Will this pump work with my vehicle's existing hose and nozzle setup?

Yes. This pump uses factory electrical connectors and mounts at the same points as the OEM pump, so all existing lines and spray nozzles bolt up without modification.

Do I need to drain the washer fluid reservoir before installation?

It's smart to drain or siphon out the old fluid first — gives you cleaner access inside the reservoir and prevents spillage during pump removal. Not required, but easier work.

What if the pump doesn't spray right after I install it?

Check that the intake tube inside the reservoir is properly seated on the pump inlet, and run the washer system with the cap off briefly to clear any air in the lines. If pressure still seems weak, inspect the spray nozzles for debris.
