Tools you'll likely need:
* New speedometer cable: Ensure you get the correct one for your van's engine and transmission.
* Socket set and wrenches: Various sizes will be necessary.
* Screwdrivers: Phillips and possibly flathead.
* Pliers: Needle-nose pliers may be helpful.
* Jack and jack stands: Safely lift and support the van.
* Wheel chocks: For added safety.
* Penetrating oil (PB Blaster or similar): To help loosen rusted or seized connections.
* Shop rags: To clean up grease and oil.
* Torque wrench: For proper tightening of fasteners.
Steps:
1. Safety First: Park the van on a level surface, engage the parking brake, and chock the wheels. Wear safety glasses.
2. Locate the Cable: The speedometer cable runs from the transmission to the instrument cluster in the dashboard. You'll need to trace its path. Part of it may be under the van, requiring you to get underneath.
3. Disconnect the Cable at the Transmission: This is often the most challenging part.
* Access: You'll likely need to work under the van. You may need to remove some parts like the lower splash shield or other components to gain better access.
* Disconnect: The cable usually connects to the transmission with a retaining clip or a nut. Use penetrating oil if needed to loosen it. Sometimes a small retaining clip is present. Carefully remove the cable from the transmission. Take note of how it's routed and attached.
4. Disconnect the Cable at the Instrument Cluster:
* Access: This usually involves removing parts of the dash or instrument cluster bezel. Consult your repair manual for the precise procedure.
* Disconnect: The cable typically connects to the speedometer mechanism with a fitting. Carefully disconnect it.
5. Install the New Cable:
* Lubrication: Lightly lubricate the new cable with a suitable grease (consult your manual).
* Connection at the Transmission: Carefully feed the new cable into place, following the path of the old cable. Attach the cable to the transmission using the same retaining clip or nut.
* Connection at the Instrument Cluster: Connect the other end to the speedometer mechanism.
6. Reassembly: Carefully put everything back together, ensuring all fasteners are securely tightened. Double-check all connections.
7. Test: Lower the van, start the engine, and check if the speedometer works correctly.
Important Notes:
* Consult Your Repair Manual: This is crucial. The exact procedures and locations of components can vary depending on your specific van's configuration.
* Take Pictures: Before disconnecting anything, take photos to help you remember how everything goes back together.
* Patience: This is not a quick job. Take your time and work carefully to avoid damaging anything.
* Professional Help: If you're uncomfortable with any part of this process, consider taking your van to a qualified mechanic. A small mistake can lead to further damage.
Remember safety is paramount. If you are unsure about any step, seek professional assistance.
