Start and run the engine until it reaches its normal operating temperature.Make sure all spark plugs are in good condition and properly gapped.Make sure the timing mark and pointer are clean and clearly visible. The timing mark and pointer are usually located on the crankshaft pulley or vibration damper (on the front of the engine) or on the flywheel (between the engine and transmission). Locate the timing mark and reference pointer.The label is typically located on the underside of the hood, on a fender well or valve cover, or near the hood latch.Īs a minimum, make the following preparations before timing: The Vehicle Emission Control Label is located under the hood in the engine compartment.
#USING A TIMING LIGHT MANUAL#
Refer to the Vehicle Emission Control Label or service manual for timing procedures and specifications for your vehicle. Electrical connectors ENGINE PREPARATION BEFORE TIMINGĪlways prepare the engine for timing before performing a timing check.Refer to your vehicle’s service manual for proper connection of vacuum hoses, electrical wiring, and wiring harness connectors. Make a thorough check before starting any test procedure and fix any known mechanical problems before performing any test Loose or damaged hoses, wiring, or electrical connectors are often responsible for poor engine performance. Advance Control Knob – Selects timing light advance setting from 0° to 60°.
Press again to turn the timing light off. On/Off Switch – Press to turn timing light on.Operating controls for the SP62040 Timing Control Panel – Contains the controls necessary to operate the Timing Light.Rotates over approximately 90° to allow for easy illumination of timing marks in hard-to-reach locations. Swiveling Head – Contains the xenon bulb.Xenon Bulb – Used to illuminate timing marks for checking the timing.Consult your vehicle’s service manual for procedures and specifications before attempting to time vehicles with DIS systems. Your timing light is designed for use on all 12- volt negative ground vehicles equipped with conventional breaker point, and electronic ignition systems or with DIS (distributorless ignition systems). Adjustments are made and parts are replaced ONLY if engine performance is not within specifications. A tune-up consists essentially of checking engine operation with Original Equipment Manufacturer’s specifications. With reference to today’s “self-tuning” vehicles, the meaning of the term “tune-up” has changed significantly. Your supplier offers a wide range of tools and equipment necessary to perform these tasks. You may also need tools and equipment to check engine rpm, breaker point dwell (for conventional ignition systems), or to apply vacuum to the vacuum advance diaphragm on the distributor during advance checks. The advance timing light provides the additional ability to check the operation of your vehicle’s mechanical or vacuum advance timing controls.
Your timing light provides a simple and efficient means of checking your vehicle’s timing. An ignition system timing check is critical during any tuneup procedure. Proper ignition timing is critical in order to achieve peak engine performance and to ensure maximum fuel economy.
