Tools You'll Need:
* New speedometer cable: Make sure you get the correct one for your year and model S10.
* Socket set: Various sizes, likely including 7/16" and possibly others depending on your specific year.
* Pliers: Needle-nose pliers will be helpful.
* Screwdrivers: Phillips and possibly flathead, depending on your truck.
* Wrench: Possibly a wrench to loosen the transmission connector.
* Jack and jack stands (optional but recommended): Makes accessing the cable easier.
* Shop rags or paper towels: To clean up any grease or dirt.
* Penetrating oil (optional but helpful): May help loosen stubborn connections.
Steps:
1. Safety First: Engage the parking brake firmly. Chock the wheels if you're using a jack. Wear safety glasses.
2. Access the Speedometer Cable: The cable typically runs from the transmission to the instrument cluster in the dashboard. You'll need to access both ends.
* Transmission End: This is usually located on the side or bottom of the transmission. You may need to remove some underbody protection or access panels to get a clear view.
* Instrument Cluster End: This is accessed by removing the instrument cluster bezel (the plastic trim surrounding the gauges). This usually involves unscrewing several screws. Consult your vehicle's repair manual for specific instructions on removing the bezel.
3. Disconnect the Old Cable:
* Transmission End: This is usually a simple clip or retainer. Use pliers or your fingers to carefully disconnect it. Sometimes, you'll find a nut to unscrew. Penetrating oil may be helpful here if things are stuck.
* Instrument Cluster End: This is typically a simple connection at the back of the speedometer. Carefully disconnect it. Again, use caution and potentially needle-nose pliers.
4. Remove the Old Cable: Gently work the old cable out of its routing. Be mindful of where it runs to avoid snagging it on anything.
5. Install the New Cable:
* Transmission End: Carefully feed the new cable into the transmission, ensuring it's correctly seated. Secure it with the clip or nut.
* Instrument Cluster End: Connect the new cable to the back of the speedometer.
6. Reconnect Everything: Reinstall the instrument cluster bezel and any underbody panels you removed.
7. Test: Start the engine and check if the speedometer works correctly. If not, double-check all connections.
Important Considerations:
* Year and Model Specifics: The exact location and method of connection may vary slightly depending on the year and model of your S10. Consult a repair manual specific to your truck year for detailed diagrams and instructions. A Haynes or Chilton manual is a good investment for this type of work.
* Lubrication: Some people suggest lightly lubricating the cable before installation. Check your new cable's packaging for any recommendations.
* Difficulty: If you encounter significant difficulty removing or installing the cable, consult a qualified mechanic. Forcing things could cause damage.
This guide provides general steps. Always refer to a repair manual specific to your vehicle's year and model for the most accurate and detailed instructions. Failing to do so could lead to improper installation and potential damage.
