Will this pump work with my existing washer hose and nozzles?

Yes. This pump is engineered to match OEM flow rate and pressure, so your current hoses and nozzles will perform exactly as they did on the original. No modifications needed.

Do I need to drain the reservoir before installation?

It's recommended. Drain what you can to minimize spillage during removal and reinstallation. The pump mounting is straightforward, but a clean workspace saves time.

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

Check your hoses for blockages or pinch points first. Make sure the reservoir has fluid and that the hose connections are tight at both the pump and nozzles. If spray is still weak, the nozzles themselves may be clogged — run hot water through them or soak in vinegar to clear mineral buildup.
