1. Preparation:
* Safety First: Disconnect the negative terminal of your battery to prevent electrical shorts.
* Gather Tools: You'll likely need screwdrivers (possibly both Phillips and flathead), pliers, and possibly a socket wrench depending on how the pump is attached. Have rags handy to clean up any spilled fluid.
* Locate the Tank: The washer fluid reservoir is typically located under the hood, often in a corner or tucked away near the firewall or headlight assembly. Consult your owner's manual for the exact location if you're unsure.
* Empty the Tank: Drain as much washer fluid as possible. This will minimize spillage. Use a siphon, pump, or simply carefully tip the tank (be mindful of where the fluid will go).
2. Removal Process (General Steps):
* Disconnect the Lines: There will be at least two lines connected to the reservoir: one for the inlet (where you fill the fluid) and one or more for the outlet(s) to the spray nozzles. Carefully disconnect these lines. They may be clipped on, have quick-disconnect fittings, or use hose clamps. Take pictures before disconnecting to aid in reassembly.
* Disconnect the Pump: Locate the washer pump, usually mounted to the bottom or side of the reservoir. Unplug any electrical connectors to the pump. Then, remove the pump from its mounting bracket. This may involve removing screws, bolts, or possibly clips.
* Remove the Reservoir (if necessary): Some reservoirs can be accessed and the pump replaced without removing the entire tank. Others may require tank removal. If removal is necessary, check for any retaining clips, brackets, or screws holding the tank in place. You may need to loosen or remove these before you can carefully pull the tank out. Pay attention to any wiring or hoses still connected.
3. Pump Replacement:
* Install the New Pump: Once the old pump is removed, install the new pump, making sure it's securely fastened in the same manner as the old one.
* Reconnect Everything: Reconnect the electrical connectors and the inlet and outlet lines. Ensure all connections are secure and tight.
4. Reassembly:
* Carefully reinstall the reservoir (if you removed it). Secure it with all the original fasteners.
* Reconnect the negative battery terminal.
5. Testing:
* Fill the reservoir with fresh washer fluid.
* Test the washer system to make sure the new pump works correctly.
Important Considerations:
* Consult a Repair Manual: A repair manual specific to your 1995 Buick Riviera will be invaluable. It will provide detailed diagrams and instructions tailored to your vehicle. Online resources like Haynes or Chilton manuals might be helpful.
* Variations: The exact location and method of accessing the washer fluid pump can vary even within the same model year due to trim levels or options. Don't be surprised if your experience differs slightly from this general guideline.
* Photography: Take photos as you disassemble the system; this will be crucial during reassembly.
If you are not comfortable working on your car yourself, taking it to a qualified mechanic is always the safest option. This process involves working with fluid and electrical components; improper handling can lead to damage or injury.
