Tools You'll Likely Need:
* Socket set (likely 8mm, 10mm, and possibly others)
* Ratchet and extensions
* Flathead screwdriver
* Pliers
* New windshield washer pump
* Shop towels or rags
Steps:
1. Locate the Washer Pump: The pump is usually located in the wheel well, typically the passenger side (right side). You'll need to access it from under the vehicle. You may need to remove some plastic underbody shielding to get a clear view.
2. Disconnect the Battery (Important!): Always disconnect the negative (-) battery terminal before starting any electrical work to prevent short circuits.
3. Remove the Access Panel/Shielding: Carefully remove any plastic covers or shields that are obstructing access to the pump. This often involves removing fasteners (screws or clips). Take your time and note how things come apart for easy reassembly.
4. Disconnect the Washer Lines: The pump will have two or three lines connected to it: one for the reservoir inlet, one for the washer fluid jets (front windshield), and possibly one for the rear washer (if equipped). Use pliers to carefully disconnect these lines. It's helpful to have a container ready to catch any remaining fluid. These lines may be held on by clamps or simply pushed onto the pump nipples. Note their position for reassembly.
5. Disconnect the Electrical Connector: Unplug the electrical connector from the pump. This connector may be held in place by a clip or locking mechanism. Gently wiggle it to release.
6. Remove the Pump: The pump is typically secured with either screws or a retaining clip. Remove the fasteners and carefully remove the pump from its housing.
7. Install the New Pump: Install the new pump, ensuring it is properly seated in its housing. Secure it with the screws or clip.
8. Reconnect Everything: Reverse the removal process. Reconnect the electrical connector, the washer lines, and the access panels.
9. Refill the Washer Fluid Reservoir: Make sure to refill the washer fluid reservoir.
10. Reconnect the Battery: Reconnect the negative (-) battery terminal.
11. Test the System: Test the windshield washers to make sure the new pump is working correctly.
Important Considerations:
* Bleeding the System: After installation, you may need to "bleed" the system of air bubbles. This might involve running the washer fluid several times until the flow is consistent.
* Fluid Type: Use the correct type of washer fluid for your climate. Never use water alone, as it can freeze and damage components.
* Repair Manual: As mentioned, a repair manual specific to your 1998 Ford Explorer will be invaluable. It will provide detailed diagrams and instructions, making the process much easier and safer. You can often find these online (often for a small fee).
If you are uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. This is a relatively minor repair, but working under a car can be dangerous if not done properly.
