To refill it, you'll likely need to:
1. Access the cargo area: Remove any cargo or obstructions from the rear of the Explorer.
2. Locate the access panel: This is usually a panel in the floor, sometimes covered by carpeting or a plastic panel. It might be near the side or center of the cargo area. You might need to feel around to find it, as it's not always obvious. Some Explorers have a small cutout where you can reach the reservoir through the existing carpet. Others may require removing a portion of the carpet.
3. Remove the access panel: This may involve simply lifting it up or using a trim tool to carefully pry it loose (be gentle to avoid breaking clips).
4. Locate the reservoir: Once the panel is removed, you should see a small reservoir tank. It might be a small plastic bottle or a portion of a larger tank.
5. Fill the reservoir: Carefully pour washer fluid into the reservoir. Don't overfill.
6. Replace the access panel: Securely put the access panel back in place.
Important Considerations:
* Consult your owner's manual: The best and most accurate information will be in your 1998 Ford Explorer's owner's manual. It should have diagrams or instructions specifically for your vehicle.
* Use the correct fluid: Use only washer fluid designed for use in all weather conditions, especially if you live in an area with freezing temperatures. Never use plain water, as it can freeze and damage the system.
* If you can't find it: If you're having trouble locating the access panel or reservoir, a local Ford dealer or mechanic might be able to assist.
Remember to be patient and methodical when searching for the reservoir. It's often hidden well.
