Will this pump work with my existing washer fluid hoses?

Yes, this pump is designed to connect directly to OEM hose sizes and fittings. Just verify your hoses are in good condition before installation — cracked or deteriorated lines can reduce spray pressure.

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

You should drain or remove as much fluid as practical to avoid spillage during removal and installation. Some residual fluid is normal and won't affect the new pump's operation.

What if the pump doesn't spray immediately after install?

Air can get trapped in the lines after a pump swap. Run the washer a few times in short bursts to bleed the system. If spray remains weak or uneven, check that hoses aren't kinked or disconnected at the nozzles.
