How to replace a windshield wiper pump

How to replace a windshield Wiper pump. Keeping a car’s windshield clean is important. In dirty environments, the small pump that distributes the windshield washer fluid works overtime. This can cause the pump to wear out, and over time it could break.

In cold climates, windshield washer fluid can freeze and expand inside the pump, causing irreparable damage. If the windshield of the pump cleaner breaks, you can easily change the pump at home and save the bill for an unnecessary mechanic.

  2. Remove the electrical connector of the fluid pump below the reservoir. Pull the connector by hand.
  3. Remove the hose between the reservoir and the pump. Loosen the hose clamp with a screwdriver.
  4. Remove the screws that hold the pump to the cab frame. Remove the pump.
  5. Bolt of the new pump to the frame. Replace everything in reverse order.
