Will this pump work with my existing washer fluid reservoir and hoses?

Factory hoses and reservoirs on 3-Series models use standard quick-disconnect fittings. Verify your hose diameters before installation to avoid leaks or pressure loss.

Do I need to drain the washer fluid before swapping pumps?

Recommended. Empty the reservoir first to prevent fluid spillage during removal and reinstallation. You'll have easier access to the pump connection and cleaner workspace.

Is any wiring modification needed to install this pump?

The factory connector matches OEM specifications, so no cutting or splicing required. Plug directly into the existing harness and secure the pump to its mounting bracket.
