4.2. Removal of Old Pump
- Locate the Washer Fluid Reservoir: The washer fluid reservoir is typically located under the hood, often on one side of the engine bay.

- Disconnect Electrical Connector: Carefully disconnect the electrical connector from the old washer pump.
- Disconnect Hoses: Disconnect the washer fluid hoses from the pump. Be prepared for some residual fluid to leak out.

- Prepare New Pump: Ensure the new ACI pump has its rubber grommet properly seated (if applicable).
- Install Pump into Reservoir: Carefully insert the new pump into the opening on the washer fluid reservoir. Ensure it is seated firmly and securely.
- Connect Hoses: Reconnect the washer fluid hoses to the appropriate outlets on the new pump. Ensure a snug fit to prevent leaks.
- Connect Electrical Connector: Reconnect the electrical connector to the new pump.
- Refill Reservoir: Fill the washer fluid reservoir with fresh, appropriate windshield washer fluid.
- Test System: Turn on the vehicle's ignition (do not start the engine unless necessary for testing) and activate the windshield washer system to check for proper operation and leaks. Observe the spray pattern and ensure fluid is delivered to the windshield.
- Secure Components: Reinstall any removed components (e.g., fender liners, covers) that were necessary to access the pump.
Note: This is a direct replacement auto part. If you encounter difficulties or are not confident in performing the installation, it is recommended to seek assistance from a certified mechanic.

Proper maintenance of your windshield washer system ensures optimal visibility and extends the life of the pump.
- Fluid Level Check: Regularly check the washer fluid level in the reservoir and refill as needed with a high-quality windshield washer fluid suitable for your climate. Do not use plain water, especially in freezing temperatures.
