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

Yes. This pump uses the same inlet, outlet, and electrical connector as the factory unit—your existing hoses and wiring harness bolt straight on without any adapter or modification.

Do I need to drain the washer fluid reservoir before installing this?

It's not required, but draining first makes the job cleaner and prevents spills. The pump sits inside the reservoir, so disconnecting the old unit will release some fluid regardless.

What if the pump doesn't spray after installation?

Check that the intake port isn't blocked by debris or sediment in the reservoir, and confirm the electrical connector is fully seated. If fluid still won't flow, your hose lines may be kinked or clogged—run a clear line from the pump outlet to test pressure at the nozzles.
