Will this pump work with my existing hose connections?

Yes. This pump uses factory connector specifications and mounts directly into the OEM reservoir without adapter fittings or hose modification.

Do I need to drain or remove the washer fluid reservoir to install this?

Depends on your reservoir design and your comfort level. Most owners either drop the reservoir to access the pump cavity cleanly or work from below. Check your service manual for access points specific to your Liberty.

What if the pump doesn't spray after installation?

Check that electrical connectors are fully seated, fluid level is adequate, and hose lines aren't kinked or blocked. If spray remains weak or absent, test voltage to the pump with a multimeter—a dead circuit means wiring or switch issue, not the pump itself.
