3. Installation Instructions

Important: Installation of automotive components can be complex. If you are not experienced with vehicle maintenance, it is recommended to seek professional assistance for installation to ensure proper function and safety.

This pump is typically located at the bottom of the windshield washer fluid reservoir.

1. Preparation: Ensure the vehicle is turned off and the ignition key is removed. Disconnect the negative terminal of the vehicle's battery for safety.
2. Access the Reservoir: Locate the windshield washer fluid reservoir. Depending on your vehicle model, this may require removing other components such as fender liners, headlights, or bumper covers.
3. Drain Fluid: If possible, drain the washer fluid from the reservoir.
4. Disconnect Electrical Connector: Carefully disconnect the electrical wiring harness from the existing washer pump.
5. Remove Hoses: Disconnect the washer fluid hoses from the pump. Be prepared for residual fluid to leak.
6. Remove Old Pump: The pump is usually held in place by a rubber grommet. Gently pull or twist the old pump out of the reservoir.
7. Inspect and Replace Grommet: It is highly recommended to replace the rubber grommet (part number 90068-32002, if applicable for your vehicle) that seals the pump to the reservoir. Old grommets can become swollen or brittle, leading to leaks.
8. Install New Pump: Insert the new Toyota 85330-50020 pump into the reservoir, ensuring it is seated firmly and securely in the new grommet.
9. Reconnect Hoses and Electrical: Reattach the washer fluid hoses and the electrical connector to the new pump. Ensure all connections are secure.
10. Refill Reservoir: Fill the reservoir with appropriate windshield washer fluid.
11. Test Functionality: Reconnect the vehicle battery. Turn on the ignition and test the windshield washer system to ensure the pump operates correctly and there are no leaks.

4. Operation

The Toyota 85330-50020 Windshield Washer Motor and Pump Assembly functions automatically when the vehicle's windshield washer system is activated. When the washer stalk or button is engaged, the pump draws fluid from the reservoir and delivers it under pressure through the washer nozzles onto the windshield.

Ensure the washer fluid reservoir is adequately filled for proper operation. Using appropriate washer fluid, especially in freezing conditions, is crucial for preventing damage to the system.

5. Maintenance

• Fluid Level Check: Regularly check the windshield washer fluid level and refill as needed.
• Fluid Type: Use only recommended windshield washer fluid. Do not use plain water, especially in cold climates, as it can freeze and damage the pump or lines.
• Hose Inspection: Periodically inspect the washer fluid hoses for cracks, leaks, or blockages.
• Nozzle Inspection: Ensure washer nozzles are clear and properly aimed for effective cleaning.

6. Troubleshooting

If the windshield washer system is not functioning correctly after installation or during normal use, consider the following:

• No Fluid Spray:
  • Check washer fluid level in the reservoir.
  • Inspect for clogged washer nozzles.
  • Verify electrical connection to the pump.
  • Check for blown fuses related to the washer system.
  • Listen for pump operation when activated; if no sound, the pump may not be receiving power or is faulty.
• Weak Fluid Spray:
  • Check for partial clogs in nozzles or hoses.
  • Ensure hoses are not kinked or pinched.
  • Confirm the pump is securely seated and the grommet is not leaking, which could reduce pressure.
• Leaks:
  • Inspect the grommet seal between the pump and the reservoir.
  • Check hose connections for tightness.
  • Examine hoses for cracks or damage.

If troubleshooting steps do not resolve the issue, professional diagnosis and repair may be necessary.
