A stretched timing belt can lower the efficiency of your engine.
Over time the timing chain, also known as a timing belt or cam chain, in a Chevy truck can become worn and stretched. It is a primary part of your truck's engine system. This chain runs through all of the valves and all of the engine parts assuring that they run in a properly coordinated manner. You may need to call a professional to complete the job unless you have experience in working with Chevy trucks.
Instructions
1. Start the truck by turning the key in the ignition to the On position. Allow it to run for 5-10 minutes until it is warmed up to the average running temperature.
2. Press the gas pedal 2-3 times so that the engine reaches 3,000 RPMs.
3. Turn off the truck by turning the key in the ignition to the Off position.
4. Raise the hood of the Chevy truck. Release the hood latch and prop the hood up on the hood support bar located in the front area of the truck under the hood.
5. Remove the cap from the ignition timing adjustment by turning it counterclockwise with your hand. This is a yellow cap located on the wiring harness in the rear of the Chevy truck's engine.
6. Connect the pins of the wiring harness to the jumper wire. Clip the brown, green and white wires of the harness to the jumper wire.
7. Attach the timing light cables to the battery in the Chevy truck. Clip the cables to the terminals of the battery.
8. Start the truck again. Turn the key in the ignition to the On position.
9. Loosen the nuts of the distributor cap by turning them counterclockwise with an adjustable wrench.
10. Turn the distributor cab clockwise with your hand. Align the pointer of the timing belt with notch located on the crankshaft pulley.
11. Unclip the wires from the jumper wire. Remove the jumper wire from the truck.
12. Detach the timing light cables from the battery of the truck.
13. Start the truck by turning the ignition key to the On position. Listen to the engine. It should sound smooth without and puttering. Drive the truck gently for at least ten minutes and monitor the sound of the engine and the feel of the drive. Both should remain even and smooth. Any puttering or stalling is a signal that you need to repeat the adjustment process.
