Will this pump work with my existing washer fluid reservoir?

Yes. This pump mounts and seals to the factory Rio reservoir — no adapter or modification required. Fluid capacity and drain holes remain the same.

Do I need any tools or fasteners to install this?

You'll need a screwdriver and basic hand tools to remove the old pump and secure the new one. The electrical connector plugs in directly. Check your service manual for torque specs on the reservoir mounting bolts.

What if the pump doesn't spray evenly after installation?

Air in the lines is usually the culprit. Run the washer for 10–15 seconds to purge the system. If spray remains uneven, inspect the nozzles for debris and clean with compressed air.
