1. Identify the Cable and Components:
* Throttle Cable: Locate the cable itself. It's usually a metal-sheathed cable running from the carburetor (or throttle body if it's fuel-injected, though less likely on an '83) to the pedal assembly inside the cab.
* Throttle Linkage: This connects the cable to the carburetor or throttle body.
* Pedal Assembly: Locate the accelerator pedal and its linkage inside the truck.
* Cable Routing: Observe the existing cable's path (if replacing) to understand where it needs to run. It usually runs along the firewall and engine compartment, often secured with clips.
2. Preparation:
* Disconnect the Old Cable (if replacing): Carefully disconnect the old cable from both the carburetor/throttle body and the pedal assembly. Take note of how it's attached.
* Clean the Connections: Clean any dirt or debris from the throttle linkage and pedal assembly connection points.
3. Installation:
* Connect to the Throttle Body/Carburetor: Carefully attach the new cable to the throttle linkage. This usually involves a clevis pin or a similar mechanism. Ensure it moves freely and smoothly without binding. The linkage should have a small amount of play, not be stiff.
* Connect to the Accelerator Pedal: Attach the other end of the cable to the accelerator pedal assembly. Again, this will usually involve a clevis pin or similar attachment.
* Route the Cable: Carefully route the cable along its intended path, securing it with the appropriate clips or retainers. Ensure the cable doesn't rub against hot engine parts or sharp edges.
* Adjust Cable Tension: This is crucial. Too loose, and the throttle won't open fully. Too tight, and the engine might idle high or the pedal might be stiff. There is usually an adjustment mechanism at either the carburetor/throttle body end or the pedal end (or both). Your repair manual will detail the proper adjustment procedure. Often, you'll want to start with a little slack and then adjust. Many manuals specify a measurement of slack or play at the pedal.
4. Testing:
* Reconnect the Battery: Reconnect the negative battery terminal.
* Test the Accelerator: Carefully press the accelerator pedal. The engine should respond smoothly and proportionally to the pedal's movement. The throttle should close completely when you release the pedal. If there is any sticking, binding, or hesitation, re-check the cable routing and adjustments. If it's idling too high or too low, adjust the throttle cable accordingly.
Important Considerations:
* Repair Manual: A factory service manual specific to your 1983 Chevy Silverado C-10 is invaluable. It will provide detailed diagrams, specifications, and torque values.
* Fuel Injection vs. Carburetor: The installation procedure varies slightly depending on whether your truck has a carburetor or fuel injection.
* Professional Help: If you're uncomfortable working on your vehicle, it's best to consult a qualified mechanic. Incorrect cable adjustment can lead to drivability problems or even damage to your engine.
This is a general outline. Always refer to your specific vehicle's repair manual for detailed instructions and safety precautions. Failing to follow the correct procedure could lead to engine damage or injury.
