car parts from Sears, like camshafts, internal valves, and external timing chains.
