Tools you'll likely need:
* Socket set: Various sizes, including possibly a 10mm, 8mm, and possibly others.
* Wrench set: Similar range to sockets.
* Screwdrivers: Phillips and flathead, various sizes.
* Pliers: Needle-nose pliers might be helpful.
* Shop rags or paper towels: To clean up spills and keep things tidy.
* New wiper pump: Ensure you get the correct replacement part for your vehicle. Your VIN number will help ensure you get the correct part.
* Washer fluid: To refill the reservoir after the job is complete.
* Drain pan (optional): To catch any spilled washer fluid.
Procedure (General Steps - Refer to your repair manual for precise details):
1. Disconnect the battery: This is a crucial safety step to prevent accidental shorts or shocks. Disconnect the negative (-) terminal first.
2. Access the washer pump: This is usually located under the hood, near the washer fluid reservoir. The location can vary slightly depending on your specific model. You may need to remove some air intake components or other parts to gain access. Your repair manual will show you the exact location and any components that need removal.
3. Disconnect the electrical connector: Carefully unplug the electrical connector from the pump. Take a picture or make a note of how it connects for reassembly.
4. Disconnect the washer fluid lines: There are usually two lines connected to the pump – an inlet and an outlet. Use pliers to gently squeeze the clamps and disconnect the hoses. Have rags ready to absorb any spilled fluid.
5. Remove the pump: The pump is usually held in place by a few screws or clips. Use the appropriate tools to remove these fasteners and carefully remove the pump from its location.
6. Install the new pump: Carefully install the new pump in the reverse order of removal. Make sure the pump sits securely and all fasteners are tightened.
7. Reconnect the washer fluid lines: Reconnect the inlet and outlet hoses, ensuring a secure fit and clamping them correctly.
8. Reconnect the electrical connector: Reconnect the electrical connector to the new pump, matching it to your previous notes or picture.
9. Reconnect the battery: Reconnect the positive (+) terminal followed by the negative (-) terminal.
10. Test the system: Turn on your windshield wipers and use the washer fluid to test the new pump. Check for leaks around the connections.
Important Considerations:
* Repair Manual: This is absolutely vital. Following generic instructions without a repair manual specific to your vehicle can lead to damage or incorrect installation.
* Fluid Type: Use the correct type of washer fluid for your climate and vehicle.
* Leaks: Carefully check for leaks after installation.
If you are uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. Replacing a windshield wiper pump is not overly complex but requires careful attention to detail. A mistake can lead to further damage or incorrect operation.
