3. Installation Guide
Installation of the ACI 377140 Windshield Washer Pump typically involves replacing the existing pump. While the process can vary by vehicle model, the general steps are outlined below. It is recommended to consult your vehicle's service manual for specific instructions related to your make and model.
- Safety First: Ensure the vehicle is turned off and the parking brake is engaged. Disconnect the negative terminal of the battery to prevent electrical hazards.
- Locate the Washer Reservoir: The windshield washer pump is usually located at the bottom of the windshield washer fluid reservoir. Access to the reservoir may require removing fender liners, bumper components, or other under-hood parts depending on the vehicle.
- Drain Fluid: If possible, drain the washer fluid from the reservoir to minimize spillage during pump removal.
- Disconnect Electrical Connector: Carefully disconnect the electrical connector from the old pump.
- Remove Hoses: Disconnect the washer fluid hoses from the old pump. Be prepared for some fluid to leak out.
- Remove Old Pump: The pump is typically held in place by a rubber grommet or a clip. Gently pull or unclip the old pump from the reservoir.
- Install New Pump: Insert the new ACI 377140 pump into the reservoir opening, ensuring it seats firmly in the grommet.
- Reconnect Hoses and Electrical: Reattach the washer fluid hoses to the new pump and securely connect the electrical connector.
- Refill Reservoir: Fill the washer fluid reservoir with appropriate windshield washer fluid.
- Test Operation: Reconnect the battery, turn on the vehicle, and test the windshield washer system to ensure proper function and check for leaks.
Note: Some vehicle designs may require significant disassembly of surrounding components to access the washer pump. Patience and proper tools are essential for a successful installation.
4. Operating Instructions
The ACI 377140 Windshield Washer Pump operates as part of your vehicle's existing windshield washer system. Once installed, its operation is integrated with your vehicle's controls.
- Activation: To activate the pump, use the windshield washer stalk or button inside your vehicle, typically located on the steering column. Refer to your vehicle's owner's manual for the exact control mechanism.
- Fluid Delivery: Upon activation, the pump draws fluid from the reservoir and delivers it under pressure through the washer nozzles onto the windshield.
- Wiper Activation: In most vehicles, activating the washer pump will also automatically engage the windshield wipers for a few cycles to clear the fluid and debris.
Ensure the washer fluid reservoir is adequately filled for optimal performance.
5. Maintenance
The ACI 377140 Windshield Washer Pump is designed for durability and requires minimal direct maintenance. However, maintaining the overall windshield washer system will ensure the longevity and performance of the pump.
- Fluid Level: Regularly check and maintain the windshield washer fluid level in the reservoir. Do not allow the reservoir to run dry, as this can cause the pump to run without lubrication and potentially shorten its lifespan.
- Fluid Type: Use only approved windshield washer fluid. Avoid using plain water, especially in freezing temperatures, as it can freeze and damage the pump or lines.
- Nozzle Clogs: Periodically check the windshield washer nozzles for clogs. Clogged nozzles can increase back pressure on the pump, potentially leading to premature wear. Clear any blockages using a fine needle or pin.
- System Leaks: Inspect hoses and connections for any signs of leaks. Leaks can reduce fluid pressure and cause the pump to work harder.
