The Correct transaction of a vehicle requires many matters. Fluids obligation to be changed on a habitual intention. Tires desideratum to be rotated. A Disinfected fuel method can prevent Exorbitant fuel consumption and lengthen the career of Glimmer plugs. When the Glimmer plugs obligation to be changed, Chevrolet recommends the wires, cap and rotor be changed besides on most One thousand nine hundred ninety five and older vehicles. Many of these vehicles should besides carry the timing establish, or at least checked, every clock the tuneup is done.
Instructions
1. Fix the decal under the hood that contains the pattern year and engine counsel for the vehicle. These can be located on the fan shroud or circle wells.
2. Set the engine timing material on the sticker. The dope Testament be in this formation "Engine Timing: Five degrees BTDC." This is an example for this procedure. It may also say ATDC or TDC. BTDC mean "before top dead center," ATDC means "after top dead center," and TDC is "top dead center."
3. Connect the positive and negative leads for the timing light to the battery terminals. These leads will be red and black.
4. Locate the crankshaft pulley on the engine. This will be on the front of the engine at the bottom center. On the top of the pulley will be a scale or arrow pointer.
14. When the proper timing is set, tighten the distributor bolt. Recheck the timing on the crankshaft pulley.15. For 4-cylinder engines, this will be the front-most cylinder. Do not disconnect the wire from the plug; the lead should connect around the wire or clamp on the wire itself.
6. Start the vehicle and allow it to idle.
7. Point the timing light at the crankshaft pulley and determine the timing of the engine. The timing will be the number lined up with the pointer above the crankshaft pulley. Any number to the right of the zero is ATDC, any number to the left of the zero is BTDC, and the zero is TDC.
8. Compare the timing to the recommended timing. If the timing is wrong, proceed to the next step.
9. Shut off the vehicle. Locate the distributor bolt under the distributor on the intake. It may be difficult to see. Most Chevrolets have the bolt on the left of the distributor shaft.
10. Attach the distributor wrench to the bolt and loosen one turn.
11. Start the vehicle and allow it to idle.
12. Attempt to rotate the distributor clockwise or counterclockwise. If the distributor will not turn, loosen the bolt until it turns with minimal resistance.
13. Point the timing light at the crankshaft pulley and turn the distributor slowly until the proper timing is achieved.
5. Connect the third lead on the timing light to the spark plug wire for the No. One cylinder. For V6 and V8 engines, this will be the front left cylinder when looking at the front of the engine.
Turn the vehicle off and disconnect the timing light.
