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

Yes—this pump is built to original specifications, so your OEM hose and wiring harness mate directly without adapters or splicing.

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

Air locks happen. Fill your washer reservoir, cycle the pump a few times, then test. If spray stays weak or absent after that, the unit qualifies for return—contact support with photos of the connector and wiring to confirm proper install first.

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

Draining makes the job cleaner, but not mandatory. The pump sits at the tank bottom, so you'll lose some fluid when you disconnect the hose. Have a catch pan ready either way.
