Will this pump work with my factory washer fluid hose and connector?

Yes. This is a direct OEM replacement, so all factory hose fittings and electrical connectors mate without adapters or modification.

Does this pump come with a motor and impeller pre-assembled?

The assembly ships as a complete, ready-to-install pump unit with motor and internal impeller integrated. No disassembly or parts sourcing needed.

What should I do before installing this pump?

Test the pump on a bench with 12V power before final mounting to confirm operation. Inspect your factory hose and connectors for cracks or debris—clear any blockages in the washer nozzles before reinstalling.
