1. Locate the Leak:
* Top off the fluid: Add windshield washer fluid and carefully observe where the fluid is leaking. Look for wet spots, drips, or puddles under the vehicle. Pay close attention to the reservoir itself, the hoses connected to it, and the connections at the pump. A flashlight can be very helpful.
* Visual Inspection: Once the leak is visually located, assess the damage. Is it a crack in the plastic reservoir? A split or disconnected hose? A loose clamp? A bad seal around the pump or cap?
2. Repair (If Possible):
* Minor Cracks/Leaks in the Reservoir: Small cracks *might* be temporarily patched with a plastic weld kit designed for this purpose. However, this is a temporary fix at best. The reservoir is under pressure, and the patch might fail, requiring a complete replacement.
* Loose Hoses/Clamps: Tighten any loose hose clamps. If the hose is cracked or damaged, replace it.
* Faulty Cap: If the leak seems to originate from the cap, replace the cap. It's inexpensive and relatively easy.
* Pump Seals: Leaks around the pump are more complex. They often require removing the pump to replace seals or the pump itself. This is a more advanced repair.
3. Replacement (Most Likely Solution):
Replacing the entire reservoir is usually the most practical solution, especially if there's a significant crack or the leak is in a hard-to-reach area. Here's a general outline:
* Gather Supplies: You'll need a new windshield washer fluid reservoir (check a parts store like AutoZone, Advance Auto Parts, or online retailers with your Jeep's VIN for the correct part), a few new hose clamps, and possibly new hoses if needed. Having a shop manual specific to your 2006 Jeep Liberty would be very beneficial.
* Access the Reservoir: This varies depending on the Liberty's trim level. You'll likely need to remove some under-hood components to gain proper access. This *will* involve some disassembly. Consult a repair manual for detailed instructions on removing any shrouds, components, etc. obstructing access to the reservoir. Pictures taken *before* you begin disassembly are highly recommended.
* Disconnect the Hoses and Pump: Carefully disconnect the hoses from the old reservoir. Note the position and routing of each hose so you can reassemble correctly. You'll likely need to remove the pump as well.
* Remove the Reservoir: Carefully remove the old reservoir.
* Install the New Reservoir: Install the new reservoir, carefully connecting the hoses and pump in their original positions, ensuring the connections are tight and secure. Use new hose clamps if necessary.
* Reassemble: Reinstall any removed under-hood components.
* Test: Fill the new reservoir with fluid and check for leaks.
Important Considerations:
* Repair Manual: A repair manual specific to your 2006 Jeep Liberty is highly recommended. It will provide detailed diagrams, instructions, and torque specifications.
* Difficulty: Replacing the reservoir can be moderately challenging depending on your mechanical aptitude. If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
* Safety: Always disconnect the negative battery terminal before starting any work on the electrical system, especially near the pump.
Remember to always double-check your work and ensure all connections are secure to prevent further leaks. If you're unsure about any step, it's best to seek professional help.
