Will this pump fit my washer reservoir without modification?

Yes. This pump mounts directly into the factory reservoir using the original hole pattern — no drilling or adapter needed. Just swap the old unit out and drop the new one in.

What about the hose and clips — are those included?

The pump assembly itself is included. You'll reuse the hose, clips, and connectors from your current setup. If any hose is cracked or deteriorated, grab replacement tubing separately.

How do I know if my current pump is actually dead?

Pump failure usually means no spray at all, even when the motor sounds like it's running. If you hear the motor but get no fluid, the impeller is likely seized. If there's no sound and no spray, the motor has failed — this pump will fix both.
