Is your speedometer on your 85 Silverado acting up? Are you experiencing issues such as inaccurate readings or a completely non-functioning speedometer? If so, it may be time to replace the speedo cable. In this guide, we'll walk you through the step-by-step process of replacing the speedo cable in your 85 Silverado. So grab your tools and let's get started!

🛠️ Preparing for the Speedo Cable Replacement

Before you dive into the speedo cable replacement process, you'll want to make sure you have all the necessary tools and equipment. Here's a list of items you'll need:

• Socket set
• Screwdriver
• Pliers
• New speedo cable

Ensure you have these tools readily available before proceeding to the next steps.

🚗 Removing the Dash Trim

The first step in replacing the speedo cable is removing the dash trim. This will give you access to the cluster and allow you to remove the speedo cable. Follow these steps to remove the dash trim:

1. Locate the screws holding the dash trim in place. There should be three screws: one on the bottom and two on the side.
2. Use a screwdriver or socket set to remove the screws.
3. Carefully detach the plastic screen or glass from the dash. This may require removing additional screws.
4. Set the dash trim aside for reassembly later.

🔒 Accessing the Speedo Cable

Once the dash trim is removed, you'll have access to the cluster and the speedo cable. However, before you can remove the cluster and the cable, you'll need to create some slack in the cable. Follow these steps to access the speedo cable:

1. Climb under the truck to locate the speedo cable at the transmission.
2. Unscrew the speedo cable from the transmission using a socket set.
3. Look for two nuts of different sizes and remove them.
4. Pull the rubber grommet through the hole in the firewall to create slack in the cable.

🌟 Removing the Cluster

With the necessary slack created in the speedo cable, you can now proceed to remove the cluster. Follow these steps to remove the cluster:

1. Identify any wires connected to the cluster and unplug them. Take note of their placement for reassembly.
2. Remove any clips or clamps holding the cluster in place.
3. Carefully slide the cluster out, being cautious of any brittle components.
4. Set the cluster aside for further access to the speedo cable.

🔌 Disconnecting Wires and Removing Gear Shift Indicator

Before you can completely remove the speedo cable from the cluster, you'll need to disconnect some wires and remove the gear shift indicator. Follow these steps to proceed:

1. Carefully unplug any wires connected to the cluster. Take pictures or notes for reference during reassembly.
2. Remove the gear shift indicator, which tells you what gear you're in. Be mindful of any clips or screws holding it in place.
3. Set the gear shift indicator aside for now, ensuring not to damage it.

🗝️ Releasing the Speedo Cable from the Cluster

Now that you've disconnected the necessary wires, it's time to release the speedo cable from the cluster. Follow these steps to release the cable:

1. Locate the pin on the cluster that secures the speedo cable.
2. Push the pin down towards the cluster to release the cable.
3. Once released, carefully pull the cable out of the cluster.

🚀 Removing the Speedo Cable from the Vehicle

With the cable released from the cluster, it's time to remove it from the vehicle entirely. Carefully follow these steps:

1. Remove any remaining clamps or screws holding the cable in place.
2. Carefully pull the cable out of the motor, ensuring not to damage any components.
3. Take note of the cable's condition and any signs of wear or damage.

⚙️ Installing the New Speedo Cable

Now that the old cable is removed, it's time to install the new speedo cable. Follow these steps to complete the installation:

1. Insert the new cable into the motor and secure it with clamps or screws.
2. Gently feed the cable through the firewall and into the cluster.
3. Align the pin on the cluster with the hole in the cable and push it in to secure the connection.
4. Ensure the cable is properly seated and secured in place.

🛠️ Reassembling the Cluster and Dash Trim

With the new speedo cable installed, it's time to reassemble the cluster and dash trim. Follow these steps for a successful reassembly:

1. Reconnect any wires that were previously disconnected.
2. Carefully slide the cluster back into its original position.
3. Secure the cluster in place by reattaching any clips or clamps.
4. Reinstall the gear shift indicator, ensuring a secure fit.
5. Reattach the dash trim using the screws you originally removed.
