1. Locate the Rear Washer Fluid Reservoir:
* Under the Hood: Most rear washer fluid reservoirs are located under the hood, near the front windshield washer reservoir. Look for a smaller, separate container. It might be labeled or have a diagram indicating its purpose.
* In the Trunk: Some vehicles have the rear washer fluid reservoir in the trunk, often near the spare tire or other storage compartments. Check your car's manual for the exact location.
2. Open the Reservoir Cap:
* Unscrew the Cap: Carefully unscrew the cap of the reservoir. It might be a twist-off or a pull-up cap.
* Remove Any Debris: Clean any dirt or debris from the opening of the reservoir before refilling.
3. Add Washer Fluid:
* Use the Correct Fluid: Always use dedicated rear window washer fluid, not the same fluid as your front windshield. Rear window washer fluid is usually formulated to handle ice and snow more effectively.
* Avoid Overfilling: Add the washer fluid slowly, checking the fluid level regularly. The reservoir usually has a "max" line, so don't overfill it.
4. Secure the Cap:
* Tighten Securely: Once you've added enough fluid, close the cap tightly. Make sure it's completely sealed.
5. Test the System:
* Spray the Rear Window: To confirm the system is working, turn on your rear windshield washer and spray the window.
Important Considerations:
* Check Your Owner's Manual: Your car's owner's manual will provide specific instructions for refilling your rear washer fluid reservoir.
* Winter Conditions: In colder climates, use a washer fluid formulated for winter use to prevent freezing.
* Freezing Temperatures: If you're worried about freezing, you can add a small amount of alcohol to the fluid. However, use this sparingly as too much alcohol can damage the washer pump.
Tips:
* Use a Funnel: To avoid spills, use a funnel to pour the washer fluid into the reservoir.
* Clean Your Reservoir: Periodically, you can clean the washer fluid reservoir and tubing to prevent clogging.
Remember, if you're having trouble locating the reservoir or you're unsure about any part of this process, it's always best to consult your car's owner's manual or consult a professional mechanic.
